## Episode 17 – How Circuit Breakers And Electrical Panels Work

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. ...

## Episode 16 – THEORY – Electric Current (Amperes/Amps)

Electric current is one of the hardest things to wrap your head around when you're first getting into the electrical trade.  Many apprentice electricians get confused with the difference between current and amps.  Well, that's because people talk about electrons and charges and interchange the terms without really knowing what the difference...

## Episode 15 – SCHEMATICS – Automatic Circuits (Contactors, Relays, Photocells, & Timeclocks)

Automatic circuits work on the philosophy that some external/automatic switch turns power on and off to a circuit.  This can be a photocell or timeclock that controls a set of relays or contactors which allow or disallow current to flow in a circuit.

## Episode 14 – Difference Of Potential (Voltage)

In order for electricity to work, there has to be movement. Static electricity still needs movement to occur in order to discharge and equalize charges. The only way that movement becomes useful is once there is a difference of potential present. That is what voltage is all about.

## Episode 13 – SCHEMATICS – How A Switch Loop Works

For those of us that are more visual learners, I've made this show one that can be followed visually.  In this episode I draw out on the white-board how switch loops work, and how to wire them.

## Episode 12 – How To Wire A Switch Loop

This episode is something a lot of green apprentices need to watch.  Switch-loops are very difficult to grasp when you're new to the trade, and in this show I break down how to install and wire for these bad boys.

## Episode 11 – SCHEMATICS – How 3-way and 4-way Switches Work

This episode goes further in depth on how 3-way and 4-way switches work. This is for those visual learners out there that need the logic drawn out so they can see the whole circuit in front of them.

## Episode 10 – What’s Inside A 3-way and 4-way Switch?

In this episode I take apart a 3-way and 4-way switch and talk about how they work on the inside

## Episode 9 – What’s Inside A Breaker (How Do Electrical Breakers Work?)

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.

## Episode 8 – How To Wire And Install 4-Way Switches

In this video I talk about how to wire for and install 4-way switches.  4-ways are very similar to 3-ways, and in fact you use (2) 3-way switches in a 4-way setup.
