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.

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.

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.

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

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.

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.

Well everyone....the time is here! I'm in New York City for this year's #THDProSpective tool event and I'm about to find out what tool manufacturers will be sending me over the next year to test, review, and give away!

In this episode I talk about how to wire and install 3 way switches and California (illegal or dead-end) 3ways.

In this episode I rip open a standard receptacle and a decor single-pole switch to reveal how each of these electrical devices works.
