A multi-occupier building has, in a communal service cupboard, a
single standard 13A surface-mounted switched socket into which is
plugged a normal-looking plug.

Entering that plug are two different leads connected to two
different items of low-power fixed communal equipment (it is
not easy to see what each of those actually does - or did.

How should that setup be described, on a scale running from
entirely satisfactory to absolutely illegal?


It's likely the wiring in the plug is untidy. I suggest two plugs and an
adaptor. Fit 2A fuses in the plugs. Check that the cables don't pull at
the adaptor unduely. Check that the equipment has adequate ventilation.
Consider a smoke alarm in the service cupboard, near a ventilation
grille (of a type that won't close) in the door.

What you describe is commonly done by cowboy CCTV and TV system persons.
