Help! Will this work (intermatic timer)

[LanesHortiMax]

Was looking for a internatic t101. Instead found a internatic t104R.

Was looking at this...found it for 27 bucks..new..local thrift shop...its double pole..single throw...208-277 VAC. All my ballast are 120v and will this work just as good as t101? Pics included....will this work? Says rated for ballast 208-277 VAC.

SHOULD I USE THIS?

The 101 is 120vac....was wondering even though this is 277 rated...would it still work for 120s?

If you download the instructions for both the T101 and T104R and compare the the wiring circuits, you can see how the timers are connected up. I believe that from a wiring standpoint, you can use the T104 on 120v; however, what is not clear is if the T104R Clock will run properly or at all using 1/2 the voltage it was meant for.


So with this uncertainty, I probably wouldn't use the T104R with 120v, I'd just spend an extra $25 bucks and get the correct one.

Spoken like a true brickweeder...thank you my friend.

the clock wont run right on 120.

Chunky is right ! The clock for the timer work on 220 (your clock will be offset)

It sounds like the switch is isolated from the clock, allowing the clock to run on 220 while the switched load is 110

^^ Just a link to a $4 wall wart that turns 110v to 220v for the timer part
