Wire and Wiring Connections

Electric Pro Academy - Real Skills to make real money.

Synopsis:
One of the primary jobs of an electrician is wire selection. Insufficient wire threatens heat-related failure and excessive wire threatens inflexibility and financial burdening to the business & customer. In this video, Joel has rounded up a warehouse-worth of wire and wire connectors to share his experience with each, including naming systems, code references, relevant slang terms, & best practices employed daily by Jefferson Electric masters, journeymen, & apprentices.
