Customer Question

I have an intermatic EH40 water heater timer. It was installed In accordance with the instruction manual. now it just pops the breaker. Prior to this installation the old unit was by-passed by going direct hot to load (tied together). The water heater was on all the time.
I installed the new timer and now it pops the breaker every time. Ohmage on the elements is 25 ohms top and 34 bottom. Line power to the timer is 123 volts each side.
How can I isolate which item, timer or water heater is the problem.
Waiting to hear from you, Ron

Welcome. My name is ***** ***** would be glad to assist.

More details needed on the situation and setup, please.

First, what wires do you have from the circuit breaker? Colors?

What wire colors go to the water heater?

The water heater was working properly prior to this timer installation, yes? No?

Using the wire colors you will be providing, how are they now connected to the timer?

Call them LINE for wires from the breaker

LOAD for the wires to the heater

Let me know and we can continue,
