How to Change Fuse to a Circuit Breaker

Circuit breakers have protected the circuits of houses for several decades, but many older homes still use the old glass screw-in fuses. Replacing these fuses with circuit breakers was once a huge job, requiring that the entire fuse box be replaced. New miniature circuit breakers have changed that.

Things You'll Need

• Miniature circuit breakers

Instructions

1. Look at the old fuse to determine the amperage rating, which is printed on the top.

2. 

   Go to a home-supply or hardware store and purchase a screw-in minibreaker of the same rating. These are also available from online suppliers.

3. Unscrew the old glass fuse to remove it. Screw in the new minibreaker in the same fuse holder.

Tips & Warnings

• Use caution when working with electricity. Always replace a fuse with a new one of the same or lesser rating.
