shower spur???????

[macloon]

I know that showers should have an independent fuse, but was wondering if it would be possible to spur off the shower feed with a fused switch connection for 1 light above shower region. I would extend the lighting circuit but problem is the bathroom is below a flatroof and the joists run the wrong way to feed a cable over to desired area and the floor is tiled and cant be disturbed.

As it is only 1 light and shower is only 8.5 kw dont have to worry about overloading fuse, any advice would be much appreciated

hmmmm u sure you not on about commercial/industrial

regs are regs ipu, wherever installed.

no. as i see it, he must come off in 6mm or 10mm ( whichever it is) to his spur, then fuse down to 1.5mm cable to the light.

 

[i=p/u]

yes maybe but you could come off busbar of any rating in 2.5mm for socket circuit as long as fused within 3m

The two regs are below

What about reg 433.2.1 or even 433.3.1(ii)

go on tell me please,

no. as i see it, he must come off in 6mm or 10mm ( whichever it is) to his spur, then fuse down to 1.5mm cable to the light.

433.2.2 allow us to position the protective device along the run of cable, providing certain requirements are met. So no branch or outlets between reduction and protective device.

The cable before and after the protective device also requires fault protection, so the shower fuse would need to provide fault protection to the reduced cable upto the fuse, and dependent upon the fuse and csa it may provide after the protective device too.

Not always! Account for a 6mm run off a 1600A feeder to the 4A fuses for metering.

yeowwwwwwwwwwwwwwwwwww, someone understands

I am not disputing that this can be done but maybe I am from the old school and probably an old foaggie stuck in the past but I was always taught that shower and cooker circuits were dedicated and to break into them or spur off was to introduce a weaker link in other words 2 connection one at the board the other at the switch.

Mind you now that I am reading this post I will be more aware that someone may have spurred off it

Don’t shoot me if im wrong!


But i have never seen a FCU or socket outlet ect with it moulded on the back that it will accept a 6/10mm cable or in the instructions. Yes you prob could terminate them in one, but for me I think if some think went wrong with said “bodge” the manufacture would not stand by you(I could be wrong). There for not installed to manufactures instructions ie not covered by regs! And i think cooker would be the same.
