If you are contemplating a major remodel, the addition of a room or garage, or a new kitchen you should consider upgrading your electrical service.
Thirty years ago, the average new home was equipped with a 60 amp electrical service connected to a screw-in fuse panel with two fuse blocks. The common distribution was a fuse block for the stove and one for the hot water tank. The balance of the homes electrical needs were served by six, 15amp screw-in fuses.
Twenty years ago the average new home was equipped with a 100 amp electrical service and some of them used the latest in technology, circuit breakers.
