I am about to have kitchen remodeled and new appliances installed. The range/ microwave is currently electric with a single 220 circuit feeding it. We will be replacing with a gas range/electrical micro hood. Can i easily split the 220v into two (or one) 110v circuits to power the range electrical needs plus the microwave?

Most likely not advisable. A qualified electrician may be able to do it and maintain the Code. But it would be technical. Advise that you run a singe 12/2 romex from the panel on a 20 amp circuit to the receptacle for the igniters of the gas range then to the microwave hood connection for that peice of equipment.
A lot of ranges were wired before 1998 with an SEU cable that had a red,black,bare wire in it only. This was approved by the NEC at that time. You wouldn't have the insulated white or grey neutral needed to carry the unbalanced load of a multiwire circuit.
If you do try it remember to downsize the overcurrent device to 20 amp with a double pole breaker to disconnect all hots of that multiwire circuit.

Advise not to try it, but if you do be sure that it is inspected by the authority having jurisdiction and this type wiring is highly advised to be performed by a highly qualified electrician only and still inspected.

Good Luck

You can make this two circuits. Replace the existing breakers with 20A breakers. Ensure they are on opposite legs of the incoming service. (they already should be). Tie the new breakers so power can be turned off to both circuits at once. Replace your 220 outlet with a junction box. Run 12/2 w/gnd cable from the junction box to your new outlets. Use black from one breaker for the first circuit, Use red from the other breaker for the second circuit. Neutral will be shared. When sharing neutral, always pigtail the neutral wire at each outlet (or at least the first outlet on each circuit) so the neutral is not broken in case an outlet is removed for servicing. DO NOT continue the circuit by using the side terminal screws on the outlet. If you use the terminal screws and an outlet is removed, you could place all the receptacles connected to one leg in series with those connected to the other leg, at 240 volts.
Somebody jump in if I forgot something.

OOps, Just read wg's reply, listen to him. This guy knows more about electric than should be allowed. What I'm saying is correct if in the 220 outlet you have a black, red, white and ground. The black and red should run to breakers, the white and ground should run to respective buss bars.

The advice that has been given is not very promising for good, safe, and code passing results.
Start fresh with a new 12/2 and if you would like, remove the 2-pole breaker and replace with (2) single pole breakers, one of them 20A to supply the new circuit. Remove the old range receptacle and install a blank coverplate if disconnecting the cable from the panel. Remove the old cable from the panel to prevent questions in the future.

I hesitate to reuse the existing cable if an expert is not present-besides the old cable is probably too large to work with anyway.

Respond with any other questions to understand what we have said in reguards to this situation.
