Shower Isolator

[Brilec]

Have to do a job next week that involves fitting new shower, cabling isolator and standalone shower CU, as unable to update old main CU. Question is they don't want a pull cord as an isolator, loft space is not really possible, they would like a switch for shower on wall by door, Inside the bathroom. This would be 2 metres away from shower and mounted aroundabout top of door height, having looked at the regs, it seems that this would be ok but would like others opinions

Equipment should be installed in line with the regs and the manufacturers instructions, they almost always ask for a DP Isolator you would beon thin ice if someone got an asswinder and it couldn't be isolated quickly, besides which DP isolated circuits are belt and braces (No nasty N borrows) and you won't achieve that with an mcb only the MS or a DP RCD

There will be a DP isolator in the CU so thats covered......I always fit a local DP isolator where possible,but did do one recently where it wasnt practical so used the separate 1way CU at the intake.

I think the boys above are referring to the use of the MCB as isolation, which obviously isn't DP. The main RCD/SW in a CU should not be used as it would affect several circuits (referring to your 1st statement. Obviously different if a 1-way CU).
