Gives guidance on the protection of overvoltage issues for both stand-alone and grid-connected photovoltaic power generating systems.

Applies to control and protective switching devices (or equipment) (CPS), the main contacts of which are intended to be connected to circuits of rated voltage not exceeding 1 000 V a.c. or 1 500 V d.c. CPS are intended to provide both protective and control functions for remotely controlled circuits. They may also fulfil additional functions, such as isolation.

1. Scope 1.1 This Standard applies to clock-operated switches, rated 600 V or less, designed to be used in ordinary locations to close and open circuits to a load at predetermined intervals, and intended to be employed in accordance with the Rules of the Canadian Electrical Code, Part I. The clock-operated switches discussed in this Standard may be (a) completely enclosed, plug-in, or cord-…
