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 to use for 100 amp service?

Size Wire for 100 Amp Service

Wiring a 100 amp breaker panel requires either **#4 copper wiring or #2 aluminum or copper-clad wiring**.

## What type of wire goes from meter to panel?

Electrical wire

For this project, you will need **#4 AWG copper wire**. Based on the current and voltage rating of the meter and breaker, #4 size AWG copper wire is the highly suggested type and size of wire.

## What size wire do I need to run 100 Amp Service 100 feet?

A 100A breaker would require a **#8 cu or a #6 al**. If you are calculating full load then the grounding conductor must take voltage drop into account and rise a full two sizes more just like the current carrying conductors or a #4 cu or #2 al.

## Will #2 wire fit in a 100 amp breaker?

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.

## 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 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*

## How do you wire a main panel to a meter box?

Quote from the video:

Quote from Youtube video: *So technically what you have is two 120s sharing a common neutral. And then that can either be combined for our 240 out here or any 120 volt outlets that we want to run.*

## Is copper or aluminum better for service entrance?

Choosing a Service Entrance Cable

Aluminum service entrance cables are cheaper, lighter, and generally easier to install, whereas **copper cables are more durable with superior electric conductivity**.

## How do you wire a breaker box to a meter?

Quote from the video:

Quote from Youtube video: *So right down here is the hole we drilled through from the outside of that j block. And we have the meter base setting right here. And this is that scu cable coming in and what we're going to do with*

## What size breaker do I need for a 100 amp sub panel?

20/24 panels can hold 16 full-sized and 4 twin breakers (24 circuits in total). The number of breakers can max out to 30-42, too, depending on the design of your 100-amp pane. However, NEC prohibits more than 42 circuits, so you can only choose between **20-42 breakers** for a 100-amp panel.

## 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.

## How do I calculate what size wire I need?

**How do I calculate wire size for motors?**

- Multiply the resistivity (Ω•m) of the conductor material by the peak motor current (A), the number 1.25, and the total length of the cable (m).
- Divide the result by the voltage drop from the power source to the motor.
- Multiply by 1,000,000 to get the result in mm
^{2}.

## What wire size do I need to go 100 feet for a 60 amp service to a workshop?

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.

## How far can you run a 30 amp 10 gauge wire?

How far can 10 gauge wire carry 30 amps? 30 amps carried over a 10 gauge wire is not meant to be run over far distances. If you plan on going over **150 feet**, you should upgrade the wire size from 10 gauge to 8 gauge.

## 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.

## How far can you run 100 amp service?

Most ampacity charts are **up to 100 feet** and go up one size of additional 100 feet. So, if using a 100amp breaker at the service side, then need to minimally size the wire accordingly and there are different rating for non burial, burial and in conduit Aluminum sizes will be larger than copper.

## What kind of wire do I need to run from garage to house?

In general, you need **10-gauge wire for a 30-amp subpanel, 8-gauge for a 40-amp one and 6-gauge for a 50-amp subpanel**. If you need a 100-amp subpanel, you’ll be running beefy 3- or 4-gauge cable with a 6-gauge ground wire.
