Is a 12 gauge wire on 20 amp breaker safe for a sub panel?
No, a 12 gauge wire is rated for 20 amps, which matches the breaker size. It is not recommended to use a wire that matches the breaker size as it can result in overheating and potentially cause a fire hazard. Consider using a thicker wire, such as 10 gauge, for the 20 amp breaker to ensure safety for the sub panel.
Why would you use a braided hose as opposes to a traditional wire covering?
An individual would use a braided hose instead of a traditional wire covering if the wires being covered needed more protection. The braided hose is stronger than a wire covering.
Can you use a 40 amp breaker to feed a sub panel?
Yes, you can use a 40 amp breaker to feed a sub panel. The wire from the 40 amp breaker must be #8 or larger. If you intend to use the full 40 amps a larger conductor must be used. Conductors can only be loaded to 80% capacity in continuous load conditions. A #8 wire is rated at 45 amps x 80% = 36 amps. The suggested size would be a #6 rated at 65 amps x 80% = 52 amps.
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.
What size wire to run 100' from panel using a 30amp breaker for a RV?
For a 100' run from the panel to the RV using a 30amp breaker, you should use 10 gauge wire to ensure safe and efficient power delivery. This wire gauge is appropriate for the distance and the current capacity of the breaker.
Is a 12 gauge wire on 20 amp breaker safe for a sub panel?

What breaker do you use for 10 2 wire?
Use a 30 amp breaker.
Will it hurt to use a 40 amp breaker on a water heater the wire I was sold will not fit into the 30 amp on a sq. D circuit breaker?
In the United States, if the wire is #8 copper or larger (smaller number) it will work fine on a 40 amp breaker. If the wire is #10 copper, there is something wrong with the breaker if it does not fit. Pull the breaker out of the panel and look into where the wire terminates to see why the #10 wire won't fit.
Can you use 14-3 wire on a 20amp breaker?
No. A 20 amp breaker needs 12 gauge wire.
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.
Can you use 14-3 wire to power metal halide light outside?
The question isn't what you're powering with a particular gauge of wire, but what's the current draw. If the metal halide light can run on a 15 Amp breaker (from the breaker panel), fine use your metal halide in your residential application and run it on the 14 gauge wire.
What breaker can I use if I dont have a westinghouse breaker?
If you don't have a Westinghouse breaker, you should use a breaker that is compatible with your electrical panel. Consult the panel's specifications or a qualified electrician to determine the appropriate replacement breaker for your specific panel. Using an incompatible breaker can be dangerous and may violate electrical codes.
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.
