Part 40 Utility Workers – Electrical

Explanation of Rules Referenced from the ECUC, Second Edition

Rule 4-182 Work from uninsulated surface

Subrule 4-182(1) exempts a qualified utility employee from having to perform rubber glove work from a rated insulated device (as required by subrule 4-180(c)) if the electrical equipment or lines operate at a voltage less than 5 kilovolts between conductors. As long as this voltage limit is not exceeded, work can be performed from a non-insulated surface such as a dry wooden pole which is not likely to conduct electricity.

If work is done in this way, subrule 4-182(2) requires that, as specified in rule 4-142, the worker must maintain a limit of approach distance of

(a) 150 mm between unprotected body parts and the exposed energized phase being worked on, and
(b) 500 mm between unprotected body parts and exposed adjacent phases or exposed grounded parts.
