What Dale said is one consideration, and another is to check to make sure your wiring is properly grounded. There are two common ways to ground wiring: one is to run the ground wire to iron plumbing (it does act as a ground because the pipe goes into the earth, but may not always be efficient enough to prevent shorting) and the other, code-correct way, is to drive an iron stake into the ground outside of your home close to your circuit box and run multiple copper wires to that. If you have one, you can't miss it; it's a stake with a bundle of wire running to it, right by your foundation. If you don't, you may want to have your electrician put one in; it's not expensive.

Another possibility is a short-circuit somewhere in your electrical system, such as a loose wire touching conduit. Your electrician should be able to find something like this fairly easily, if that is the case.
