I have a new Stelpro RUH5-51T heater I'd like to 'safely' install in the garage. It's 240/208 v, 5000/3750 w, 50-60 Hz, 1 phase. The plate on the unit says 20.84 amps. Does this mean I can't use 12 gauge wire with 20 amp breaker? The run from the breaker box would be ~20-25 ft. Do I need to go with 10 ga with 25 or 30 amp breaker? The unit requires the green wire ground connection to the breaker box. Also, conduit protection, can I use flexible metal or do I have to use metal tube? THANKS!!!!!!

The safest way would be to call your electrician and let him do it. He will know what to use to make it safe.

You can use 10-2 with ground protected by a thirty amp double. I'd use 3/4 inch flex, but the job would be easier if you use THHN or THWN, instead of NMC with the flex.
