My question is not quite in the title.
I've been asked to quote for the above. No extraneous conductive parts in garage, which I intend to supply from spare way in house domestic CU, swa to garage CU utilizing the earthing facility of TN-C-S.
However, one of the reasons they want the supply installed, is to power a portable heater in their mobile caravan that they winter on their driveway, to combat damp etc. Not quite sure of the exact nature of the heater (not a caravan'er myself), but assuming normal low voltage heater on a trailing lead.
Sec 708 electrical installations in caravan parks, Sec 721 electrical installations in caravans.
Reg 708.411.4 ESQCR prohibit the connection of a PME earthing facility to any metalwork in a leisure accommodation vehicle, but not sure where a portable temporary device would fall under these two regs.
I could see the potential of flex to heater being damaged, and standing on true earth and holding onto metalwork of caravan.
Phone my scheme Elecsa, who just referred me to 708.411.4. I could just install and advise against, or go for TT in garage, but is my thinking correct? I suspect they've done it for years, with flex from the house.
