Draft Scope/Description:
This standard applies to Electrical Energy Regulating Equipment (EERE) designed to monitor the consumer’s service, feeders, and branch circuits and control the connected loads so that connected loads do not exceed the rating of the existing consumer service, feeders and branch circuits, rated 1000V or less, in compliance with the Canadian Electrical Code, Part I (CE Code, Part I).
