At present the Consumer Unit, along with a switch-fuse, is mounted in a box (around 300mm x 700mm) on the internal leaf of an outside wall. I should like to recess the box into the inner wall leaf to give more elbow space in the surrounding area. The white meter box, which has long lost its meter seals, is about 500mm along sideways on the outside wall.
Can find no bar in the regs to this re-arrangement. The tails would actually finish up slightly shorter. Any snags known?
Would ply (WPB) 18mm thick make a strong enough new back for the box or do I need something thicker? (Box sides are timber)
