UK Steel plate?

[Johnstar]

This is in a flat, the plasterboard at the back is the bathroom wall surface. Is it appropriate to protect the incoming and tails with a steal plate fitted behind the DNO board? Worry about penetration form the bathroom but also Eddy currents and heating of a steal plate. Obviously the CUs will be changed.

Anyone drilling /fixing should be aware of what may be behind, especially as they'll have the C.U's a a big clue.

Not needed / impractical to do.
To be fully effective you'd have to pull all the plasterboard off and put plate in all the cavities above where the cables pass through.
It's more likely that someone would but a screw through the cables in the timbers with holes in.

Thanks, I’m not to worried about the cables after the CU because they will be protected by a RCD. The incoming cables are from below and I was proposing to fit the plate behind the DNO board, just release the board and slide the plate behind. Would it cause a code on an EICR do you think. Cables <50mm deep.

 

[Johnstar]

I wouldn't worry about it install them so they are 50mm+ from the board.

Thanks, so as long as they are >50mm from the bathroom side it will be acceptable?
