Bear with me here. I searched this topic and came up with conflicting results, opinions, code year, etc.

I do apartments. Can I provide a single 20A circuit to a receptacle in the cabinet above the range to power a microwave and/or a range hood? Both would be plug in. Nothing else is on the circuit but the microwave and the hood.

Thanks
 
Yes, this is fine. Actually under the 2005 NEC an individual branch circuit is required.
 
How do you wind up with a hood and a microwave over a range?

If you're saying can a dedicated circuit supply "either/or", while cord and plug connected, the answer is yes.

If it's a hood, it has to be on an individual circuit if it's cord-and-plug-connected, in case someone installs a microwave someday. See 422.16(B)(4), list item (5). :)

If it's just a microwave, the ordinary rules of 210.23 apply. Go figure. :D
 
Help!

Now I need to have BOTH a microwave and a small separate range hood. (Latest input from client.)

The microwave and the range hood will be installed and provided in each apartment.


Can I have both on the same 20A circuit? This would save us much grief. I have at least five apartment complex projects (hundreds of units total) that need this "change." I have a 20A "microwave" circuit above the range that's independent of the two 20A small appliance circuits.

And I just revised all these drawings last week to "value engineer" them. Yes, I left the above three 20A circuits. I REALLY don't want to have to go back and revise them AGAIN!
 
If you check the manufacture instructions, It will state "Seperate Circuit". Put the hood on a near by lighting ckt.

LMAO :D
 
no comment. Now, about my problem? BTW, I have no way to get a copy of so called instruction sheets. Who knows which vendor the field will actually use anyway! Load wise, a microwave is NOT a continuous load, the hood likely. Thus: Hood ~2.5A x 1.25 = 3.125A . The MW is ~ 14A. Thus the MCA = 17.125 which is less than 20A So, load wise I have lots of room.

You have my permission to combine both loads on one 20amp branch circuit. If anyone questions this just tell them I said it was OK.

Ask and ye shall recieve:
17-21 Log #219 NEC-P17 (422-16(B)(4) (New) )
Final Action: Accept in Principle in Part
Submitter: Don A. Hursey, Durham County Inspections Department
Recommendation:
Add new text to read as follows:
Permanently installed range hoods shall be permitted to be permanently connected or cord and plug connected.
Substantiation:
Many times range hoods are removed and replaced with a "microwave type" range hood. Allowing cord and plug connection will make the installation much easier for the homeowner because no "electrical change" to the wiring system will be required.
Panel Meeting Action: Accept in Principle in Part
Add a new section to read as follows:
422.16(B)(6) Range Hoods. Range hoods shall be permitted to be cord-and-plug connected with a flexible cord identified as suitable for the use on range hoods in the installation instructions of the appliance manufacturer, where all of the following conditions are met.
(1) The flexible cord shall be terminated with a grounding type attachment plug.
Exception: A listed range hood distinctly marked to identify it as protected by a system of double insulation, or its equivalent, shall not be required to be terminated with a grounding-type attachment plug.
(2) The length of the cord shall not be less than 450 mm (18 in.) and not over 900 mm (36 in.).
(3) Receptacles shall be located to avoid physical damage to the flexible cord.
(4) The receptacle shall be accessible.
(5) The receptacle shall be supplied by an individual branch circuit.
Panel Statement:
The permission to use cord-and-plug connection provides the ability to upgrade to a combined microwave range hood. The panel added the additional requirements to ensure a safe installation of a combined microwave range hood.
Number Eligible to Vote: 12
Affirmative: 12
 
Ragin, better specify direct-wiring (as opposed to cord and plug connecting) the range hood, or else it will need to be on a dedicated circuit. 422.16(B)(4)(5).

This is one of those things in the code that makes no sense. If the manufacturers specs or the load doesn't require dedicated, why should it matter if the hood is hardwired or plugin ?

Separate micro & hood is not common but a hood above a gas range is common.

If I hardwire the hood, I can put it on the same circuit as the 120v plug for the gas range. But if I put the hood on a cord, I can't run the gas range clock off the same circuit.

I used to hard wire range hoods but that became an issue on finals when there was no hood on site,that held up the final inspection.Also if hardwired the breaker would have to have a lock out since there would be no means of disconnect.A simple wiremold box was the best thing to use.If a micro or range hood would be installed ,the HO could install them and not hold up our finals.Same for disposal or d/w.Cord connection is the way to go.For a micro just make sure the stub out is at the side of the cabinet if it is a vented system since the cabinet guys will box in the vent within the cabinet.
