Box and EZ Trim

Flange Detail

Eaton’s new EZ box and EZ trim represents the first significant change in panelboard box and trim designs in more than a half-century. The EZ box and EZ trim have been designed for faster, more secure and safer installa-tions. The new EZ box and EZ trim are provided standard for Cutler-Hammer Pow-R-Line 1a and Pow-R-Line 2a lighting panelboards, as well as our Pow-R-Line 3a mid-range panelboard.

Features

■

Virtually eliminates sharp edges.

■

Trim installs in seconds rather than minutes.

■

Door-in-door is standard.

■

Ability to adjust flush box to wall irregularities.

■

Trim installs without the need for tools.

■

No exposed hardware (because there is none).

■

Multipoint door latch over breakers.

The EZ box flanges are bent and painted, which virtually eliminates the sharp edges associated with traditional boxes. Additionally, all steel panelboard chassis parts are painted. This significantly reduces potential injury for material handlers and install-ers. Each flange is adjustable outward up to 3/4 inch. This feature allows the installer to adjust flush box applications to be level and flat with

the finished wall after the wall material is installed to help correct wall irregularities. The new box flange also provides the means for attaching the EZ trim.

EZ Box and EZ Trim

Fast Installation

The EZ trim incorporates a patent pending, ground breaking design that installs in seconds, rather than minutes. The standard trim features include door-in-door construction; no exposed hardware and no tools are required for installation.

Each EZ trim includes hangers attached on the right side. The bottom trim hanger has a notch in its base. To install, the bottom hanger is inserted into the bottom right side box flange opening, resting the notch on the flange.

Trim Hanger Inserted Into Box Flange

The balance of the hangers are aligned with the other flange openings and pushed in. When all hangers are in the box flange, the trim is lifted up slightly to clear the notch on the bottom hanger, and the trim in self-supported on the EZ box.

The installation is completed by swinging the trim to the closed position, then lifting and pushing slightly to the right. The trim will drop into place totally secured. The multi-point catches on the left side of the trim will lock into the left side box flange openings.

To prevent the trim from being removed by non-authorized persons, a unique sliding means automatically latches in place when the trim door is closed. For added safety, a screw is provided to secure the latch for those who require extra security.

The new EZ trim utilizes an exclusive catch system that fastens the door to multiple points. Along with a new lock, the EZ trim offers a high degree of door security.

Product Description

Lighting and Distribution Panelboards

Eaton’s Cutler-Hammer

T

assembled panelboards are designed for sequence phase connection of branch circuit devices. This allows complete flexibility of circuit arrangement (1-, 2- or 3-poles) to allow balance of the electrical load on each phase.

Sturdy, rigid chassis assembly ensures accurate alignment of interior with panel front; prevents flexing and minimizes possibility of loosening or damage to current carrying parts during and after installation.

Four-point in-and-out adjustment of panel interior is provided to meet criti-cal depth dimensions on flush installa-tions. This compensates for possible misalignment of box at installation.

Main lugs are mechanical solderless type and approved for copper or aluminum conductors.

Enclosures

Boxes are code-gauge galvanized steel except for column type panelboards which include a painted box finished in ANSI-61 light gray to match the trim.

Standard panelboard cabinets are designed for indoor use. Alternate types are available for indoor and special purpose applications.

All enclosures are furnished in accor-dance with Underwriters Laboratories standards and include wiring gutters with proper wire bending space. Special cabinets can be provided at an additional charge.

The box dimensions shown are inside dimensions. For outside dimensions, add 1/4-inch (6.4 mm).

Standard panelboard boxes are supplied

without knockouts (blank endwalls).

Fronts

Fronts (trims) for all panelboards are made of code-gauge steel and have a high durability ANSI-61 light gray finish applied by a baked-on polyester powder coating paint system.

Application Description

The fronts for lighting and appliance branch circuit panelboards and small power distribution panelboards include a door with rounded corners and con-cealed hinges. A flush-type latch and lock assembly is included. All locks are keyed alike. These trims are available in both surface and flush mounted designs.

