No, it is not safe to use a #8 conductor on a 50 amp breaker. A #8 conductor is only rated at 45 amps capacity. By connecting it to a 50 amp breaker, which would trip at 50 amps on an overload, would overload the conductor by an extra 5 amps. This would be a conflict against the electrical code.

Can you use 10 gauge wire to connect a 2 15 amp outlets to a 30 amp breaker?

No, it is not safe to use 10 gauge wire with a 30 amp breaker as the wire is not rated for that high of a current. It is important to use the correct wire gauge that matches the breaker amperage to prevent overheating and potential fire hazards. For a 30 amp breaker, you should use at least 10 gauge wire.

Use a 30 amp breaker.


How big of breaker do you use for 115 volt?

Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.

No, it is not safe to use a 15 amp outlet on a 20 amp breaker as it can lead to overheating and potential fire hazards. It is important to match the outlet's amp rating with the breaker's amp rating for safety.


Is it safe to use a 20 amp outlet on a 15 amp breaker?

No, it is not safe to use a 20 amp outlet on a 15 amp breaker as it can overload the circuit and pose a fire hazard. It is important to match the outlet with the appropriate breaker amperage for safety.


Can you use 14-3 wire on a 20amp breaker?

No. A 20 amp breaker needs 12 gauge wire.


What size breaker should you use for a tnia-10 wire?

25 amp breaker


Should 25 amps breaker be replaced by 20 amps?

For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.


What best breaker rating for 1.5 hp air-con unit?

The breaker you use is determined by the size of the wire in the wall not by what is being connected to that circuit. If you have 14/2 wire then use a 15 amp breaker. If you have 12/2 wire then use a 20 amp breaker. The breaker protects the wiring not the item connected.
