Immersion wiring question

Squaredude

I'm replacing my old immersion switch



with this new one



and was wondering if I need to do anything different with regards to the wiring?

Looking at that, the original wiring is incorrect. Looks like both bath and sink are on together when the bath/sink selector is in one of its positions.


What was the reason for replacing?

Switch started acting up and needed to be turned on and off a few times before it would come on and now it's not coming on at all. Any help would be appreciated

Could do with seeing clearer picture of old switch, it looks as if it's connected totally wrong to me

Its completely wrong.

The black and brown in the 4 core flex should be connected to L1 and L2 of the selector (2 way) switch. It would be best to also take a photo of the 4 core flex connections to the immersion itself to confirm

The link at bottom connecting L in to L2 should be removed, and used to connect L out to common.

First one is wrong yes.

Live and neutral from the supply(3 core) are ok.

Neutral from the 4 core is ok.

The brown link shouldn't be there.

L out should connect to common.

Brown and black should connect to sink & bath or L1 and L2

New switch will be the same

The way it is wired in the photo, both elements can be on together.

Would this be the correct way to wire the new switch? https://imgur.com/aIWYjZy

Yes

Although, cannot guarantee that sink and bath are proper way around

Yea when you switch it on, check the ESB meter while someone changes from sink to bath.

The meter should speed up on bath compared to sink. Easier to see with very little else running.

Success! And I didn't electrocute myself or burn the house down

Well done. I'd throw a clip or two on that flex onto a timber batton as near as you can to the switch.

There 's a lot going on with those main bonding conductors

There's a spare one sticking out and i see they've chopped the 10sq going into the clamp
