new ensuite shower room

[devonred]

Evening all,
new to all this so please bear with me.
I am building a new ensuit to out bedroom. Part of the build includes new low voltage spots and a new timmer fan (screwfix). In have fitted this set up in the past but must confess to being a bit flumuxed by circuit diagrams I have got from manufacturters. Can anyone tell me, in terms I will understand, how to wire the fan, lights, isolator and light switch.
Thanks in advance

Have you checked diagrams at head of these post re standard wiring configurations? These will show how a ceiling light is normally wired.

power comes in on one cable. I presume you will need to get one from an existing light fitting. Then the red half of another cable takes power to the switch. Probably a pull switch mounted on the ceiling. The black half takes power back to the light.

The light is connected between the black coming back from the switch, and neutral. Neutral is the black from the cable bringing in power.

The fan needs connections to live, switched live and neutral. Use a cable with three insulated cores. This goes to a three pole isolating switch and on to the fan. The fan should have separate terminals for live, switched live and neutral.

All earths should be sleeved in green and yellow sleeving and connected together where cables meet. Switched live (a black) should have red sleeving on it to identify it. (or maybe brown if its new coloured wiring)

But whatever you do, if you are working in a bathroom, remember parts F,G, H and N of the building regulations.

Oh right. Heard a rumour it was something about life saving. Don't people say the stupidest things?

Yeah, right.

Like to see Johnny spending a mill to cut deaths on the rail network Ha f*****g Ha.

The only other thing he's spent a mill on is his two loves, Jags & Pies.
