Electrician School

Nobody qualifies as an electrician without lots of theoretical learning. Enrolling in electrician school is not a full-time decision: you will be learning in the field as an apprentice too. But don't be fooled: book learning is unavoidable. You're going to have to take exams too.

Basic Electrical Circuits

Circuit diagrams are a critical part of an electrician’s work. You’ll need to be able to read basic electrical diagrams. (You probably remember these from high school physics classes.) They look weird at first, but with some experience you’ll quickly master the art of reading them.

Parallel Circuits

Electric Circuit Breaker

You've interacted with circuit breakers many times in everyday life. They're in most modern bathrooms, and all homes have circuit breaker panels controlling the flow of electricity into areas of the house or apartment. What do you need to know about circuit breakers to be a better spark?

Electrical Generators

When there is no reliable source of power, or during an outage, generators will be necessary to keep the juice flowing. You may have used, or seen a friend or relative use, a generator on a camping trip, or up at a cabin. How do generators work, and how should they be used?

Wind Energy Generators

Green Energy Solutions

Putting green energy solutions to work saves you money and saves the planet for future generations. Making these changes isn’t difficult, but it may take a little getting used to. The more you practice a green way of life, the easier it will become.
