A # 12 copper wire insulation 90 degrees C is rated at 20 amps.
<><><>
But be very careful: before you can get proper advice about the right size wire to use you have to include information about the length of run and the intended installation method!
Is it to be hung between buildings in the open air or fixed to a wall, etc. ... ?
Is it to be in a conduit or clipped to a cable tray, or is it running underground, etc. ... ?
<><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What size circuit breaker for GFCI circuit in a normal size bath?
Normally it is a 20 amp using AWG 12/2 gauge wire. But it really depends on what size wire is on that circuit. If it is white AWG 14 gauge then use a 15 amp breaker. If it is yellow AWG 12 gauge then use a 20 amp breaker.
What size wire for 100 feet 20 amp circuit to run pond fountain?
12 gauge underground wire or if you think you will ever add any devices to this circuit use 10 gauge.
What wire size is needed for 15 volt circuit?
The wire size depends on how much current it will conduct.
What is the maximum breaker size for these gauges wire?
You listed no gauge wire. This is the required breakers.14 gauge - 15 amp12 gauge - 20 amp10 gauge - 30 amp8 gauge - 40 amp
How big is 6 gauge wire?
The size of the wire is stated by its gauge under American Wire Gauge. Six gauge wire is size 6 AWG.
14 gauge wire can be on what size circuit breaker?
A 14 gauge wire is typically used on a 15 amp circuit breaker. It is not recommended to use a larger circuit breaker with a smaller wire size as this can create a fire hazard.
What size wire in a 40 amp 12 volt circuit?
Use 8 gauge wire.
What size wire for an 80 amp 220 volt circuit?
# 3 gauge
What size circuit breaker for GFCI circuit in a normal size bath?
Normally it is a 20 amp using AWG 12/2 gauge wire. But it really depends on what size wire is on that circuit. If it is white AWG 14 gauge then use a 15 amp breaker. If it is yellow AWG 12 gauge then use a 20 amp breaker.
Explain the rules for GFCIs in bathroom wire size wiring?
In bathrooms, GFCI protection is required for all receptacles to prevent the risk of electric shock near water sources. The wire size for GFCI-protected circuits is typically required to be 12-gauge copper wire to handle the higher current demands in bathrooms. This ensures safety and compliance with electrical codes.
What size wire for 100 feet 20 amp circuit to run pond fountain?
12 gauge underground wire or if you think you will ever add any devices to this circuit use 10 gauge.
What size ground wire is needed for 20 amp?
For a 20 amp circuit, a 12-gauge copper ground wire is typically recommended. This wire size can safely handle the current and provide proper grounding for the circuit.
What wire size is needed for 15 volt circuit?
The wire size depends on how much current it will conduct.
What is the use of wire gauge?
Wire gauge is used to determine the size wire needed to carry the correct amount of current for the job. It must be sized appropriately for the current in the circuit you are building.
What is the maximum breaker size for these gauges wire?
You listed no gauge wire. This is the required breakers.14 gauge - 15 amp12 gauge - 20 amp10 gauge - 30 amp8 gauge - 40 amp
Ground wire size for 200?
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.
How big is 6 gauge wire?
The size of the wire is stated by its gauge under American Wire Gauge. Six gauge wire is size 6 AWG.
