4-gauge wire
This is typically a three-wire cable with three insulated conductors plus a bare copper ground wire. The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires, for example.
Thereof, What wire do I use for a 50 amp sub panel?
For example, 6-3G cable is designed for 50 amps when the length of wire does not exceed 55 feet. Beyond that length, a thicker wire is required, due to the voltage drop.

Subsequently, question is, What size wire is needed for a 125 amp sub panel?
Also, What size breaker do I need for a 125 amp sub panel?
If you have a 125 amp breaker you need 125 amp wire. See the table here. You need to use the 75° column since no one makes a 90° breaker just yet. Since this is a single phase dwelling service you can use #2 AWG copper or 1/0 aluminum for a 125 amp service or main feeder.
What size wire do I need for an 80 amp sub panel?
Schedule 80 PVC conduit would need to be 1-1/4″ for 3 wire or 1-1/2 for 4 wire. In your sub Panel the ground and neutral needs to be isolated many times they are tied together at the factory with a large copper wire connecting the 2 grounded / grounding buss bars. Other than that you should bury this a minimum of 18″.
What is 6’3 Romex rated?
The 6/3 Romex is hooked up to a 60amp breaker. Somebody told me that 6/3 Romex is only rated up to 55 amps BEFORE derating factors. So they told me it’s a fire hazard to have wire that is rated for less amperage hooked to a higher amperage circuit breaker.
Can 6 gauge wire handle 50 amps?
For a maximum of 50 amps, you’ll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances.
Can you wire a subpanel with 3 wires?
A ground rod and the earth are too high in resistance to trip the breaker in the event of a fault so the neutral and safety grounds have to bond together in a three wire subpanel so that there is a path sufficiently low in resistance to trip the breaker in the event of a fault.
What size wire is needed for a subpanel?
The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires, for example.
What wire do you use for a sub panel?
This is typically a three-wire cable with three insulated conductors plus a bare copper ground wire. The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires, for example.
What wire size do I need to go 100 feet for a 60 amp service to a workshop?
My rule of thumb for a service connection is to use the largest conductors that will fit. If 6 AWG fits, then use it, but 8 AWG would work. I know, it’s only a 100 foot run, but your workshop may eventually grow to have more power loads, so a larger service conductor provides a better power factor (cooler wires).

What wire do I use for a 100 amp sub panel?
You need a 3-3-3-5 copper SER cable to carry 100 amps (that’s three #3 gauge for the two hot wires and the neutral and a #5 gauge for the ground).
What size wire is required for 100 amps?
#4
