My in laws recently moved into an older home. Not sure when it was built, but the house does contain such things as T slot receptacles and it even still has a fuse box.

The fuse box, made by Murray, has 4 30 amp fuses in it, and also has these bakelite looking things with handles on them. It has 3 of those, 2 of them sit above the fuses and the other one is slightly bigger that sort of sits off to the side.

I haven't seen a fuse boxin so many years that was still powering a home. Anyone know what was the lastyear they used fuse boxes in american residences?

Thanks in advance.
