I have been called back to a job where the pull cord is yet again not working. This is the sencond time they have had this fault.. Take the fitting down and the whole inside is a melted mess.. Now the shower is a 8.5kw fed on 10mm twin and earth on a 32a mcb. Install method B,

I have tested R1 + R2 and then R1 + and both exactly the same 0.07 which would tie in with the cable run. This is tested to the shower through the pull cord. ZS at shower = 0.50 (Testing with Metrel and thats the lowest reading on Loop)

Now i put the first one down do naff fitting but now im not to sure.. Has anyone else has issues with this.

Any idears fella's ?
 
try the crabtree 50A pull switch, and make sure the connections are tight. with 10mm there's a lot of strain put on the cables when you force them into that silly little patress that's designed for a mx. of 6mm.
 
Without a doubt, it's down to the connections mate. If using one which has to be pushed into place, make sure you push it up, then drop it back to re-tighten.
Your best bet is to use the Crabtree, as Tel suggests. This has a "wireable" base, then the lid simply screws on.
 
you have to be a lunatic to take 10mm to a ceiling switch ,
always wall box for me if bigger than 6mm.

Amen to that. I chuffing hate 10mm.

If a shower is protected by a clearly identifiable accessible double-pole RCD (which it will be to be compliant with current Regs), do you actually need a shower switch? (Reference to relevant Reg(s) appreciated.)

I mean if the RCD in question is dedicated solely to the shower.
 
Weird. I was thinking the other day it always seem to be neutral connections that burn out. Can't think of a reason as the IxR voltage drop is purely a matter of current passing through the joint, not voltage at the joint relative to earth.
