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 ...

Over the length of a 2' long cord, I don't think you could measure the voltage drop with a 12 amp load running through it.
Once I was parked in the pits at the Bowling Green Raceway, and had a #14 extension cord 50' long plugged into a 15 amp receptacle, with no fuses in sight. To that I plugged in a #12 25' cord, then a adapter to my 30 amp 25' extension cord, then my voltage booster, then the RV 25' long cord. From there, some 15' of #15 wire leads to the circuit breaker box, and another 25' leads to and from the inverter/charger with transfer switch.
Anyway while under load of the air conditioner on a 90F day, the voltage dropped to only 108 volts while being boosted by 12 volts! So I double boosted it back up to 115 volts! I can only guess how many amps where going through the #14 cord to the booster, then about 15 amps out of the booster. Voltage into the booster must have been around 92-95 volts?
Anyway the short small cord can work. The microwave will be fine. . .
