About this course

Wondering how residential wiring works?  In our series "Residential Wiring: From Utility to Home Loads", we'll walk you through the practical skills and the concepts of electrical wiring, from the utility transformer all the way to the lights and appliances in a home.  We'll go through wiring up a meter enclosure and the "guts" of a service panel-- service entrance conductors, grounding electrodes, and branch circuit wiring.  We'll also give you a healthy dose of electrical theory and code references as they pertain to residential installations.
