• Canada’s model Code for electrical safety

• Covers installation and maintenance of all electrical equipment

• Primary purpose:  prevention of fire and electric shock

• First edition published in 1927

• Next edition (24th) to be published in Jan. 2018

Who is responsible for electrical safety?

• Each Province• Each Territory

* Federal government responsible for areas under Federal jurisdiction.

Code Adoption - Goals

• within 6 months of publication

• with as few Provincial and Territorial amendments

as possible

3. Power over Ethernet –the Paradigm Shift

Power over Ethernet

… the capability to deliver 42-57 VDC over the same copper cable used currently for Ethernet networks.

22

So, just what is Power over Ethernet

… and requires at least 2 main elements:

- Power sourcing equipment (PSE)

- Powered device (PD)

… and in some cases requires a

- Power injector (PI)

… cable?

Ethernet

… is a family of computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN).

23

So, just what is Power over Ethernet …cable?

• Commercially introduced in 1980 • First standardized in 1983 as IEEE 802.3, • Original 10BASE5 Ethernet -> coaxial cable • Newer Ethernet variants -> twisted pair and

… fiber optic links in conjunction with hubs or switches.

2003 IEEE 802.3af 15 W2009 IEEE 802.3at 30 W2017 TBD IEEE 802.3bt (under development) 95 W

Do benefits overcome drawbacks?

24

• Energy savings

• Flexibility

• Cost Savings

• Ability to measure and report performance

• Flicker• Cybersecurity • Interoperability• Glare• Electronic noise

• Voltage drop• Heat generation • Configuration complexity

How complex is …“complex”…?

4. CE Code Part I –Proposed Changes

Timeline

27

• September 2016 - Task Force (CSA + Industry) – drafting the CEC Part I proposals to allow installation of Limited

Power (LP) equipment (a.k.a. PoE).

• Dec 2016 - Proposal submitted to TSC on Section 16 – Review concluded with 5 negative votes. They were all resolved.

• March 2017 - Subject 4168 issued for Part I committee ballot

Low Voltage Lighting Systems

C22.2 No. 250.2 (under development) Proposed ScopeThis Standard applies to lighting systems equipment, either factory or field-assembled, designed to be used in non-hazardous locations, which may be smart enabled, designed to control various loads (such as CFLs, LEDs, Tungsten-halogen lamps, motors, receptacles etc.) for commercial, industrial or residential applications and intended to be installed in accordance with the rules of the Canadian Electrical Code Part I, C22.2 No.1.

These requirements cover:a) Controls and Power Source Equipment limited to voltage levels below the risk of electric shockb) PoE and other extra low-voltage and low-voltage luminaires and lighting systems equipment. c) Interconnection with building management and control systems (such as HVAC, security, A/V etc…).
