Electrical Panal Question


I am interested in running power to a garage area and to place three 30A outlets outside for plugging in our pop-up camper and for visiting friends that come down with their camper. A friend has given us a 125A rated electrical panal that was out side of their mobile home. But the main breaker in the box is only 100A. Can this be replaced in the panal to support three 30A and two 15A breakers? I am planning to place three 30A and two 15A breakers in the box (currently there is only the main breaker) but assuming that the individual breakers cannot exceed the size of the main breaker.

I do have an electrician helping in this but I like to find out information like this when he is not available to answer a question.

Thanks

The panel should be fine. You don't add up the breaker rating to determine power requirements.

Okay

Thanks...like I said I did not know. So what makes a 125A box different from say a 150 or 200?

The buss that carries the power is heavier on higher ampacity panels.
