Regulatory Landscape Who is responsible for electrical safety? Each Province Each Territory * Federal government responsible for areas under Federal jurisdiction. 19
Code Adoption - Goals within 6 months of publication with as few Provincial and Territorial amendments as possible As of May 2017 2015 2012 20
3. Power over Ethernet the Paradigm Shift
Power over Ethernet So, just what is Power over Ethernet cable? the capability to deliver 42-57 VDC over the same copper cable used currently for Ethernet networks. and requires at least 2 main elements: - Power sourcing equipment (PSE) - Powered device (PD) and in some cases requires a - Power injector (PI) 22
Ethernet So, just what is Power over Ethernet cable? is a family of computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). 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 W 2009 IEEE 802.3at 30 W 2017 TBD IEEE 802.3bt (under development) 95 W 23

4. CE Code Part I Proposed Changes
Timeline September 2016 - Task Force (CSA + Industry) drafting the CEC Part I proposals to allow installation of Limited Power (LP) equipment (a.k.a. PoE). Nexans Comtraining Philips IAEI ESA Ontario Berk Tek Deca Cables Inc BCIT CSA Group Electro Cables Inc Guild Electric Cisco 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 Approval Disapproval 33 4 27

5. Product Standards Proposed Updates
Product Standards Proposed Updates PSE (Power Sourcing Equipment) CABLE (Data & Power) PD (Powered Device) Binational (Canada / USA) C22.2 No. 214 (updates) CSA C22.2 No. 60950 Binational (Canada / USA) (Transition to 62368 1) CSA C22.2 No. 233 (updates) C22.2 No. 182.4 (updates) CSA C22.2 No. 250.2 (under development) 36
Power Supply Equipment 2 nd edition adopted in 2014. 3 rd edition at FDIS will include DC power transfer through information technology communication cabling CAN/CSA C22.2 NO. 60950 1 Information Technology Equipment Safety (Bi national) FUNDAMENTAL TRASITION CAN/CSA C22.2 NO. 62368 1 Audio/video, information and communication technology equipment (Bi national) Challenges those familiar with IEC 60950-1 to adopt the Hazard Based Safety principles in equipment design assess the potential impact of requirements in IEC 62368-1 on existing equipment which has been designed using IEC 60950-1. 37
Cable products 8 th edition published in March 2017 CSA C22.2 NO. 214 Communications cables (Bi national) Relevant Changes: New Clause 7.24 - Cable heating test for cables marked LP Marking for LP (xx) cables 38
Connectors C22.2 No. 233 - Cords and cord sets for communication systems Connectors: CSA C22.2 No. 233 (updates) C22.2 No. 182.4 (updates) NE published in June 2017 Scope change to include DC cords Marking for the DC type cords Similar update to C22.2 No. 182.4 - Plugs, Receptacles, and Connectors for Communication Systems Testing for DC connectors is fundamentally different Lengthier process - a new Annex is being developed for DC type connectors 39
Low Voltage Lighting Systems Seed document ready for TF review Jan. 2018 Expected Publication C22.2 No. 250.2 (under development) Proposed Scope This Standard applies to lighting systems equipment, either factory or fieldassembled, 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 shock b) 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 ). 40
