I fitted an electric shower for a Social Housing tenant in November.
The CU is in a built in garage, with direct access from the kitchen. The CU is close to the garage ceiling, with the bath floor around 400mm directly above it..
I fed it from the CU, to an isolation switch, in the garage, next to the CU, then out through the outer wall, in plastic conduit, then direct into the back of the shower unit. All sealed/glued, 10mm T+E, so no current carrying capacity problems, all RCD'd etc.
An outside Company has now done an EICR, and flagged up as a C2 that the shower has no local isolation.
I cannot see how it gets any Code at all. We use 2 different makes of shower, I can't remember which one was fitted.
One of the Manufacturers instructions say:
"The shower unit must be permanently connected to the electrical supply, direct from the consumer unit via an electrical isolation switch with a minimum contact gap of 3 mm. The switch must be readily accessible and clearly identifiable and sited out of reach of a person using the shower over a fixed bath or shower tray, unless the switch is pull cord operated"
The other says:
"A separate, permanently connected supply is taken from the consumer unit to the appliance through a double-pole switch. The switch can be a ceiling mounted pullcord type or a wall mounted switch in an adjacent room."
No. 1 is fully compliant I think.
No.2 (which I don't think I fitted) may be slightly against the Instructions as it says the isolator should be in an adjacent room.
Even so, I cannot see how a C2 has been seen fit to code this.
462.2 is met - Isolation is provided.
510.3 says "shall take account of Manufacturers instructions"
(510.3 used to say 'follow Manufacturers instructions", it changed in the 18th iirc)
Any thoughts on this, and have I missed anything, before I start arguing on Monday?
Thanks
Alan.
