What size wire do I need for a 70 amp sub panel?
There is a mininum wire size which is required based on the circuit breaker rating.
That size is #4 copper or #2 aluminum.
You get this number by using a quality voltage drop calculator by specifying the breaker amperage and a wire length of 1 foot..
What size wire do I need for a 60 amp subpanel?
That would be 4-gauge wire. In practice, however, it’s common to wire 60-amp breakers with 6-gauge, 3-conductor wire because an appliance that needs a 60-amp breaker seldom draws the full 60 amps. If you’re installing a 60-amp subpanel, however, it’s best to connect it to the main panel with 4-gauge wire.
What size wire is needed 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?
If this were my shop, and I needed 60a service at 100 feet, I would likely run 8 gauge wire, 8–3w/ground. this gives you the opportunity to run two 120v circuits off two different breakers from your main panel to the shop.
What size wire is good for 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.
What size breaker do I need for a 100 amp sub panel?
You can use the 100 amp panel off a 60 amp breaker if you determine that it is adequate, but I would suggest that in sizing your feeder wires and conduit it would be a good idea to size them to accomodate 100 amps. Your feeder wires are where most of the work for this project will be.
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″.
Can you run a 100 amp sub panel off a 100 amp main panel?
You can run a 100 amp subpanel off a 100 amp main panel because the total can be up to twice the amperage of the box, meaning you could run a subpanel of up to 200 amps. What’s critical, though, is that the subpanel is safely and correctly connected to the main panel and that you don’t overload the service panel.
Can 8 gauge wire handle 50 amps?
8 AWG may carry a maximum of 70 Amps in free air, or 50 Amps as part of a 3 conductor cable.
What size aluminum wire do I need for 100 amp sub panel?
Use 1 AWG copper or 1/0 AWG aluminium for the current carrying conductors.
Can 8 gauge wire handle 60 amps?
“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”

Can you feed a 100 amp sub panel with a 60 amp breaker?
Nope. The breaker protects the wire leading to that subpanel. The “100 amp” rating of the subpanel is the max rating that you can feed it at.
Does a sub panel need its own ground rod?
It’s not used unless a ground fault occurs, in which case it’s only purpose is to provide a path back to the source so that a protective device will trip. (breaker, fuse, etc.) … So for your first question: no, it is not against code to install a ground rod at the subpanel. It is actually required by code.
Can you use a 100 amp breaker for a 125 amp sub panel?
A 125 amp rated panel with a 100 amp OCPD as the main and a sub with a 20 or more breakers.
Can I put a 50 amp breaker in a 100 amp panel?
You can use any size panel you like as long as its fused for the service entrance conductors. Meaning you could install a 200 amp MLO or breaker panel inside with a 100 amp disconnect feeding it.

What size wire do I need for a 50 amp subpanel?
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.
