Summary
This 54-minute video describes the basic layout of overhead distribution systems. It explains how to identify circuits and equipment in the field, and introduces delta- and wye-connected distribution systems. It shows the basic layout of an overhead distribution system and identifies circuits and equipment in the field. Covers the importance of identifying whether a system is connected delta or wye, before any work is performed.
