I have left the hyphens out because the parts that I am referring to are normally live but insulated by a cover.
I was working in a bungalow today. The consumer unit is situated at high level just below the ceiling in the kitchen. Below the consumer unit is a tall storage cupboard. When I used my steps to turn off an M.C.B. I noticed that the long plastic bus-bar cover that is normally inside the consumer unit was left out on top of the tall storage cupboard. Also a modern energy meter had no cover on it and the four terminal screws were visible. The screws are partly recessed by 2 or 3mm but are still touchable if you put you finger against them. I suspect the solar panel installers are to blame.
So, the owner could be searching for an item stored on top of the tall storage cupboard and get a nasty shock. I suspect that the cover meant to cover the live meter terminals was dropped down the back of the fixed tall storage cupboard.
Bad all round.
