I figured it out...I do NOT want to have to buy a 120 volt water heater timer or a new 120 volt clock motor. The 23 year old water heater I removed is a 240 volt tank; thus from the service panel to the timer and then to the tank was wired 240. I discovered over the past few days, there are a number of options available. One, was to buy a 120 volt water heater timer like the Intermatic T101 or just the WG1570 120 volt clock motor or re-run a 10-3 wire to the timer which has a neutral and that's the key to all of this. One web site suggested run a single neutral wire from the neutral bar to the timer and while that works, what I don't know is whether that's code. I temporarily took some 10-2 peeled back the hot and the ground and screwed the white neutral into the panel at the neutral bar and ran it loose to the "A" tab on the timer, turned everything on...I have 240 going to the clock motor and 120 going to the water heater; problem solved! It's just a question of how to run the wire. Do I run a new 10-3 to the timer through the wall or under the house and back in or take only the white neutral wire and run it from the neutral bar that basically goes from 10-2 to 10-3; I just don't know if that's code, which I've got bets it's not. It does work, I have 120 volts going to the water heater; I just need to know; thanks!
