Micro/rangehood circuit - Electrician Talk - Professional Electrical Contractors Forum

jewalker88 · 04-20-2011, 07:32 PM

My local AHJ stated that 110v outlet for gas range can't come off of the micro/range hood cir. I can't find a code to suport that. anyone have any Ideals?

Why not ask the AHJ?

It could be article 422.16(B)(4)exception(5)

That is my prefered method. I put a 50 amp range receptacle in and a 110 volt duplex that I then feed to the micro/fan. You didn't feed the gas range from the SABC, did you? You can, but can't then feed the micro/fan from it. 210.52(B)(2)exc 2

Damm, I will have to change my ways

. I guess the gas range outlet is coming off the SABC from now on.

I did the same thing for years. I have never been caught on it but it could be a reason for a red tag. I thought about writing an exception to that section for a gas range receptacle.

I already run 2-20 amp SABC to the kitchen, 1-20 amp to the dinning room and 1-20 amp for the range/mico/fan. It would seem better to run the three together instead of taking the range off the SABC. JMO

no had dedicated circuit for the micro/fan and gas cooktop

That would be a good exception, that makes a lot of sense.

I used to do it too without realizing there was a problem, until
a coworker "caught" me doing it. Looked it up, and sure enough.

Thing is that the micro is over 50% of the branch circuit rating for cord connected appliance so can't share that circuit with lighting and receptacles. If I remember right..

That is correct but the exception would have to allow it.
Some have argued that a microwave range hood is listed as a microwave so technically it would not fall under this article. However, I know the inspector who wrote this rule and his reasoning was microwave range hoods.

Actually most are listed as both a microwave and a rangehood because they must meet both listings if the microwave also serves as a rangehood.

I thought Bob actually dug up some info a year or so ago stating that they were listed as microwaves. I never bought into it but thought it worth mentioning.

The one that I looked at had a listing as both a microwave and a rangehood.

Which exception?

Post #6, Dennis was talking about writing one.

I think 210.23(B)(2) is fairly clear. It makes sense to me that you don't want to have over 50% of a circuit that is shared being utilized by one appliance.

The issue is how much the range would add to that circuit. If the micro was on the counter, we could wire the gas range receptacle, fridge receptacle, plug the micro in and what ever else on the same SABC. This exception would make more sense.
