Circuit Breakers, USA. Question

Recommended Posts

The most commonly found 110v breakers are either 15a or 20a in normal houshold panels. You can get 30 and even 50 amp 110v breakers. It really depends on what you are planning on powering up with that 110v.

Never look down on someone, unless they are going down on you.

In the USA all electrical equipment is usually rated at 120 vts. Some light bulbs have a 130 vt. rating.
We all know what (electrician) is meant by 110.

120/240 or 110/220 and in some cases 115/130

Square D brand makes breakers in 10 amp ratings also. The single 30 and 50 amp breakers are for RV hook ups etc......I can imagine much other equipment rated at 30 or 50 that isn't 240 vts.:)
