Lights Supplied by 30 Amp Ring Final. B.S. 3036 Fuse.

Zoomup
HellOOOoooo All,


I came across a strange one today. I went to change a faulty touch dimmer switch for an ordinary light switch. I discovered that the two lights controlled by the switch did not originate at the lighting circuit, but from a 30 Amp wire fused ring final. The supply was connected to an old metal double socket box below the light switch, in an added conservatory, with a blank plate over it. I can not add a fused connection unit as the box is a double socket box. The blank plate is covered by a small easily removed panel convector heater. I was considering installing an inline fuse holder in the double socket box for the lighting circuit. The lamps are low energy types so overloading is very unlikely, but faults may occur.


Thoughts please.

    If the double socket is behind a radiator it might be missed by someone else if the fuse blew.

    you could fit an fcu at the light switch with front cable exit (possibly flat plate), then a stand off frame, then the touch controller replacement.

    Your 2x3A fuse arrangement might need a 2 sources of supply label in the fan.


    The blanked off double socket BOX is behind a small easily removable convector heater. The fuse could be missed but is the lesser of two evils. The circuit can not be overloaded as it only serves  two ceiling lights. The fuse would be there to protect from serious faults like rodent damage or nail bashing through cable.

    No; F.C.U. with flex outlet that you suggest would not be acceptable to the wife of the house. The single light switch is much neater.


    All common timer fans have a Permanent L and a switched trigger L. This is common knowledge. The manufacturers do not supply such a label so obviously consider it unnecessary.
