Adding 240v Microwave to Oven Circuit?
Can someone tell me how to wire a new 240v microwave in to existing 240v Oven circuit? I THINK it is wired in parallel. I want to be sure how I do it is safe and code. Do I ad an additional Junction box? Can you tell me what wires connect and where? Hope that makes sense? Basically need a simple wire diagram indicating connections.
Thanks so much!

How many amps is the oven circuit? How many amps does the microwave need?
Most likely you need a new circuit just for the microwave.

Where are you located? In North America microwaves are 120 volt, 60hz. If you have a 240 volt one then it probably needs 50hz and won't work in N. America.

There is no code compliant way to connect a microwave in parallel to an oven circuit.

@ Pilot Dane,
It is probably one with a built in convection oven (A microwave & regular oven combined). I wonder if a small sub panel would be code compliant (although you run the risk of tripping the main oven's breaker if you use both at the same time)

If a non-portable appliance would use more than half the amperes rating of the circuit it is connected to then it should have its own circuit.
Every appliance, tool, or other device has a maximum circuit rating which rating is not always easy to find out. Most likely the microwave oven has a maximum circuit rating smaller than the rating of a circuit that would be needed to operate both it and the main oven at the same time.
Partly because general purpose branch circuits may be 20 amps, all lights, small appliances, electronic gear, etc.for use on such circuits have maximum circuit amperage of at least 20 to meet safety standards such as Underwriter Labs'.