EZ Trim Features Standard Door-in-Door with No Exposed Hardware or Sharp Edges(no Tools are Required for Installation)

The Three-Piece Trim for Larger Power Distribution Panelboards Provides for Easy Handling and Installation

Fronts for power distribution panel-boards utilize a unique breaker front cover design in which each device has a dedicated bolt-on steel cover. The individual covers form a single dead-front for the panelboard that is used in conjunction with two wiring gutter covers to complete the trim. A door is not finished as part of the standard offering on these panelboards but can be provided, for an additional charge, using a deeper than standard box.

Application Description

Panelboard Selection Factors

In selecting a panelboard, the follow-ing factors must be considered:

■

Service (voltage and frequency).

■

Interrupting capacity (fully or series rated).

■

Ampere rating of main.

■

Ampere ratings of branches.■ Environment.

Panelboard Short Circuit RatingThe short circuit rating of Eaton’s Cutler-Hammer assembled panel-boards are test verified by, and listed with, Underwriters Laboratories (ULT). Generally, these ratings are that of the lowest interrupting rated device in the panel.

Certain exceptions to this rule exist where branch devices have been UL tested in combination with specific main devices having a higher inter-rupting rating. Where these defined main devices and branch breaker com-binations are utilized, the Series Short Circuit Rating of the assembled panel-board will be the same as the tested rating of the approved rated main device in series with the branches. Available main and branch breaker combinations are tabulated starting on Page 14-12. All combinations shown are UL tested and listed.

These series ratings apply to panels having main devices, or main lug only panelboards fed remotely by the device listed in the series ratings chart as the main, for which UL listed tests were conducted.

Service Entrance EquipmentThe National Electrical Code (NECT) requires that:

■ A panel used as service entrance equipment must be located near the point where the supply conductors enter the building.

■ A panelboard having main lugs only shall have a maximum of six service disconnects to de-energize the entire panelboard from the supply conductors. Where more than six disconnects are required, a main service disconnect must be provided.

■ A disconnectable electrical bond must be provided between the neutral and ground.

■ A service entrance type UL label must be factory installed.

■ Ground fault protection of equip-ment shall be provided for each ser-vice disconnect rated 1000 amperes or more if the electrical service is a solidly grounded wye system of more than 150 volts to ground but not exceeding 600 volts phase-to-phase.

Note: Service entrance panels must be identified as such on the order.

Panelboard ClassificationsPanelboards are classified by NEC and UL in two general categories: Lighting and Appliance Panels and Power Distribution Panels.

Lighting and Appliance PanelboardsLighting and appliance branch circuit panelboards are defined in NEC (Article 408) as one having more than 10 percent of its overcurrent devices rated 30 amperes or less for which neutral connections are provided. Article 408 also limits the number of overcurrent devices (branch circuit-poles) to a maximum of 42 in any one cabinet. This rule applies to all panel types including PRL4 when the panel circuitry comes within the scope of this definition. When the 42 devices (poles) are exceeded, two or more separate panels are required.

Power Distribution PanelboardsDistribution panelboards (all others not defined as lighting and appliance branch circuit panelboards) are restricted only to practical physical limitations such as standard box heights and widths. It is important to note that the NEC requires that the operating handle of the topmost mounted device be no more than 6 feet 7 inches (2006.6 mm) above the finished floor.

Additional boxes and fronts are required when the components required for one panelboard exceed the standard box dimensions.

Multi-Section PanelboardsWhen more than 42 overcurrent protective devices are required (See, Lighting and Appliance Panelboards), two or more separate enclosures are required. Separate fronts for each box are standard. A common front can be furnished at additional charge.

Interconnecting Multi-SectionPanelboardsWhen a panelboard, for connection to one feeder, must be furnished in more than one section (Box), each section must be furnished with main bus and terminals of the same rating, unless a main overcurrent device is provided in each section.

Sub-feed or through-feed provisions must also be included (and priced) to provide connection capability to the second section.

Note: Sub-feed or through-feed lugs can-not be used on any panelboard that is not protected by a single main overcurrent device either in the panelboard or immedi-ately upstream, i.e., service entrance panel-boards with main lugs only using the six disconnect rule.

