What are fuses & circuit breakers?

Fuses and circuit breakers may also be installed in equipment such as your automobile to protect against internal faults. Figure 2–29 shows a variety of fuses and breakers. Fuses use a metallic element that melts when current exceeds a preset value. Thus, if a fuse is rated at 3 A, it will “blow” if more than 3 amps passes through it.

What are striker fuses?

Striker fuses are fuses fitted with a spring-loaded striking device that can trip adjacent switches and also indicate that a fuse has blown. A Type C fuse is actually a type of miniature circuit breaker (MCB). MCBs are a type of circuit breaker used with lower-powered circuits to cut off current in the event of an overload.

What is a Type C fuse?

A Type C fuse is actually a type of miniature circuit breaker (MCB). MCBs are a type of circuit breaker used with lower-powered circuits to cut off current in the event of an overload. Type C fuses trip circuits when the current exceeds the rated one by between five and ten times - i.e. at 100-500 amps for a 20amp device.

Can you install a circuit breaker in a fuse box?

You cannot install a circuit breaker inside a fuse box. The design of the enclosure is completely different. Some older fuse boxes may have a main breaker or main fuses. It really depends on the age of the box. A fuse panel can still be good but it can also be very difficult to add circuits to.
