I can't wait... so all that power will surge the house and melt that 14 wire I think... my father in law says the lower #'s are the tougher ones...
Well, 14AWG can handle 1800 watts, so thats a bit close to the draw you plan on, so 12 would be a wise choice. What do you plan to plug into this outlet? Also, make sure in a situation like this that it is GFI protected.
And whoever informed you that 12awg wire supports 360 watts is flat out wrong.
whe you need to determine what wire size, you start with how many watts you are going to draw. once you have that, you use a wire that can handle a larger draw than what you expect... as in 1600 watts x 120v = 13.3, so 15amps /14awg wire is what it would be up to. but theres not any wiggle room there, so i would go up one more to 20amp, which requires a minimum of 12awg wire.
the formula for wattage is amps x volts... in this case it would be 15A x 120v = 1800 watts, 20a x 120v = 2400 watts.
at 360 watts, that would be an amp draw of 3 amps. whoever told you that should not give advice anymore!
