Hi there. I've wired 240 for the garage, everything works on a 15a basis, lights etc. Now I'm installing the G73 heater, and everytime I turn the breaker on in the garage, detached, it trips the breaker in the house. I'm using a 30amp breaker in the garage, and a 40amp breaker in the house. The unit call for 30amps, however on an amp meter, it's tripping in the house on 7.6amps? The red and black wires from the breaker in the garage are wired to the L1 and L2 ports, the bare ground from the garage panel is wired to the ground screw in the dayton unit, and the white wire is not utilized...what am I doing wrong to trip the house breaker? I've tried different breakers, larger breakers...everything trips the house breaker. Please help.
