Here's what I currently have: Whirlpool 20 gallon (1500 watt element) 120 volt water heater. My old tank was a 23 year old 3500 watt 240 volt water heater. Yes, I'm aware I can change out the WG1573 clock motor in favor of a WG1570. The wiring in the wall is 10-2.
This is what I want to do: With the existing 10-2 in the wall, I want to keep that wiring to the WH40 timer intact thus I can supply 240v power to the WG1573 clock motor. I want to run a solo (white) neutral wire from my service panel's neutral bus to the WH40's neutral tab "A". Run 10-2 from the timer - black on L2, white (neutral) on tab "A", ground to ground. Then run this to the water heater which is 120 volts. I will not be adding anything else to this setup.
And this is what I need to know: Is this acceptable? Or do I need to run 10-3 and do the exact same thing? Running a solo (neutral wire) from the neutral bus in essence allows the 10-2 wiring to become 10-3. I've tested everything and everything is as it should be. I just need to know whether there's code to back this installation up or as I just said, do I need to run 10-3 to have both a 240v and 120v connections coming out the WH40 timer from the service panel and to the water heater; thank you!
