The cable must have a wire gauge sufficient to the amperage of the subpanel—a 100-amp subpanel requires #4 copper wires or, more commonly, #2 aluminum wires, for example. (Aluminum is often used for feeder cables because the cost is typically much lower than that of copper wires.)

What wire size do I need to go 100 feet for a 100 amp service to a workshop?

For a 100 ampere circuit, the conductors will likely be required to be 3 AWG copper or 1 AWG aluminum.

What size wire will a 100 amp breaker accept?

For 100 AMP service, you’ll need a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire. Make sure to limit your voltage drop to 3% regardless of distance.

What wire gauge do I need for a 100 amp subpanel at the end of a 60 wire run?

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). If you want to use aluminum, you need at least #2 gauge or perhaps #1.

What gauge wire do I need to run a sub panel?

The cable you run from the main panel to the subpanel also depends on the amperage rating. You can use 10 AWG, three-conductor wire for a 30-amp panel, but for a 60-amp one, you need 6 AWG wire. If you’re installing a 100-amp panel, you need 4 AWG copper or 2 AWG aluminum three-conductor cable.

What size wire do I need for a 100 amp underground 150 ft run?

Quote from the video:
Quote from Youtube video: What size wire do i need to run 100 amp service 150. Feet what is the right wire size for 100 amp service 150 feet distance you should get two over zero awg copper wire or four over zero awg aluminum

Can you run a 100 amp sub panel off a 100 amp main panel?

Let me try and answer some of your questions. First the panels you are looking at that are rated 100A simply means you can use them for any application up to 100A.

How do you hook up a 100 amp subpanel to the main panel?

Quote from the video:
Quote from Youtube video: Cover then of course we're going to need our feeder wire coming from our main panel over to our sub panel and in this case we're going to be running three gauge copper.

What size ground wire do I need for a 100 amp subpanel?

You are correct that for a 100A feeder, the associated ground wire needs to be an 8AWG copper or 6AWG aluminum wire.

What wire size for 100 amp sub panel that’s 200 feet away?

At 120 volts, going out to 100 feet would require the wire to be a #1 awg to keep the voltage loss under 3%. At 200 feet it goes up to 4/0 awg to stay at 3% loss. If this is a 230 volt circuit, the loss is a little less, but you should certainly check the local code and verify the loss for your particular installation.

How far can subpanel be from main panel?

The right feet would be between 4.5 to 5 feet.



The cable running from your main panel to the subpanel depends on the amperage rating. For instance, for a 30A panel, use a 10 AWG, three-wire conductor. If you have a 60A panel, use a 6 AWG wire.

What size wire do I need to run a 100 amp service 200 feet?

If you consult the KCMIL list above, you can see that the 350 KCMIL wire is perfect for 200 amp service 100 feet away.

What size copper wire is rated for 100 amps?

A 100 amp sub panel wiring size requirement is #4 for copper wires and #2 for aluminum wires.

What size wire do I need for 100 amp service 300 feet?

for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit,

Can a 60 amp breaker feed a 100 amp sub panel?

You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.

What size neutral do I need for 100 amp service?

When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.

How do you wire a 100 amp breaker?

Quote from the video:
Quote from Youtube video: Off we have wired the neutral. And the ground. And we have also wired both of the 120s. To the breaker. All we have to do is flip this on to test everything out and i will take you inside.

Can you run a 100 amp sub panel off of a 200 amp main panel?

Can you add a 100 amp breaker to your main panel? Yes you have 12 slots the double pole breaker will only take 2 slots.
