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.

Can I put a 100 amp subpanel to a 200 amp main panel?

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,

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 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.

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.

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.
