Wiring of 45A Shower Control Unit

[ian2012]

Hi,

The light in my bathroom is connected via a 45 Amp Shower Control Unit (diagram). I am having difficulty understanding how the previous owner connected it (get the feeling it was a bad job) as I need to replace it. It is also connected to an extractor appliance.

Hope someone can help me out on this!
Cheers,
Ian

I can't make out what's going on from that photo - looks there are a lot of conductors apparently not connected to the switch, and at least one switch terminal unused (the N Supply), which makes the conductor in the N Load terminal a tad pointless.

And there's what looks like blue. black and green/yellow cores twisted together with bare ends exposed.

In short it's a b****y mess.

I hope it is only being used as a light and fan switch, even though it's a shower isolator....

Where abouts is this switch and how is it isolated/turned off?

The poster has obviously taken the Neutral conductors out of their terminals for clarity. This is a shower isolation switch that has been tapped to supply the light and fan, connections made at the supply side of the switch to provide a permenant supply.

OP, it's up to you whether you want to reinstate as is.......or connect your light and fan to your lighting supply and have only the shower running from this switch as its supposed to.

There should be one red and one black on the supply side (from the CU) and one red and one black in the load side (to the shower). The other two reds and blacks belong to the fan and light.

Didn't succeed.

Looking at it again using higher magnification I can see that's not the case.

Sorry.

Let's hope it's a shower pump, and not an electric shower...
