ULC 61229

This National Standard of Canada is applicable to protective covers used to cover live, dead, or adjacent earthed (grounded) parts in order to prevent contact with any electrical conductors, apparatus or circuits.

The use under d.c. conditions is not covered by this Standard.

A protective cover is only used to provide protection when a worker inadvertently comes into momentary contact with the protective cover, and the selection of the protective cover is based on the system operating voltage.
