This link shows the distribution for outdoor and hallway lights (through the timer) and TV amplifier in a block of flats. http://tinyurl.com/7pryqdp
As in thread title, does the arrowed switch box have a fuse in it?
Further comments:
~ The fuse before the meter is 100A
~ The tails from the meter are rather thin rubber/fabric covered
~ The TV amplifier is fed by the white T&E between the switch and black connector box. The cable terminates in a socket just before the amplifier
~ The switch box receives its earth down this T&E
~ The black connector box has an earth going into it (seen under the black cable) for the switch and TV and hence to the socket but the box itself has no continuity to earth
~ One of the sheathed cables is used for the landing lights (the other no longer used). Since the connector box has no earth, the sheaths are not earthed.
~ The active sheathed cable goes to a metal junction box on the 2nd floor to branch to the landing light and an outdoor light through T&E.
I am wondering what I should discuss with an electrician? Obviously make sure of earth continuity. Presumably replace the switch with 2xRCBO enclosure. TV amplifier and socket as 20A radial. Lights through an immersion heater timer, perhaps?
