Can I put a 100-amp subpanel on a 100-amp 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.

How big of a sub panel can I install off a 100-amp service?





However, NEC prohibits more than 42 circuits, so you can only choose between 20-42 breakers for a 100-amp panel. Breakers or circuit breakers act as a switch for cutting off power from the main electrical supply.

Can an electrical sub panel feed another sub panel?

Answer: Yes. The main electrical service panel is where branch circuits originate.

Can you have 2 100-amp panels?

If you swapped out your meter pan for a meter-main with a 100A breaker, then yes, your plan would work. You could come off the 100A breaker and split to both the house and the workshop. However the wire to the workshop would need to be 100A rated (so the 100A meter-main breaker protects it).

How do I install a subpanel to a full main panel?

How far can subpanel be from main panel?

The right feet would be between 4.5 to 5 feet.



The cable running from your main panel to the subpanel depends on the amperage rating. For instance, for a 30A panel, use a 10 AWG, three-wire conductor.

How many electrical sub panels are allowed?



Even though there is no limit on the number of subpanels that you can add to a circuit, it shouldn’t exceed 160 amps when you’re using a 200 amp main panel. Always follow this guide to install subpanels effectively.

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.

Does a subpanel need a main breaker?

Subpanel 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 do you wire a subpanel in a shed?

Where should feeder wires to a subpanel be connected?

In the subpanel, route the feeder wires, cut and strip them, and connect to terminals. Connect the black and red wires to the hot bus bars, the neutral wire to the main neutral terminal, and the ground wire to the ground bus bar.

How do you hook up a 100 amp sub panel to a garage?

Quote from Youtube video: From so and here's where the 100 amp breaker goes and then we'll drop wire down run it all the way across in through there.

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

Is feeding a 200A sub from a 200A main legit? Yes, and you don’t even need another 200A breaker. The 200A breaker alread present in the panel will suffice, and so you can use a subfeed lug kit as DrSparks advises.

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.

How do you feed a subpanel from the main panel?

Quote from the video:

Can you feed a 100 amp sub panel with a 60 amp breaker?

You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.

What size breaker do I need for a subpanel?

Based on your question, since you will be having a subpanel, you want the breaker feeding the subpanel to be sized for the subpanel or slightly smaller. So if you purchase and install a 200A subpanel, then the breaker should be 200A. If you use a 125A subpanel, then use a 125A breaker.

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 you feed a 125 amp subpanel with a 100 amp breaker?

If it’s a 125 amp panel, then you can use a 100A breaker on the main panel to feed the breaker. The new sub panel must always have the same ampacity rating as the panel that is feeding it.

What size aluminum wire do I need for 100 amp service?

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.
