There are two types of standard circuit breakers: Single Pole - Single pole breakers protect one energized wire and supply 120V to a circuit. These are the most common types of breakers in homes, but they are also used in small businesses. Double Pole - Double pole breakers protect two wires at the same time and occupy two slots in a breaker panel.

Aside from the breaker box and panelboards, you may also consider the type of breaker. The most common breaker you may see in a typical home is

Inside, look for the name Stab-Loc (the brand name of the circuit breakers). Zinsco Panels Zinsco or GTE-Sylvania panels were popular electrical panels installed in homes throughout the 1970s. Zinsco is now defunct, but many homes still have these panels. Why they’re unsafe: The circuit breakers inside many Zinsco panels melt to the main ‘bus bar’.

Dec 19,  · The very first circuit breaker was devised in 1879 by Thomas Edison, when he came up with the idea of protecting circuit wiring used for lighting from the common problems of current overloads and short circuits. Of course, we now know that his system suffered from the fatal flaw of using fuses that would need to be constantly replaced.

Bryant Electrical Panel Age, History, Circuit Breaker Performance If your panel includes residential-type circuit breakers that look as old as the panel 

NOTE: Beginning in the 1960s, fuse boxes were phased out in favor of electrical systems controlled by circuit breakers. It's important to replace an old fuse 

The Air blast circuit breaker employs a high-pressure air blast as an arc extinguishing medium. This type of circuit breaker is used in open terminal HV applications with a voltage range of 245 kV, and 400 kV up to 765 kV, especially where fast breaker operation is required. Compared to SF 6 and vacuum type, air blast circuit breaker is rarely
