Can 2 chest freezers be plugged into a 100' extension cord and freeze properly?
Use an oversized AWG cord, e.g. #12, #10 AWG to avoid voltage drop in the cord. I guess each unit needs 5 amps for total of 10 amps when both run at once.
With a 14 Gage cord (0.5 ohm @ 200' wire) and with both units starting up at same time, the current (amps) draw is 60 amps (6x running current) and 1800 watts, the 1800 watts consumed by the cord, this power dissipated as heat. The 1800 divided by the 60 ( watts/amps = volts) years a voltage drop of 30 volts, at start up of the two compressor motors if at 5 amps flc (full load current). This scenario with a 14 gage, 100' cord is problem bound so a thicker wire cord is needed to keep voltage drops within 10% of the load's rated voltage. Use a 10 or 12 Gage cord or two separate cords.
