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 size wire do I need for 100 amp service?
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.)Feb 4, 2022.
What wire size do I need to go 100 feet for a 100 amp service to a workshop?
A 100 Amp branch circuit would require #3 AWG Cu or #1 AWG Al wire.
Can you use 6 gauge wire for 100 amp service?
You can feed as many 100A subpanels as you want with #6 wire, as long as the wire is supplied from 60A breakers. Breakers protect wires.
What size wire do I need for 100 amp service 300 ft away?
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, Jul 28, 2014.

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 2/0 AWG Copper wire or 4/0 AWG Aluminum wire for single-phase circuits. And, 1/0 AWG Copper wire or 3/0 AWG Aluminum wire if you have three-phase circuits. For these wires, the average voltage drop should be 3%.

What is #2 copper wire?
#2 Insulated Wire #2 grade insulated copper consists of unalloyed wire – thinner than 16 gauge – which includes heavy, double or plastic insulation. The grade generally covers many common types of telecommunications wiring as well as electronics such as outlet and extension cords.
What size wire do I need for a 100 amp underground 200 ft run?
To feed a 100 ampere secondary panel 200 ft. from the main panel, you’ll want to use 1 AWG copper or 2/0 aluminum conductors. This is large enough to safely carry 100 amperes, and to maintain power quality over the distance.
What size wire do I need to run 60 amps 100 feet?
What size wire should I use for a 60 amp subpanel? You can get away with 6 AWG when you have a short run of wire, however, due to voltage drop, if you ever decide you want to go more than 100 feet then a 4 AWG is the size you should choose.
Can I run a 100 amp sub panel off 200 amp main?
Of course you can, you can add the 100 amp breaker to your 200 amp as long as it isn’t overloaded, to start adding the subpanel you must first calculate how many yards it will be from the main panel to the subpanel, there is a formula that calculates how much friction will be on the wire at the connecting distance, Mar 14, 2018.
How many amps can 6 3 wire carry?
6/3 wire is a bare copper wire which carries current and carries a current of 55 Amps approximately.
Will a 100 amp breaker fit a 1/0 wire?
Yes, 1/0 aluminum wire is rated for 100 amps & fits just fine into the terminals of 100-amp breakers rated for aluminum conductors.

What’s the difference between bare bright copper and number 1 copper?
Bare bright copper wire is defined as clean, bare, uncoated, unalloyed copper wire, not smaller than No. 16 gauge wire. Bare bright also should be free of copper tubing, burnt copper wire and nonmetallics. 1 copper consists of clean, untinned, uncoated, unalloyed copper wire and cable, not smaller than No.
Is it worth stripping copper wire?
If you chose to strip it, you will end up with 90 pounds of copper don’t forget 10 pounds in plastic waste and in today’s market you will get $1.90 per pound for stripped copper wire so your 90 pounds will net you $171.00 difference of $21.00 between stripping it or selling the way it is, just want to mention one thing.
