Im trying to wire a sauna heater. Im using #12 wire as directed in the instruction manual (directions say 3x12awg 12.5 amp). The wire I purchased has 4 wires in it, two hots, a neutral, and a ground.
Here's the diagram, which confuses me:
Is the neutral not required for this application? One hot in L1, one hot in L2, and the bare ground into slot 1 with the ground symbol? If this is the case, do i just leave the neutral wire not connected to anything?
