You can find your plug fuses in a centrally located fuse box. For safety’s sake, keep the fuse box closed and make sure that all the fuses are in place; do not leave a fuse spot open. In addition, make sure that the fuse box and wiring remain completely dry.
If your fuse box is not already labeled, tape a piece of paper inside the fuse box that identifies the items or rooms in your house protected by each fuse. If you label your fuse box, you will have a much easier time replacing a blown fuse. In addition, near your fuse box, you should keep a few extra fuses. One extra fuse of each type of plug fuse that you need is probably adequate.
Your cartridge fuses are probably in a fuse block. A fuse block is similar to a fuse box, but it protects the main electrical circuit in your building and possibly a few large electrical items, such as an electric stove, as well. The fuse block is often near or within the larger fuse box.
The best way to protect your fuses is to be careful not to overload the circuit. Find out how many amps and volts your circuits can carry, and keep an eye on what items you are running. Use common sense, and don’t run a hair dryer, space heater, and toaster out of the same wall outlet.