Sub-Feed LugsSub-feed lugs (see Figure 14-1) are one means of interconnecting multi-section panels. The sub-feed (second set of) lugs are mounted directly beside the main lugs. These are required in each section except the last panel in the lineup. The feeder cables are brought into the wiring gutter of the first section and connected to the main lugs. Another set of the same size cables are connected to the sub-feed lugs (Section 1) and are carried over to the main lugs of the adjacent panel. Cross connection cables are not furnished by Eaton. Sub-feed lugs are only available on main lug only panels.

Note: Sub-feed lugs may not be used on main lug only (six disconnect rule) service entrance panels.

Figure 14-1. Sub-Feed Lugs

Through-Feed LugsThrough-feed lugs (see Figure 14-2) are another method to interconnect multi-section panelboards. The incom-ing feeder cables are connected to the main lugs or main breaker at the bot-tom of panel (Section 1). Another set of lugs (through-feed) are located at the opposite end of the main bus. The interconnecting cables are connected to the through-feed lugs in Section 1 and are carried over to the main lugs in Section 2. The connection arrange-ment could be reversed, i.e., main lugs at top; through-feed lugs at bottom end of panel. Cross cables are not furnished by Eaton.

Note: Through-feed lugs may not be used on main lug only (six disconnect rule) service entrance panels.

Figure 14-2. Through-Feed Lugs

Multiple Section Panelboard — Flush MountedShown below is the standard method for flush mounting multiple section lighting and distribution panelboards using standard flush trims.

Figure 14-3. Multiple Section PanelboardFlush Mounted — Dimensions in Inches (mm)

Overcurrent ProtectionThe following requirements will be found in the NEC:

Each lighting and appliance branch circuit panelboard shall be individually protected on the supply side by not more than two main circuit breakers or two sets of fuses having a combined rating not greater than that on the panelboard.

Pow-R-Line C PanelboardsStandards and Certifications

Branch Circuit Loading for Lighting and Appliance PanelsThe size of mains and branches should be selected based on the following:

■ Lighting and distribution circuits: NEC Article 210, 215, 220 and 240.

■ Motor circuits: NEC Article 430.■ Diversity factor.■ Provision for future loading.

Exception Number 1: Individual pro-tection for a lighting and appliance panelboard is not required when the panelboard feeder has overcurrent protection not greater than that of the panelboard.

Exception Number 2: For existing installations, individual protection for lighting and appliance branch circuit panelboards is not required where such panelboards are used as service equipment in supplying an individual residential occupancy and where any bus supplying 15 or 20 ampere circuits is protected on the supply side by an overcurrent device.

Ambient TemperaturesThe primary function of an overcurrent device is to protect the conductor and its insulation against overheating. In selecting the size of the devices and conductors, consideration should be given to the ambient temperature sur-rounding the conductors within and external to the panelboard. Cumula-tive heating within the panelboard may cause premature operation of the overcurrent protective devices.

Underwriters Laboratories test procedures are based, in part, on 80% loading of panelboard branch circuit devices. The NEC limits the loading of overcurrent devices in panelboards to 80% of rating where in normal opera-tion the load will continue for three hours or more. Further derating may be required, depending on such factors as ambient temperature, duty cycle, frequency or altitude.

Exception: There is one exception to this rule in both UL and NEC. It applies to assemblies and overcurrent devices which have been approved for contin-uous duty at 100% of its rating.

Special ConditionsStandard panelboards, assembled with standard components, are ade-quate for most applications. However, special consideration should be given to those required for application under special conditions such as:

■ Excessive vibration or shock.■ Frequencies above 60 cycles.■ Altitudes above 6600 feet (2011.7 m).■ Damp environment (possible fungus

growth).■ Compliance with federal, state

and municipal electrical codes and standards.

Seismic ConsiderationsThe Uniform Building CodeT and the International Building Code 2003, as well as local and state building codes, place an emphasis on seismic building design requirements. Electrical distribution systems are treated as attachments to the building and therefore, fall into this category.

All Eaton’s Cutler-Hammer panel-boards are seismic qualified at the highest possible level, Seismic Zone 4, and have been tested in accordance with ANSI C37.81. This standard quan-tifies actual earthquake conditions, as well as equipment seismic capability.

