10.8.2.2 DESIGN AND CONSTRUCTION

A circuit operating at 50 V or less shall be treated as a hazardous circuit if the power in it can

create electrical shocks, burns, or an explosion due to electric arcs. Observe all of the following

rules for such circuits:

1. Provide protective covers and/or barriers over terminals and other live parts to protect

personnel.

2. By suitable marking, identify the hazard at the power source and at appropriate places.
