What do I need for a 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 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.
What size wire do I need for a 100 amp sub panel 100 feet away?
If you check the wire size chart (you have the link in the introduction), the #0 AWG wire (also known as 1/0 AWG wire) has 150 ampacity. That means that #0 AWG wire is the perfect size wire for 100 amp service 100 feet away.
What do you need for a 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. Which wire used is determined by the voltage drop and length of the wiring. Many licensed electricians use #2 copper-clad or aluminum wire size.
What size aluminum wire do I need for 100 amp service?
#4 AWG #2 AWG
| SERVICE ENTRANCE CONDUCTORS SIZE AND RATING | ||
|---|---|---|
| Service or Feeder Rating | Copper Conductors | Aluminum or Copper-Clad Aluminum |
| 100 Amps | #4 AWG | #2 AWG |
| 125 Amps | #2 AWG | #1/0 AWG |
| 150 Amps | #1 AWG | #2/0 AWG |
Does a subpanel need a ground rod?
Yes, any sub panel outside of the main building requires it’s own ground rod and a ground wire back to the main building.
Does a subpanel need to have a main breaker?
A main breaker on a sub-panel is not necessary because this is in the same building (if you are in a different building then NEC 225.31, 225.32, 225.33 apply). That said, having a main breaker in the sub-panel is also acceptable.
How much load can a 100 amp panel handle?
In other words, a 100-amp electrical service should be expected to provide no more than 19,200 watts of power load at any given time.
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.
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.
How far can you run a 100 amp sub panel?
There is no maximum distance and no NEC requirement to provide voltage drop compensation. A quick look at the Southwire VD calculator came up with #1/0 Al with 100 amp load at 150′.
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 do you wire a 100 amp sub panel?
Quote from the video:
Quote from Youtube video: Type of wire if you're using six gauge or smaller wire. You can actually get multiple colors and you will have to get the correct colors.
What wire do I need for 100 amps?
For 100 AMP service, you’ll need a #4 AWG copper wire or #2 AWG aluminum or copper-clad wire.
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.