Harmonic CurrentsStandard panelboard neutrals are rated for 100% of the panelboard current. However, since harmonic currents can cause overheated neutrals, an option is provided for neutrals to be rated at 200% (1200 ampere maximum neutral for 600 ampere main bus) of the panelboard phase current.

Panelboards with the 200% rated neutral are UL listed as suitable for use with non-linear loads.

Prior to specifying the 200% rated neutral, Eaton recommends a harmonic survey be conducted of the distribution system, be it new or existing.

Transient Voltage Surge SuppressionThe quality of power feeding sensitive electronic loads is critical to the reliable operation of any facility. In modern offices, hospitals, and manufacturing facilities, the most frequent causes of microprocessor-based equipment downtime and damage are voltage transients and electrical noise.

Electrical loads and microprocessor-based equipment are highly susceptible to both high and low energy transients. High energy transients include lightning induced surges and power company switching. These high energy transients can destroy components instantly.

More frequently the electrical system experiences low energy transients and high frequency noise.

The effects of continual low energy transients and high frequency noise can cause erratic equipment perfor-mance or sudden failure of electronic circuit board components.

Eaton can provide protective and diag-nostic systems integral to panelboards. The Clipper Power System Visor Series is integrated into the panelboards using a “zero lead length” direct bus bar connection.

Pow-R-Line 4

The CPS Visor Series provides Transient Voltage Surge Suppression (TVSS) and active hybrid filtering. The CPS protects sensitive electronic equipment from the damaging effects of high and low energy transients, as well as high frequency noise.

Standards and CertificationsEaton’s Cutler-Hammer panelboards are designed to meet the following applicable industry standards, except where noted:

■ Underwriters Laboratories:❑ Panelboards: UL 67❑ Cabinets and Boxes: UL 50

Note: Only panelboards containing UL listed devices can be UL labeled.

■ National Electrical Code.■ NEMAT Standards: PB 1.■ Federal Specification W-P-115c:

Selection GuideTable 14-1. Panelboard Selection Guide

Terminal Wire Ranges, Pressure-TypeAl/Cu Terminals Except as NotedNote: All terminal sizes are based on wire ampacities corresponding to those shown in NEC Table 310-16 under the 75°C insulation columns (75°C wire). The use of smaller size, (in circular mills), regardless of insulation temperature rating, is not permitted.

Where copper-aluminum terminals are supplied on designated panelboard types, best results are obtained if a suitable joint compound is applied when aluminum conductors are used.

Check Eaton’s Cutler-Hammer standard terminal sizes versus customer requirements. In particular, 400 and

800 ampere breakers often require nonstandard lugs.

Optional 750 kcmil mechanical screw-type terminals are available upon request. Panelboard dimensions may be affected, refer to Eaton.

Series Rated CombinationsUnderwriters Laboratories permits panelboards to be labeled with a short circuit rating of up to 200,000 amperes (symmetrical) where UL listed combi-nations of main and branch circuit breakers are used.

These combinations consist of main breakers or fusible devices connected ahead of, and in series with approved conventional breakers used as branch devices.

Two arrangements are acceptable and comply with UL standards for panel-boards. The main circuit breaker or fusible switch may be installed in the panel as a main device, or it may be mounted remote, (directly upstream) from the panel. In either case, the approved main and branch combina-tions must be followed. These arrangements are acceptable and are UL listed having been tested in accordance with UL 67 standards.

From the tables that follow, specific combinations of main devices (upstream) and branch devices (downstream), series connected and electrically adjacent in the system, may be selected to qualify the assembled panelboard for the short circuit ratings shown.

Applying Series RatingsThe following is provided to use the series rating tables on the following pages.

1. Determine the available system voltage and fault current.

2. Select the appropriate table using the system voltage.

3. Use the appropriate “Series Equipment Rating” column equal to, or greater than, the available fault current, to determine the allowable UL recognized combina-tions of main (upstream) and branch (downstream) overcurrent devices. Main devices are shown in bold/shaded areas. Respective branch breakers are shown directly below their associated main device. If a rating is not initially found in a column, first look to the columns to the right for higher “Series Equipment Ratings“ within the same table. If still not found, use ratings from table of a higher system voltage (higher numbered table(s).
