Fuses vs. Breakers

If you have a fuse box in your house that looks anything like the picture to the left, I would recommend you have it upgraded to a breaker box. 

There are several reasons I say this:

1.It is old.
2.I can almost guarantee it is overloaded. Any house nowadays requires more circuits than the old fuses boxes hold.
3.It will increase your resale value.
4.Some homeowners insurance companies raise your rate, or even cancel your policy, 
if you have one. (it just happened to a customer of mine recently)
5.They are a known fire hazard, because people oversize the fuses, and the wires can get very hot, without blowing the fuse.
6.It is somewhat difficult to tell if a fuse is blown, compared to a breaker.
7.There is no room for new circuits, whereas a new panel could have 42 spots
(yours likely has less than 12).
8.When a breaker trips, you don't need to run out to the store and buy a new one. 
9.Looking at the face of the fuse panel, you can not tell what is the proper fuse size. The cover needs to be removed to determine wire size.
10.Changing fuses can occasionally be hazardous. I have been shocked when inserting a fuse, because it was wired backwards.

When your fuse panel is upgraded to a circuit breaker panel, it will look like the picture to the left.

When a circuit trips, due to overloading, or a short circuit, you simply find the breaker that is in the Middle position, turn it all the way off, and then back on again.

If it immediately trips again, I would call an electrician to locate the problem.
