High resistance upstream. Maybe just the circuit feeding the kitchen. Could be a fire hazard. Check it with a voltmeter.my microwave oven dims when I use it. I got a new one and it does the same thing. This is a old house and the lights dim when the refrigerator turns on. Can someone tell me what is wrong?
Funny, I would have thought that you electrical types (JOKE) would frown upon a 25 foot extension on a microwave cord. Yes, that's right. Turns out my entire kitchen runs on one circuit (except: oven 220 and garbage disposal - dedicated).You can put off the new circuit decision indefinitely by lengthening (by splicing) a power cord for one of these appliances so that it's long enough to reach an outlet that's on another CB.
You'll need heat shrink tubing and a soldering iron.
Leah. Pushing the envelope huh? :wink: I personally like to put the microwave and range hood on the same circuit. Fridge on its own. Then the counter top requirements.We just put a window AC in our kitchen. Turns out you cannot run a fridge, microwave, and AC on one circuit. :jester: Guess I'll pull a dedicated circuit this week.
Start laughing, please. Old microwave came with the house and was replaced because it only worked if you slammed the door REALLY hard. Turns out the plug was fried...Should that have been my first clue?How powerful is the new microwave? Old one?
Is it a 15a circuit ? 20a circuit?
What is your main panel, breakers/ fuses?
60a, 100a 200a ?
If you lengthen the cord to 25' you might want to go one click heavier on the cord AWG.Turns out the plug was fried...Should that have been my first clue?
. . .Means high contact impedance from a worn-out receptacle. . .
New microwave is 1250W Panasonic (120V) 12.7A [AC is Kenmore window 6000BTU listing 15A (115V)].
It's a 20A circuit running from the main panel (breakers) 200A.
I looked at the AC manual and it says, "A 115-volt 60 Hz, AC only, 15A fused and properly grounded electrical supply is required. A time delay fuse or time delay circuit breaker is recommended. Use a dedicated circuit, serving only this appliance." My emphasis.
Well, DUH! Maybe that's the problem. I guess I'll have to go buy some 14/2. Do you think it's a problem that I have three of these units running on another circuit in the house?:laughing: I guess they're rarely on at the same time. :laughing:
Modifying the microwave cord and plug will remove it's listing and is a direct violation. Same with your AC Leah. Your homeowners insurance would not pay the claim for this fire, should one occur anywhere in your house. Temporarily okay, but not for permanent installation. An extension cord is much better than a modified cord. It is compliant for TEMPORARY use only. I know it's hot, real hot.If you lengthen the cord to 25' you might want to go one click heavier on the cord AWG.
Whatever CB it finally lands on, you might want to alter the CB trip curve in the "time delay" direction.
