We always put the microwave on a dedicated 20A circuit, does it state in the NEC that this is required, I'm looking through article 210 but don't see any specific requirement. Thanks
(2) Utilization Equipment Fastened in Place. The total
rating of utilization equipment fastened in place, other than
luminaires, shall not exceed 50 percent of the branchcircuit
ampere rating where lighting units, cord-and-plugconnected
utilization equipment not fastened in place, or
both, are also supplied.
Is it a microwave or a microwave/range hood that is cord connected?
It is not required by the nec but the installation instruction or the wattage of the unit will demand it.
Look at article 210.23(A)(2)
This was a question on my RW exam, read something like... a microwave in a dwelling shall be
a. dedicated 20A
b.dedicated 15A
c. supplied by one of small appliance circuits
d. on with kitchen counter circuit
I chose a. since thats what I've always done since I started in the trade with every company I've worked for but this is kind of a trick question. c. and d. are the same thing (small appliance circuit)
As written it is poor question. The word "shall" throws any correct answer off because no more info is provided.
None of the answers satisfy the absolute word "shall" in the question.
Why?My understanding is an over the range could go on the kitchen light circuit.
(4) Range Hoods. Range hoods shall be permitted to be
cord-and-plug-connected with a flexible cord identified as
suitable for use on range hoods in the installation instructions
of the appliance manufacturer, where all of the following
conditions are met:
(1) The flexible cord is 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 is not less than 450 mm (18 in.)
and not over 900 mm (36 in.).
(3) Receptacles are located to avoid physical damage to the
flexible cord.
(4) The receptacle is accessible.
(5) The receptacle is supplied by an individual branch
circuit.
My understanding is an over the range could go on the kitchen light circuit.
Why?
If you consider the micro/range hood over the range was a hood instead of a microwave then art. 422.16(B)(4) comes into play
If it is a microwave then the article mentioned above would come into play 210.23(A)(2)
True, but a hood is different then a micro.
The wording could be better but I think the intent of the code was for MW/hood combos or the possibility of replacing with one.
