In this episode, I explain how to wire a switched fuse spur. Here are links to some of the components used in this episode:

Thanks. Saved me a few Bob.
well done 👍
Hi. Very good RUclips learning. Please advise if i) a switched fuse spur for a boiler should be 3 amp or 13 amp ? ii) if the former, would it be ok if the fuse spur's 13 amp be just replaced by a 3 amp fuse ? iii) how come my switche fuse spur just has one hole for Earth ? Many thanks.
Hi, excellent video. I have a question? I want to feed a small set of LED strips under some shelving and have the 12V transformer. I have identified a 30a 3 way junction box in the ceiling above which feeds the lighting circuit. Can I add a 1.5mm able to this and feed this to a fused spur > 12V transformer for the LED strips or should I stick with 2.5mm cable from the Junction box.
i have taken a double spur from ring circuit and fixed a 13amp geyzer switch to it and used it to add 6 extra double spurs for my items of aquarium tank including heaters filters etc..and wired them with 2.5 wires..i did ok or not??
Hiya ! I have one of them in my Attic and not working would a 13amp blow it? I think the fuse went and it was a 13a I put another 13a in but never worked I am in Scotland so same electrics as you not Europe.
Quick question. I have a fused switch fitted and second wire goes to outside light. I want to change light and run a new cable. I removed the fuse and cut the wire. Do I need to turn off electric when I’m fitting new wires? I know it’s dead as I cut the old wire but is there anything live if fuse is out when fitting new wire?
Thank you for your comment. It's good practice to isolate the electrical power at the breaker. To be safe, disconnect the electrical power at the fuse board by turning off the breaker. Measure the voltage with a multimeter to ensure it is safe and remove the fuse at the spur to ensure the load (i.e. light) is disconnected from the power. Remember 30mA can kill someone so always protect yourself. Seek professional advice from a qualified electrician.
Good vid. Is it dangerous to rig a light straight from a 3 pin socket to a rocker switch and then to a ceiling light bayonet holder, or is it best to use a cable from the 3 pin socket to a SFS as the light switch. Thanks
Most light switches are only rated for 6 or 10 amps and depending on your location, the socket could be on a 20 or even 32-amp breaker or fuse. So you have to fit a fused spur.
Nice video
Thanks

What would cause it to start bussing room flickering On off
Due to risk of damage in a garage, especially if DIY jobs done there, I would not be using plastic boxes and face plates. I would be using something like the MK Metalclad switched fuse spur.
How come your using a fused spur for lights
The switch isn't rated for the 20 or 25 amps of the socket circuit supplying this setup. You could use the spur itself as a light switch though, at least in the UK.
@@Ragnar8504 Hello recently went to my loft and found that my spur has 2 red wires going into the supply. I understand that one runs from the socket to power the switch, that power my lights. However the second red and black wire run to another FCU and that powers my boiler. Do you know if this is the correct connection?
@@dakkan5433 It doesn't sound ideal, although it might be OK, depending on the size of the cables and fuse/MCB protecting the cable. If you're concerned, have an electrician look at it!
@@Ragnar8504 It isn’t in my opinion, the wires are over 50 years old! They are not even close to 2.5mm. I have no clue who was doing the connections but 3 wires for 3 separate bulbs oh dear...Looks like something I’ll be doing for the next month after work
