Go to your local electrical supply house and get 6-10' of 12/3SJ
cord and a 15A 120V straight blade plug unless you have a 20A 120V
straight blade on there right now. The difference is a 15A has 2
prongs parallel to each w/ground and a 20A has the 2 prongs
perpendicular to each other w/ground.
The formula for ampacity when HP is known is:
HP x 746 / E x Eff x pf
Eff=Efficiency (found on plate with voltage)
pf=Power Factor (also found on plate)
Wire size is limited by the plug. I suspect that you have a 15A plug
on there now so anything beyond 12 gauge wire is a waste.
Hey there, not to worry. For the six feet you are running to the wall
the original gauge will do (as it so far has done) fine. My gues is
that teh original cord was 14 gauge stranded and that such a
replacement would do you fine. No need to ask us, just take a section
of your old cord and strip it apart/down and count the wires and note
the colors and measure the wire gauge and be done with it.
Having said all that, LOWES and HD offer an "extension cord" intended
for an Air Conditioner that is likely 10GA (chop off the female end)
and may offer one or two that are 12GA and GOING DOWN never really
hurt anyone, right?
BTW, If you go long, you must go down!
