Can a main breaker panel be used as a sub panel?
There’s no problem with having a main breaker in a subpanel. It’s required if your panel is in a separate building and has more than six breakers, but there’s nothing prohibiting it in any other case.
Can I run a 200 amp sub panel off 100 amp main?
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,
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.

What size wire do you use for a 200 amp sub panel?
The 250 KCMIL wire is the perfect size wire for 200 amp service because it has 255A ampacity (a minimum of 250A ampacity requirement is satisfied).
Can you daisy chain sub panels?
Answer: Yes. The main electrical service panel is where branch circuits originate. A branch circuit consists of the circuit conductors between the final over-current device protecting the circuit and the lights, receptacles and equipment supplied by the branch circuit.
How many amps can a sub panel be?

Can a sub panel be the same size as the main panel?
Moderator. Yes, the 42 circuit limit lighting and appliance branch circuit panel has been removed in the 2008 NEC and there is no size restriction for a subpanel.
Can a sub panel have more amps than a main panel?
You are fine. The 200 amp breaker in the main panel will protect the wires leading to the sub. The main breaker in the sub is not strictly necessary, except as a local shutoff. You could as easily use a sub designed with no main, feeding directly to the bus bars.
