Aloha from Hawaii: I just wired in a Model T103 24 Hr. dial time Switch, with the power source (line) hot to connection 3 and the neutral to connection 1, and the pool pump motor (load) hot to connection 4 and the neutral to connection 2. The manual on/off switch works just fine, but the timer itself does not keep time at all. What did I do wrong? Allan
Optional Information: Make: Intermatic Model: T103 Already Tried: Following the wiring diagram as I understood it.
You are corresponding with JOSEPH (The Electrical Doctor) - Your "Personal On-Line Electrical Consultant".This is a 220v timer correct?
No, this is a 120v timer.
It cant be, a 120v timer would not have a #3 terminal on it. Can you look at it again and verify exactly what all terminals you have starting from the far left to the right?
The terminals are: A - 1 - 2 - 3 - 4. The data sheet indicates 110/125 volts - 60 HZ.
Ok look closely at the terminals, you will see two white wires coming from the clock. Can you tell me which terminals they connect to?
The two white wires from the clock are attached to terminals A and 1.
Ok take your neutral from the incoming power and your load white and connect that to terminal A. Then connect the black wire from the power supply and connect that to terminal 1. Then take the black load wire and connect that to terminal #2. That will get you up and running.
