line cord can handle the voltage and load. seeing that this is a
plug you're referring to, it's assumed you are plugging it to a
proper 250 volt receptacle and the device it's connected to requires
250 volts?
remember, the plug is what is in your hands that you insert, the
receptacle is what's on the wall with the female insertion prongs.
If you're trying to branch off a couple of new circuits to get 120
from a 240 outlet, don't do that. the proper way is to use a sub box
with de-rated breakers from that circuit and not from the receptacle,
also this kind of system is not allowed where the possible use of
life saving equipment maybe depending on the circuit because if for
some reason the main breakers for the 240 tripped out, it would also trip out the 120 volt sub.
The code for that is very questionable to say the least.
I have a heavy line from the main panel going over to the work bench
that is #6-4 (red,black, white and ground), this gives me a 240 source
and i have a sub panel/breakers that gives me the 120 I need. The main
breakers for this line are 50 amps, the subs are 15 each.
I also have all of this in EMT pipe because it's low enough to be
reached by hands and code states it has to be covered some how. I guess
they don't think romix jacket is sufficient any more other than used inside an enclosure of some kind.
