## What size wire do I need for a 75 amp service?

Wire Size and Amp Ratings

Wire Size 75°C (167°F)
AWG (mm²) Aluminum
6 (13.3) 50
4 (21.2) 65
3 (26.7) 75

What size wire should I use for a 70 amp subpanel?

2 Answers. #3 copper will provide 70 amps at 240v with a 2.74% voltage drop or #1 aluminum at 2.83% drop at 200 feet.

### What size wire do I need to run a 80 amp subpanel?

80 amp. If you’re working with 80 amp service, you need a gauge 4 copper wire, whereas it would need to be a 2 if you are going for aluminum instead. Be sure you get the right one for your subpanel and breaker!

What type of wire goes from the main panel to 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 wire size do I need to go 100 feet for a 60 amp service to a workshop?

You have to use a #4 conductor to feed a 60 amp circuit.

What size wire do I need to run a 100 amp subpanel?

#4
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.

### Will 1 0 aluminum wire fit in a 100 amp breaker?

No, Al #1/0 is good for a maximum of 125A in a dwelling service; possibly 100A if the distance is longer than 100′ or so. A 200A service requires a minimum of #4/0 aluminum or #2/0 copper; upsized accordingly if there is a long distance involved.

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

Yes, a 100 amp breaker can be placed in a 200 amp panel. The highest amperage allowed is the rating of the panel. If you want, you can use a smaller breaker and smaller amperage.

## What kind of 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.

How many amps can #6 wire carry?

Size & AMP Ratings

NM, TW, & UF WIRE (Copper Conductor) SE CABLE (Copper Conductor)
12 AWG – 20 AMPS 6 AWG – 65 AMPS
10 AWG – 30 AMPS 4 AWG – 85 AMPS
8 AWG – 40 AMPS 2 AWG – 115 AMPS
6 AWG – 55 AMPS 1 AWG – 130 AMPS

### What size wire do I need for 60 amp subpanel?

2 Answers. 6AWG copper wire would be the minimum for a 60A subpanel but with a 105ft distance you have too much voltage drop and need to go up to 4AWG copper to keep the voltage drop within acceptable limits (usually 5%).
