I serviced a 30a 240v water heater for a home and found on the timer that someone had tied one 120v leg to the line and one 120v to the load on the incoming power, same on the output to the water heater. (has a 240 volt clock). Check voltage at the element before I realized this and it read 240v. I disconnected and bypassed the timer (cutomer didn't want it) still have the 240v of course. The customer said the water heater works a little better but still runs out of hot water too soon. The water heater is brand new and has 2 elements, both reading 12 ohms which is correct. The top element was on but the bottom one wasn't when I left. I know they have thermostatically controlled switches on both elements. So maybe the lower one is not kicking on when its supposed too?
