The Ontario Electrical Safety Code is a regulation that applies to all types of electrical installations. Unavoid-ably, it is sometimes written in a general fashion.

If the design of the equipment allows the draw-out parts to be in the connected, test, or fully disconnected position without opening the cell door, then no additional space shall be required for equipment draw-out and the measurements required by Rules 2-308 and 2-310 can be measured from the front face of the equipment.

2. For equipments rated 1200A and higher or over 750V, Rule 2-310(2) requires the minimum working space about electrical equipment mentioned in Rule 2-308(1) to be increased from 1 m to 1.5 m if a person in-side an electrical room or the space around electrical equipment can NOT leave the space without pass-ing a potential failure point on path to exit.

Where space is restricted and the working space cannot be increased to 1.5 m, as mentioned in Appendix B, then a second exit (or more if needed) in the room in different locations shall be provided such that an individual can leave the space without passing a potential failure point on path to exit.

Question 5When switchboard is used as service entrance equipment, what are the OESC minimum requirements for the KHDGURRPFOHDUDQFH",VLWPDVSHU5XOHRUPDVSHU5XOH"

Answer 5OESC requires the headroom clearance to be at least 2 m for consumers service equipment (as per Subrule 6-206(1)(c)). However, if that service equipment is a switchboard, where bare live parts are exposed at any time, then Subrule 2-308(4) shall apply and a headroom of 2.2 m is the minimum required.

Answer 6This is interpreted as meaning a space that is at least 1 m in depth in front of the panel and at least 1 m in width or the width of the panelboard, whichever is greater. In addition, OESC requires the headroom clear-ance to be at least 2 m for consumers service equipment (as per Subrule 6-206(1)(c)).

Subrule 2-310(1) requires that each room or space containing electrical equipment (such as transformers, overcurrent devices, switchgear, disconnecting means, panelboards, etc.) to have unobstructed means of egress in compliance with Ontario Building code (OBC). The purpose of this rule is to ensure that personnel have ready means of exit from an electrical room in case of an accident.

OBC requires a minimum width of 750 mm with no obstruction for egress means (OBC Articles 3.3.1.22 and 9.9.5.4.). Also, Rule 2-312 requires that passageway (exit path) and working space around electrical equip-ment to be kept clear of obstruction as shown in Figure B3.

Bulletin 2-10-7(OHFWULFDOHTXLSPHQWQHDUFRPEXVWLEOHJDVHTXLSPHQW

Rule 2-322Issued January 2010


Rule 2-322 states that arc producing electrical equipment shall not be installed within 1 metre of the discharge of a combustible gas relief device or vent.

4XHVWLRQVKDYHEHHQDVNHGUHJDUGLQJWKHVSHFLFW\SHVRIHOHFWULFDOHTXLSPHQWFRYHUHGE\WKHUXOH

The electrical equipment includes, but is not limited to, receptacles and switches, an air conditioning unit and related disconnecting means (which must be located within 3 m of the AC unit as per Rule 28-604(5)). This interpretation is consistent with the rules concerning the use of electrical equipment in Class 1 Zone 2 loca-tions.

Permanently installed electric metering equipment (other than metering equipment with integral internal con-tacts for recording or remote reading) is permitted to be located within 1 metre of the combustible gas relief vent.

Figures B1 & B2 illustrate two examples of installations that comply with the minimum requirements.

Figure B1

Figure B2




Question:Is it permitted to install arc producing electrical equipment (e.g. a/c unit) at a distance of less than 1 metre from the discharge of an approved Over Pressure Cut-Off (OPCO) combustible natural gas relief device or vent?

Answer:Yes, if an approved Limited Relief OPCO device is installed, arcing electrical devices may be installed no closer than 0.3m (12 inches) from the point of release. The over pressure relief device must be marked LR-OPCO (see the example in the photo).

Background:Under CSA standard B149.1S1.07 section 5.5.9, the clearances from relief devices installed outdoors are listed in Table 5.2. For Natural gas CSA 6.18 certified OPCO (overpressure cut-off) regulators with limited relief of (1.5m3/h) or less, the clearance from a source of ignition is 0.3m.

Page 2 of 3




On residential sites where there is very little space to locate the A/C unit and natural gas vent at 1 metre separation, the use of a natural gas certified OPCO regulator is an acceptable solution to the problem of separation. This may also be applied where there is an outdoor receptacle located at a distance of less than 1 metre from the vent.

In the event that a metal pole is struck by lightning the discharge of energy would be dissipated into the mass of the earth through the #6 bond conductor loop and associated ground electrodes, there by protecting the control equipment located in the controller cabinet.

This bond path and method of installation is acceptable and will allow all overcurrent devices to operate under fault conditions.

Cables and conductors shall be of types suitable for exposure to the weather as listed in Table 19 and ap-proved for this type of installation. Additionally, cables and conductors shall be marked for sunlight resistance (SR or SUNLIGHT RESISTANCE) where installed and used subject to direct rays of sun, as per Rule 2-130.

For example, Rule 30-1102 permits Types RW75, R90, RW90, TW, TWU, TW75, and TWU75 conductors to be lashed to a messenger cable for outdoor lighting where exposed to the weather. Type RWU conductorsshall also be permitted, although not listed in Table 19.

If the information is missing, incomplete or inaccurate, the inspector may be forced to make assumptions as to whether the site visited is indeed the intended target of the request for inspection.

This can create confusion, errors and potential safety issues. When an inspector issues a connection authori-zation to energize a service, the Local Distribution Company (supply authority) uses that same location infor-PDWLRQZKHQHQHUJL]LQJWKHVHUYLFH,IWKHLQVWDOODWLRQLVQRWFOHDUO\LGHQWLHGWKHZURQJVHUYLFHPD\EHFRPHenergized, with serious consequences.

Rule 2-034 ,VVXHG0D\


IssueQuestions have been asked regarding acceptable brands and types of new circuit breakers for use in older brand names of panelboards that are no longer manufactured.

BackgroundThere have been several issues with respect to replacing breakers in panels where the panel board manu-facturer is no longer in existence or has been acquired by another manufacturer. In consultation with various manufacturers, Table B1 was constructed to provide breaker replacement information for the various panel-boards used in the province of Ontario. Table B2 has been provided by Cutler Hammer as a more compre-hensive cross reference regarding breakers that they currently manufacture under the Cutler Hammer brand name that are compatible with panelboards having older brand names.

DirectionAll panelboards are required by the product standards to be marked with the make and type of breakers that are acceptable for use in that panelboard. A replacement breaker is permitted to be of a different brand name than the original panelboard provided that it is the same type as one of those marked on the panel. The circuit EUHDNHUPXVWDOVREHDUDUHFRJQL]HGFHUWLFDWLRQPDUN$VDQH[DPSOH7\SH4%/EUHDNHUVWKDWDUHFXUUHQWO\manufactured under the Cutler Hammer brand name are permitted to be installed in older C.E.B., Sylvania, and Commander brands of panels that are marked for use with this type of breaker.
