I notice that my salt system has three wires going in: two black and one green for 240 VAC.
Why no white common wire(s) like in 115 VAC?

Another question regarding L1 and L2 in a 240 VAC circuit.
Do all L1's have to be hooked to L1's, and all L2's have to be hooked to L2's?
For example, I have the power from the source going to the SWG timer, then down to the SWG control box. Should all the connections be L1 to L1 to L1, and L2 to L2 to L2?
