This Technical Information Letter (T.I.L.) applies to DC arc-fault protective-devices (DC-AFPDs) and devices incorporating arc-fault circuit protection intended for use in direct current circuits having a maximum voltage rating of 1000V. A DC-AFPD is intended to detect and mitigate the effects of arcing faults, which may pose a risk of fire ignition under certain conditions if the arcing persists…

This Technical Information Letter is based on CSA Standard C22.2 No. 182.3 ?Special use attachment plugs, receptacles, and connectors.? Basic requirements for special use connectors contained in the standard have been supplemented with additional construction and test clauses to address harsh environmental conditions expected during the intended usage of the connectors in photovoltaic systems.

These requirements apply to assemblies of resistors, enclosures, and other components to provide high impedance grounding for the purpose of controlling the ground fault current or the voltage to ground of an alternating current system, when installed in accordance with the Canadian Electrical Code, Part I.

This Technical Information Letter (T.I.L.) has been prepared to offer an alternative path to calculate annual energy consumption (AEC), adjusted volume (AV) of household refrigerators, refrigerator-freezers and freezers if manufacturers choose to use the new US DOE test procedure (10 CFR Part 430 Subpart B Appendix A and Appendix B) instead of CAN/CSA C300-08. Manufacturers have the option of…

This Technical Information Letter specifies the requirements for distribution (power), control and signal cables intended for installation aboard commercial ships and mobile offshore drilling units in accordance with recommended industry practice and the regulations of authorities having jurisdictions (AHJ). These installations are outside the scope of the Canadian Electrical Code (CEC). However…
