Warming Drawer Wiring

Posted by dahrich (My Page) on

Hello:
I want to install an electrical outlet next to a warming drawer. The wiring, Romex, must pass over the top of the drawer.
What does the Code say about this? Can I just run the Romex without any covering or must it be in conduit? My concern is that the drawer gets warm and may affect the Romex somehow.
The temperature inside the drawer may go to 220 deg F. I have no idea what the outside temp would be.

Thanks in advance.
Richard

You might want to post this in the electrical wiring forum. NM (aka Romex) must be protected from physical damage but it's a little hard to say if your situation falls under that rule. It's acceptable to use a short length of conduit to protect the Romex.

I'm less sure about temperatures. You might have to measure the ambient temperature around your warming drawer.

Hi:
Thanks for your comments.
I will turn the drawer on and see how warm the exterior gets.
I'll also repost

"I will turn the drawer on and see how warm the exterior gets. "

Your measurement is unlikely to satisfy an AHJ.

Call the manufacturer and ask.

The insulation in NM is 90C now.

The manufacturer of the drawer should be able to tell you what the exterior surface temperature is since they had to measure it to get the device approved and determine the clearance to flammable surfaces.

Hi: Manufacturer wasn't much help.
After turning the drawer on to max temp for a while I could put my hand on the exterior and it was slightly warm to the touch.
I think I will investigate routing the wire as far away from the drawer as possible.

Is the drawer returnable at this point?

Hi:
No I can't return the drawer and my wife would kill me if I even suggeted it. She loves it. It is our second one.

I have come to the conclusion that I can route the wires in such a way so as to keep them some distance away from the drawer. Also, I think there can't be too much of a heat problem otherwise the drawer power cord would be of very heat resistance material and it isn't. This conclusion assumes that most of the power cord is generally in the same enclosure as the drawer and heat from the drawer does not affect the cord.

Regards,

The installation instructions should say where the cord can be located.

"I think there can't be too much of a heat problem otherwise the drawer power cord would be of very heat resistance material and it isn't. "

Short of finding a temperature rating marked on the cordage you cannot tell the heat rating from a simple visual examination.

There is plain old zip cord available with ratings over 105C.
It IS slightly thicker, but that would be the only simple clue to its rating without looking it up.
