Thermal insulation and cables


Postby stratman » Fri Nov 23, 2007 6:00 pm

Hi folks in DIY land

I have tried seaching buthave not found a definitive answeer to this one. By regulation, is it just heavy draw electric cables, such as shower and cooker, that should not be covered by roof insulation or is it all cables?

Thanks all

HI stratman,
When cables are run through loft spaces where thermal insulation is required, the cable where ever practicable should be fixed in a position so it will not be covered by the insulation. When it is covered certain cable calculation need to be need made, which will alter the size of cable being used do to a reduction to it's current carrying capacity. So I would clip the cable above the installation if and where ever posible. This applies to most cables.
Kind Regards, Hope info Helpfull.
