Can I use a 40 amp breaker for a 30 amp?
A 30-amp circuit uses wiring that can only handle 30 Amps of electricity, which means anything over 30 Amps flowing through that circuit will cause the wires to heat up. A 40-amp breaker could potentially allow unsafe levels of electricity to travel through that circuit and never trip until the flow reaches 40 Amps.
What does the R mean on A fuse?
What does H stand for on a fuse?
