10 amp lighting MCB

[Guitarist]

Is anyone using 10 amp MCB's with 1.5mm for domestic lighting circuits yet (as per electricians guide to building regs) or are most of you still going with 6 amp?

Wondered if anyone had come across any lighting switchgear not rated at 10 amps

hotel im working in has just had a visit from someone to look at their energyefficiency and any improvements that can be made His first thing mentioned was my fav things HALERS LED for replacing halogens and also the 2x26w thorn chalice type fitting now has an LED equivelent He said they also mention in passing on the report how LEDs pull less current than halogens hence create less hot spots in trunking,conduit systems

Shame they didn't just pay you to tell them the obvious

hi there just wondering any calculations for working out cable size. so example i have a 9.6kw shower what breaker and cable size do i have to use?
also with wired in smoke detectors can they be wired say off a socket circuit or a fused spur in use or does it have to have its own circuit?

thanks

I can't see you getting a shower on a lighting circuit unless you wired your lights in 6.0mm2. There are those who may try it.....

Maybe you're likely to get an answer if you posted this query on the instantaneous water heater forum

I would suggest getting an electrician to sort these jobs out tbh

same post on a different thread, you said you were competent. how can that be if you don't know the basics af calculating cable size from load and length of run?

Beat me to it Guitarist!

Questions such as this just proves you haven't even the smallest idea of electrical work.

I'm out:waving:

I personally use 1.5 for all domestic lighting i have never come accross a domestic circuit with enough lights on it to need more then 6 amp mcb although i have been in a flat with 2 pendants and 3 downlighters and that was on an 10 amp c type industrial breaker

Only ever used 10A when I was doing industrial and commercial work. In a domestic situation, if there is ever a reason to use a 10A, it's probably a good enough reason to provide an extra circuit.

harsh mate i only wanted advice! i am competent in electrics i just havent done certain things yet like that.. i know how to work out fuse rating for say the heater but i jsut wanted to calculation for the cable size id personally go for a 10mm cable for that 9.6kw shower. also with the smoke detector i just wondered if your aloud to run if off another supply say a fused spur? i have it on its own circuit anyway im just asking the question, thats what this site is for is it not!?

Personally i would use 10 mm for the shower and it is best to have thd fire alarm on its own circuit as it is a safety circuit but it use to say in some places that you can take a feed off a lighting circuit for fire alarm but not sure if that has changed

Whats this got to do with this thread?

We're talking about 10 amp MCBs not 10mm cable:waving:

Demkamp,
Keep going my son.....
Be determined......
and soon all will be revealed post by post, you'll be able to cobble something together with 1.5mm2, 6mm2, 10mm2....
There was talk once that if the conductors were superconducting (something to do with buckie balls) you'll be able to run the cables just under the wallpaper..

Im sure I've seen you ask this on another thread. Seems random to jump in with cable calcs for a shower when the thread is clearly 1mm lighting cable.

10?! 6?

For when you don't trust customers changing all those efficient lamps you just put in :icon4:
