This question has been asked by so many people over such a long time. Why on earth do we have to bond the system neutral and the equipment grounding conductors, and grounding electrode conductors in an electrical system?
The term electrical power is often misused and thrown around incorrectly. Power really means “work done.” Electrical Power means, work done by electricity. We use several different terms when discussing electrical power, and it can get confusing which one we’re talking about from time to time. So what is a Watt? A watt is...
This Video is Sponsored By Connecticut Electric What is a CB? Circuit breakers are safety devices that stop the flow of electricity when it’s specifically rated parameters are passed. These can come in a few forms, the first is an Overcurrent Protection Device or OCPD, which you can learn all about in Article 240...
Surge Protection. Why, where, and wtf NEC 2020 code requirement changes The National Electric Code (NEC) sets the standard for electricians and electrical work across the US, with the arrival of it’s 2020 edition adding some substantial changes to the codes on surge protection. The most notable of these changes can be...
A lot of green apprentice electricians ask about how panels work, and more specifically what the roll of the circuit breaker is. Some guys think that breakers “put out” electricity, or that they “send” a certain amount of amperage to a load from the panel. This is not how it works. To start out,...
This episode is all about breakers, from the outside-in. I cover the differences between single-pole, two-pole, and 3-pole breakers. I talk about how a breaker is a simple spring-held mechanical switch that operates by an internal electromagnet. Finally I take a Square D single-pole breaker apart and show you how a breaker trips, and...
In this episode I take apart a standard receptacle and a decor switch and show what is inside. I show how a plug is really just small pieces of metal that are electrically conductive. I also talk about how you can run separate circuits to a plug by cutting the tab between the terminals....
If you ever get into the commercial service side of the electrical industry, you’ll most likely come across SMART BREAKERS. In this episode, we talk about what smart breakers are and how they work.

A transfer switch is a device that is used to switch back and forth between two different power supplies. Most of the time one source is the utility company (the grid), and the other is for a backup generator in the event utility power fails.

Contactors are heavy-duty electromagnetic switches that are normally used in controlling large lighting loads and motors. They operate similar to relays, but often times deal with more voltage, higher amperage, and have more input and output options. CONTACTORS Contactors are extremely useful pieces of equipment that allow switching of several different circuits at the...
