The typical rating of a hot wire relay contacts is 35 amp
The amp rating for 12-volt 20-gauge wire typically ranges from 3 to 5 amps for power transmission, depending on the length of the wire and the insulation type. For longer runs, it's advisable to use a lower amp rating to prevent voltage drop and overheating. Always consider the specific application and environment when determining the appropriate amp rating. For safety, consult the National Electrical Code (NEC) or manufacturer guidelines.
A #3 copper wire with an insulation rating of 75 or 90 degrees C is rated at 100 and 110 amps consecutively.
A #4 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 85 amps.
You never, ever mix wire sizes within a circuit. However you can wire a 30 amp circuit using AWG # 8/3 wire, although that is overkill and AWG #10 wire is what you would normally use on a 30 amp circuit.
The amp rating for 10-3 wire is typically around 30 amps.
The amp rating for 6/3 wire is typically around 55 amps.
The amp rating for a 4/3 wire is typically around 100 amps.
The amp rating for a 6-3 wire is typically around 55 to 60 amps.
The amp rating for a 3 gauge wire is typically around 85-100 amps.
The amp rating for 10 wire is typically around 30 amps.
The amp rating of an 18AWG wire is typically around 16 amps.
The amp rating of 10AWG wire is typically around 30-40 amps.
The amp rating for 10-2 wire is typically around 30 amps.
The amp rating for 10/2 wire is typically around 30 amps.
The amp rating for 18 gauge wire is typically around 16 amps.
The amp rating for an 18 gauge wire is typically around 16 amps.
