New home wired with double pole breakers to two sperate circiuts. Two hots red and black one common for both circuits. So if I were to have trouble with my mircowave it would also trip the refrig. Is this legal in Fl.

I don't have an electrican it was put in by builder. Where I came from in NH I was told this was incorrect. Only double poles are used for 220 not two 110 ckts.

Are you sure they are double pole or are they slim breakers with individual breaker trips?

It's legal everywhere. It's called a multi-wire branch circuit.
Two-pole, or tied, breakers were always legal, recently they became code required.

Actually, it is the neutral that is the common wire in a multiwire circuit. It is shared by both the hots coming off the breakers.

This type of circuit is most often found in the kitchen, Code requires a minium of two 20 amp circuits to serve the counters,

You must never disconnect the neutral from either part of the circuit and NEVER work on either part of the circuit while power is on. Shut the breaker off before doing any work.
