I usually just use a 4 pole contractor with 2 n/o contacts and 2 n/c contacts.

Use a seperate light switch at one shower to operate the contractor.

Not sure thats legit as it doesn't mean two showers can't be run at the same time.

Could you give me a link to this contractor if you have it. If not maybe the make and model no
Thanks

It is impossible to run the two showers at same time as only two poles of contractor can be closed at any one time.

It is totally permissable to use this method

Sorry yeah I see that

You actually don't need an isolator at the shower with the control switch as the contractor provides separation.

I always put it in anyway☺

It can be a useful way to have a priority setup alright, but for isolation, it needs a proper isolator at each shower. A changeover contactor is a fiddly isolation method imo.

I installed a change over contractor arrangement myself in the distant past. I did this because the priority units had been known to fail (at the time). As stated above it made impossible for both units to run at the same time.

Can you tell how that works.

When no control power is applied only "shower A" can be energized. When control power is applied on "shower B" can be energized. A 2 way switch arrangement is used to select either shower, with one switch outside each bathroom.

A light switch. It was only switching a low current as it was just for the coil of the contractor. It was a 2 gang, the other switch on it was for the bathroom light.
