Can I do this..... go my doubts...?

[sythai]

Hello only me again...

Got bathroom coming up and customer wants to try and limit the number of switches / isolators.

Ne ed a switch for lights, DP switch for fan and also need FCU for towel rail....

Was thinking a 4 gang grid set up would be nice, but am I allowed to have 2 different circuits in there, lights and FCU on the ring ?

Thank u,

Sy

 

[telectrix]

are you using an in line fan?

 

[sythai]

Not on this one.... would do normally but no loft access... why is that then ?

 

[Spudnik]

Im guessing you are installing the switch outside the door?

 

[sythai]

Thats the plan all outside the door......

 

[telectrix]

fan isolator can go at ceiling height outside.

 

[sythai]

Sorry wasnt to clear.... they just want the fan on an on/off switch next to light switch (there's no overun, so just L+N double pole will do).... as opposed to usual come on with the lights and isolator over the door, didnt explain it very well first time round

 

[electricians]

You can put 2 circuits in the same switch plate

 

[saabuldin]

You can do that only if fan and switches are outside zone 2 unless the fan is low voltage.

Having separate circuits in one switch box is ok as long you don't mix the wires up by taking power from one circuit to the other

 

[sythai]

all out of zones.... so thats good thank u

Could you not use the ring circuit to power the light and fan in the bathroom(fused down at the switch) then there is only 1 circuit in the switch.

 

[Spudnik]

Just as a side note, i think you dont need an overrun fan if the room has an opening window.

 

[telectrix]

surely you can feed off the lighting circuit for both light and fan, link lives on 2 gang switch, one switch for each

Yep thats the plan.... then it leaves the ring circuit fused down which I was going to run the 800w towel rail off

If there is a window, no isolator required for fan.
I know, I know, its a silly one and too be honest, I always put an isolator.
Sythai, why not put a motion sensor activated fan. That way, it works without the need for lights to be switched on and you can adjust the time.
I have fitted these at a few places and they look smart as well.
Best regards,
