I started a bath reno today and came across something that makes no sense...

30 amp. 240 volt feed for steam shower.. 12/2 running to mechanical timer...

BUT.. timer has 240v. across both terminals.. there would be a phase to phase short if timer was turned on.. :blink::blink::blink::blink:

Customer said unit worked.. I just can't see how....:blink::blink:

See post above.. I gave you wrong info...

There is only a 12/2 going to the switched part of the timer?




Edited; I see it is a mechanical timer.

Uhhhh...which terminals? If it's L1 and L2, you need to go back to school :laughing:


And, welcome back,.............. but I didn't know you were gone
No marking for L1 & L2.... only (2) brass screws on mechanical timer... :rolleyes::rolleyes:

Ah, you going to measure the amps over time ? Isnt's there a pump plus the
atomizer/heater in that thing?

IE The wire size seems small.

it can't.. put both legs of 240V together and you are welding.. :eek::eek:
Check a light switch when it is turned off, you will get 120v across the two screws.

It is the same principle.
