Need confirmation on the wiring of this digital timer

I am replacing a Tork 1103B with a Intermatic FM1D20A-120

The new timer wires different then the older dial style
I assume the wiring is as follows but I am asking confirmation as I don't want to destroy an expensive switch

1. Hot (Black) (from the circuit breaker panel)
2. Neutral (also goes unbroken to the load which is two neon signs)
3. Hot (which is pig-tailed from the same hot wire at terminal number 1)
4. This is the wire that goes to the hot (Black) wire of the neon signs
5. Not needed

The two signs are actual neon (with a Neon Sign Transformer) and it is a 120V 15A circuit

Thanks in advance and let me know if anymore information is needed

Yes..... you have it correct.
The Tork had a common hot connection. Didn't require the #3 jumper you need now.

I finally got the timer wired (per the diagram on post #1 ) and all is well the timer works fine.

Thank You for the confirmation that my diagram was correct

OK these timers keep failing on me


The first one was physically burnt the second one just stopped working.

The specs say 12A ballast (which I assume a Neon Sign Transformer is considered a ballast?)

I don't know how many amps the signs draw but there is 2 big signs each with a standard magnetic Neon Sign Transformer.

Do you have any recommendations for a better timer?

Preferably a sturdy and reliable model (Probably a mechanical one as those seem to be better built and can handle more loading)

The original Tork 1103B had a problem with the gears or another plastic part failing, I don't remember the exactly method that they failed but it was a plastic part

Unfortunately I can't do a photocell without re-configuring the wiring as the timer is in the electrical room of the building

Thanks

I've always leaned towards Intermatic timers.
I think those neon sign transformers are around 400-500 watts. 4A or so each. The problem is the high inductive load when they connect that causes the contacts to arc. You could use any basic timer and a contactor for better power handling.

Talking

Do you have a favorite Intermatic model? I know what a contactor is but I have no idea on how to select the right kind or how they are wired. So I think I will just stick to a standard heavy duty timer setup

I've used cases of the Intermatic T101. It's like an industry standard. Single pole switch/120v clock.
