Have electric garage heater that I need to provide recepticle for.
the plug is 3 prong and shaped as follows two lower blaces ot 180
degrees and center is a round prong. sort of like this but with the 2
180 degree blades lower than the center round prong _0_
assume the 2 blades are to 120 v + and - legs while the center prong
goes to ground.
applience requires 30 amps of breaker so I will be using 2 15 amp
breakers and a 10 foot run of 10 gage copper.
