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

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

What size wire do I need to run for 100 amp sub panel?





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 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

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

Like I said before, for 100 AMP service, you’ll need a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire. If you’re looking to install 200 AMP service, you’ll need a #2/0 AWG copper wire or a #4/0 AWG aluminum or copper-clad wire.

What size wire do I need for a 100 amp underground 300 ft run?

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,

How deep should a 100 amp service be buried?





In general, bury metal conduits at least 6 inches below the soil surface. You may also run them at a depth of 4 inches under a 4-inch concrete slab.

Will #2 wire fit in a 100 amp breaker?

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

What size copper wire is good for 125 amps?

125A is #1 copper or #1/0 aluminum (you need to call it 120A feeder, but you get to round up to 125A breaker since 120A is not made.) If you need full declared 125A you’d need 2/0 aluminum.

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

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.

What size wire do I need to run 150 feet?



150 Foot Run – A 120-volt circuit on a 20 amp breaker will require 6/2 AWG wire for 150 feet.

What size wire do I need for underground?

Sizing the wires, or conductors, for an underground cable is no different than sizing for other household circuits and is typically based on the total load, or electrical demand, of the devices on the circuit.



For 120-volt circuits:

14 AWG 50 feet
12 AWG 60 feet
10 AWG 64 feet
8 AWG 76 feet
6 AWG 94 feet


How far can you run #2 aluminum wire?



400 ft.

Example calcuation 2 – Aluminum Wire, 1 phase power



Cable run: 400 ft. 1 conductor per phase utilizing a 1000 kcmil Aluminum conductor installed Direct Buried will limit the voltage drop to 2.61% or less when supplying 194 amps for 400.0 feet on a 240 volt 1 phase system.

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. You can for example add a 60A breaker to your existing panel and protect the new subpanel with a 100A rating.

What size wire do I need for a 200 amp underground 300 ft run?

The NEC is the electric code used in the United States. The minimum size for a grounding wire for 200 amp is #4 AWG copper or #2 AWG aluminum, according to Article 250 of the 2020 NEC.

What size wire do I need to run 200 amp Service 200 feet?



That, however, will likely end with you frying the wire. This is known as NEC 80% requirement for wire sizing. In the case of 200 amps breakers, this means you will need a wire with at least 250A ampacity to connect a 200 amp service.

How far can you run 4 AWG wire?

This means that a wire for a 60 amp sub-panel 150 feet away must handle at least 97.5 amps. 6 AWG wire can handle 65 amps, 4 AWG wire can handle 85 amps. In this case, due to 150 feet distance, both of these wires have a too low amperage.

What size wire do I need for 200 amp service?

The Short Answer: Like with aluminum, you’ll need a #4/0 copper-clad aluminum wire for a 200 amp service.

How many conductors can you have on a 200 amp service?

RESIDENTIAL UNDERGROUND SERVICE INSTALLATION 100-200 AMP, 120/240 VOLT, 3 WIRE, SINGLE PHASE. 1 3 CONDUCTOR SERVICE TO HOUSE. SEE NOTE E. 2 NON METALLIC CONDUIT IF REQUIRED.

What is the difference between 2 0 and 2 AWG?



2/0 AWG will handle around 190 amps, whereas 2 AWG will handle around 94 amps.
