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:

I have no idea, but Im glad to see you back. :thumbsup:

Are they only switching 1 leg?

 

[B4T]

Are they only switching 1 leg?

No... they are switching nothing the way it is set up.. 120V on each leg.. 240V across both

 

[Awg-Dawg]

Yes....

If I am reading your question right,

It is back feeding thru the equipment.

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

We need the spec sheet!

timer has 240v. across both terminals.

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

Hi B4T

 

[Awg-Dawg]

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.

it will just close both legs....think of it as a dp switch...

No marking for L1 & L2.... only (2) brass screws on mechanical timer...

No feed to the timing motor?

Main unit has 30 amp. feed... 12/2 is the control going to timer...

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..

I am not turning it on.. really bad things will happen.. :no::no:

well...its not tripping the breakers and unit is or was working.something must be right...

Check a light switch when it is turned off, you will get 120v across the two screws.

It is the same principle.

How can you have both phases connected together.. :blink::blink:

I am thinking machine broke and handyman did some rewiring...

 

[Elephante]

The only problem I see is that the wire to timer might be undersized...did you turn on timer?
