How to Reset a Tripped Circuit Breaker

 · Fuse boxes operate similarly to breakers but require a different process to restore the circuit if a fuse "blows." Once you have located the main circuit breaker box, open the metal door and look for a bank of switches arranged in rows. There may be different types of circuit breakers in the box, but all operate the same way.
