I just bought a new over the range microwave. The old range hood is
hard wired, the new microwave is plug in. I was just wondering on
what my options are. I need to know what to do with the hard wire
that i will disconnect from the range hood.
Put a receptacle on it, of course.
Visit the electrical department at your nearest hardware store or home center,
and buy an "old work" box. Cut an appropriately sized and shaped hole in the
wall for the box, pull the cable out through that hole and insert it in the
box, mount the box in the wall, and mount a receptacle in the box.

The existing hood is probably on a lighting circuit, with other lights. The
new microwave will require a dedicated circuit. Typically you will install
an outlet, either flush or surface, in the cabinet above the microwave. The
microwave will have the cord and plug coming off the top right side of the
unit. You cut a hole through the bottom of the cabinet and pull the cord
into the cabinet and plug it in
I bought a female plug to go on the end of the wire and plugged the
microwave into it and let it hang in the wall. I did not want a box in the
cabinet above the microwave as that just seems dumb. The way I did it you
see no wiring at all just like with the range hood and I did not cut the
cord to the microwave.
No I am talking about putting an end like the end of an extension cord (a
good heavy duty one) on the wire that went to the range hood and plugging
the new microwave into it. What is wrong with that?
It's still considered a splice or joint and can't be done without a box and
cords can't be run through partitions, also the NEC states that equipment
must be installed as per instructions. If the cord was intended to go out
the back into the wall, it would not be coming off the top of the microwave.
Essentially what you did looks fine, appears to work fine, but is considered
illegal and dangerous by the folks that write the electric code, who have
some experience with this type of Rube Goldberg wiring
Option1) Drill a hole in the cabinet above the microwave and let the cord
come threw the bottom of it in a place where can goods and other groceries
are stored and frequently used and replaced. wire would be constantly
subjected to having something accidentally sat on it or plug accidentally
Option2) Place a UL listed plug on the end of the home wiring and plug the
microwave solidly into it. The plug will be in the hollow space in the wall
behind the microwave. In this location it will be the same as option one but
just hidden inside the wall in a nice safe location where it will never be
bumped, touched, or even seen by anyone.
You are telling me Option one is the better, safer, less likely to cause a
Actually, BOTH options are illegal here in Calgary. You can't put an outlet
inside of enclosed cabinet.
If your microwave has a normal plug, put an electrical box BELOW the cabinet
where the plug can reach. If the cord is long enough and you have empty
space above the cabinets, you could put the box there.
If your microwave is meant for direct wiring, the put a hole in the wall
behind the microwave an pull the electrical wire from the wall into the
junction box of the microwave (or a box put into the wall behind the
Is that what they really do up there? Doesn't this look like
hell? I guess you could try to route the cord so it's less
noticeable, but with excess cord, being in a grease prone area subject
to heat, etc, this sounds like a very bad idea.
