A circuit breaker is the only reusable circuit protector in that list.
A fuse is also circuit protection, but it is not reusable.
A length of wire can work like a fuse in some applications, such as feeding Transformers on poles, but the wire would have to be small enough of a gauge to be able to burn out when overloaded. However, the wire would need replaced after an overload.
A three prong outlet is for protecting humans, not circuits. The ground wire is for providing a low impedance fault current path back to the breaker to trip the faulted circuit's breaker (or fuse). The opening of the circuit will prevent a possible fire. However, a three prong outlet doesn't actually provide the protection of tripping the circuit.
The minimum size equipment grounding conductor required by the NEC for a branch circuit protected by a 50-ampere rated circuit breaker is 10 AWG copper or 8 AWG aluminum.
The size of the ground wire for a circuit is typically based on the size of the circuit breaker protecting that circuit. For a 200 amp circuit breaker, the recommended ground wire size is 4/0 AWG (American Wire Gauge) copper wire. This wire size helps ensure that the ground wire can safely carry any fault currents that may occur in the electrical system.
That would be a 40 amp 220v circuit. Circuit breaker is 40 amps and wire is 8 awg. Should use solid copper wire. Follow oven installation instructions.
For a 100A circuit breaker, you typically need a wire size of #2 AWG (American Wire Gauge) for copper conductors or #1/0 AWG for aluminum conductors. It is important to consult the National Electrical Code (NEC) or a qualified electrician to determine the appropriate wire size for your specific installation.
Yes, a 20 amp breaker requires AWG # 12 copper wire. A 15 amp breaker requires AWG # 14 copper wire.
The minimum size equipment grounding conductor required by the NEC for a branch circuit protected by a 50-ampere rated circuit breaker is 10 AWG copper or 8 AWG aluminum.
The NEC requires that if the intended rating of a circuit corresponds to a standard size breaker then that size breaker must be used. In most instances, "rating of a circuit" means the intended connected load plus 25%. If the intended rating of a circuit does not correspond to a standard size breaker, you can go up to the next standard size without any other adjustments. In most circumstances, besides what I've already stated, a 14 gauge copper wire cannot be connected to a breaker larger than 15 amps, 12 gauge copper to a 20 amp breaker, and 10 gauge copper to a 30 amp breaker.
AWG 2/0 copper wire.
Typical residential electric dryers are on 30 amp circuits, which means 10 gage copper wire. The circuit breaker should match the dryer cord rating, generally 30 amps.
Hmm...is this a question i must know?
A #8 copper conductor with a 90 degree C insulation factor is rated at 40 amps.

No. The two appliances usually have dedicated circuits. The range will have a two pole 40 amp breaker and be fed with a 3-C #8 copper cable. The dryer will have a 30 amp two pole breaker and be fed with a 3-C # 10 copper cable. As you can see by powering a 40 amp device from a 30 amp breaker, full operation of the range will trip the 30 amp breaker.
120 amps The above answer is wrong. A 60 amp breaker is designed to trip at 60 amps be it a single pole, double pole or a triple pole that is used on three phase equipment. The number on the handle of a breaker is the trip capacity.
