Heat resulting from voltage drop?

Microwave cable goes (from MW cabinet) through the hole in the MW cabinet wall to the receptacle in the adjacent cabinet. No receptacle in MW cabinet. A straight plug sticking out in my cupboard, not even a flat plug, - how stupid is that?

I'm tidying things up and thinking to put a short 2ft extension cord that has a low profile plug and a cable exiting at 4 o'clock. They don't come in 14 AWG, only 16 AWG.

V-drop @14A will be 0.22V. Correct me if I'm wrong, this is a heater with 0.22*14=2.8W. Seems like nothing to worry?

    Cut it off and replace it with a 90 degree angle plug - done, with no need for any adapter of any kind. :)

    The design (Plug in next compartment) makes more sense than you can imagine if something goes wrong.

    I have even shorter cords I can use. How much tribble 2.8 watts will be I do not know. but that looked like a 3' cord.. and 3' makes it less than 1 watt per foot.
  • I have the same basic arrangement in my S&B house: the microwave/hood plugs into an outlet in the cupboard above, and takes up a good bit of otherwise useful space. I've thought about building a little shelf or something to make it less obnoxious, but have not gotten around to it yet.

    16 gauge would probably be OK, but marginal. Most extension cords will have labeling on them or their packaging regarding their maximum current ratings, although sometimes disguised slightly as "up to xxxx watts". I think the Home Depot web site (where you were looking at this) usually has that information listed.
  • What in the world is the big deal about the plug on the end of the cord??
    Are you going to be able to put one more coffee cup in there ?
    There are a few things in my MH that are a lot stupid'er than that.

    Otherwise move the receptical into the microwave cabinet, only to find out the MV won't fit! Now that mite make it on my list of stupid stuff :)))
  • My gut feeling is: You will be trading one "eyesore" for another one and the coiled up extra cord will end up being more problematic than the plug sticking out from the wall a bit.

    I would NOT use an extension cord that is lighter gauge than the one the manufacturer has attached......on anything.

    Simply putting a different style plug on the end of the existing cord might be a better solution.
  • Unless you're running it for an hour, I wouldn't be concerned.
  • If having company makes you feel any better, my setup is just the same with a straight plug in the cabinet. The power to my microwave is probably pretty typical: 25 foot shore cord, romex to the breaker box, romex to the slideout area, connector transition to flexible cable, transition connector back to romex in the slide, another connector where the romex comes out of the slideout wall, finally romex to the outlet the microwave is plugged into. Sometimes I'm surprised the darn thing works at all! It's all 12 gauge. I'd feel a bit uneasy using even a 14 gauge run. You could always cut the plug off the existing cord and replace it with an angle plug. They're not as slim as the one in your picture, but a lot better than the straight plug.
