## 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].”

## What size breaker do I need for 8 gauge 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.

## How many amps can #6 wire carry?

## 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.
