Fit Socket off boiler switched fused spur for cctv cameras

[Donetello1561]

The switched fused spur was originally for the immersion heater,so I’m assuming it’s a radial circuit,cable running to it appears to be 1.5mm t&e.This is now running the combi boiler as well as the receiver box for the wireless stat
Proposing to add a socket at the side of it with a four way extension lead to power 4x cctv cameras,have read various conflicting posts that say this can be done and can’t be done.
Taking the new cable to the new socket from the out going load side of the fused spur.
Is this correct?

Will be ok but I'd fit 2 x twins and avoid the extension lead.

Need to know the size of cable and protective device, you say 1.5mm but it would usually be 2.5mm.

Also the circuit would have to be rcd protected.

Sorry for not replying yesterday got caught up with something else.
Looks like the boiler fused spur is the only thing the cable runs to,it’s on the RCD side of the dis board with a 20’amp breaker.Still not sure it’s 2.5mm though.
There is a 3amp fuse fitted,remove and replace with 13amp fuse then run the new 2.5mmmcable from the load side to the 2 new 2 way sockets ?.
So you think two doubles would be better than running a four way extension lead.

That is a (switched) Fused Connector Unit; the cable is the fused spur - if it is a spur

You can't do that if the 3A fuse was necessary for the boiler cable - although it probably wasn't.

then run the new cable from the load side to the 2 new 2 way sockets ?.

If it is 2.5mm² cable on a 20A MCB you can run 2.5mm² cable from the feed/supply side and leave the 3A fuse for the boiler.

It doesn't really matter electrically.

Thanks,I’ll check the cable size somehow.

It’s definitely 2.5mm cable and there’s nothing else on this cable accept the fused unit to the combination boiler,reading contradicting posts on wether this work needs to be signed off by a spark,
As you said it would be straight off the supply side to two double sockets with a maximum of 2 foot of cable and only powering 4 x 12v cctv cameras.
Any additional outlooks welcome and thanks for the reply’s so far

Ok, (if 20A and 2.5mm² cable) you can connect as many sockets as you like.

Well, it needs testing and the results might as well be recorded. So if you do it you are the spark, so the answer is yes.

 

[Donetello1561]

Done,just needs cables tidying up,and someone to test it.
Any ideas on cost and time to do it?
