The main function of a circuit breaker is to cut power to a circuit when it has too much current flowing through the wires of that circuit.
This can happen when several multiple outlets are added to a circuit through use of a power bar or surge protector making it possible to plug several appliances or components into one outlet.
I have been an electrician for almost 9 years and have over 9,000 hours of experience. I had a very secure position at my last job and with no warning I got cut from that place due to industry down sizing, thankfully I was already prepared to work from home and not need an employer. I am now living life on my own terms and would like to show you how to do the same.

A thyratron is a type of gas-filled tube used as a high-power electrical switch and controlled rectifier. Because of the gas fill, thyratrons can handle much greater currents than similar hard-vacuum tubes, since electron multiplication occurs in the ionized gas, the phenomenon called Townsend discharge. Gases used include mercury vapor, xenon, neon, and hydrogen. Unlike a vacuum tube, a thyratron cannot be used to amplify signals linearly.
In the 1920s, thyratrons were derived from early vacuum tubes such as the UV-200, which contained a small amount of argon gas to increase its sensitivity as a radio signal detector; and the German LRS Relay tube, which also contained argon gas. Gas rectifiers, which predated vacuum tubes, such as the argon-filled General Electric “Tungar bulb” and the Cooper-Hewitt mercury-pool rectifier, also provided an influence. Irving Langmuir and G. S. Meikle of GE are usually cited as the first investigators to study controlled rectification in gas tubes, about 1914. The first commercial thyratrons didn’t appear until around 1928.
