Yes. #8 is a oversized by one size but it's total ok. You can always oversize on electric wire but never undersize.
If you are referring to house wiring then the answer is no. A breaker protects the wire size that is connected to the breaker. In home wiring most homes are wired with a #14 wire which is rated at 15 amps. That is why the wire is protected by a 15 amp breaker. The correct wire size to connect to a 40 amp breaker is a #8. This size wire is too large to connect to receptacles an light fixture terminals.
A 40 amp breaker is used in conjunction with AWG # 8 copper wire. The black and red wires are connected to the breaker. The ground wire is connected to the ground bar and the white wire is connected to the neutral bar.
A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
A #8 aluminium wire with an insulation factor of 90 degrees C is rated at 45 amps.
The recommended wire size for a 40 amp breaker is typically 8 AWG (American Wire Gauge).
The appropriate wire size for a 40 amp breaker is typically 8 AWG (American Wire Gauge).
The recommended wire size for a 35 amp breaker is typically 8 AWG (American Wire Gauge) for copper wire.
For a 40 amp breaker, a wire size of at least 8 AWG (American Wire Gauge) should be used to ensure safe and proper electrical conductivity.
No, you should not run 8 gauge wire on a 50 amp breaker. The wire size should be compatible with the amperage rating of the breaker to ensure safety and prevent overheating. For a 50 amp breaker, you should use a minimum of 6 gauge wire.
For a 40 amp breaker, a 8-gauge wire should be used to ensure safe and efficient electrical flow.

For 28 amps, you would typically use a wire size of at least 10 AWG (American Wire Gauge) for copper wire. This would ensure that the wire can safely carry the current without overheating. It's always a good idea to consult a professional electrician or refer to local electrical codes to determine the appropriate wire size for your specific application.
For a stove, use a 8 or 6 gauge wire with a 40 to 50 amp breaker. For a dryer, use a 10 or 8 gauge wire with a 30 amp breaker. For a hot water heater, use a 10 or 8 gauge wire with a 30 or 40 amp breaker. Be sure to consult local electrical codes and guidelines for specific requirements.
AWG # 8 copper
The appropriate wire gauge size for a 40 amp circuit is typically 8 AWG (American Wire Gauge).
No, you cannot use an existing 8 3 wire hooked to a 30amp breaker for a heater that requires 10 2 wire. The wire gauge and breaker size need to match the specific requirements of the new heater to ensure safety and proper function. You will need to upgrade the wiring to accommodate the 10 2 wire needed for the 5000-watt 240-volt heater.
