I have an electric unit heater given to a friend of mine who does not mess with things electrical. He wishes to install this in his garage. Although the nameplate is obliterated, I was able with optical aid to pull a model no. from it. It is A Qmark Model MUH072. No serial, no voltages, no current specs. It is wired 240 1Phase. Finding info online puts this unit at 31.3 amps at 240v. Wiring it in my garage shows that the unit is drawing 28.5 amps/leg with the fan motor on also. My question is, since I expect this unit to be considered continuous, If I run #10 thhn, and a 30 amp 2 pole am I doing things incorrectly due to NEC. 240.4 (D) (7). Thanks for any help.
