His calculation has slight problems on the elctronic side. He did basic calculation but that is not how it works in the real world. In the heater there will be some form of small electronic board which convert the voltage to a very high voltage and will only need may be one or two amps [some time only milli amps], thus one has to be very carful what you put in the FCU because it can damage either the heater or other equipment connected to it.

I’m currently studying being an electrician. My training says to switch 13A fuse for a 3A fuse in the FCU, and also new practice is now to use 1.5mm cable
Thank you so much. You helped me out big time. Now I know where to add a fused spur. I love the way you draw it all out and explain everything so patiently. Thank you once again. 🙏
I was thinking of doing exactly as illustrated for a range hood, was unsure to meet BS regs. Your video has given me that surety. Thank you very much. I have subscribed to your channel. Cheers.
Very clearly explained, made it easy to understand. I have fault on my Under Floor heating and I think it is blown due to builders using 45A DP switch.
I'm currently dealing with a fault on a spur line and this is an excellent explanation! You have enabled me to isolate the fault to the switched live out! Good work! ****
Thanks. Helped me with telling my kitchen fitters that one 13amp FCU isn't the correct connection for washing machine, dishwasher and tumble dryer and telling me to only have one on at once isn't very professional or acceptable. Apart from it being dangerous as the fuse melted into the fuse holder when too much power was asked for.
Hi, that's exactly what I needed. But some said you can have the FCU from the ring, not from socket. which is correct? here is what I found: " Can I run a fused spur off a spur? So basically a spur of a spur is never permitted, even if its fused. I'll have to just stick in a juntion box in the ring cables under floorboard and get a fused spur off that. Put a 13amp unswitched spur adjacent to the socket, then you can run whatever you like within reason from the outgoing or load side of that."
Question. I'm adding a dishwasher to my kitchen. I was just going to add a socket under the counter. Is it an absolute requirement that I install an FCU above the counter as well, or just a nice-to-have?
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??
So at 5.0 the kitchen diagram does the fcu come off the ring main at each of the sockets, ie a wire from a socket on the ring to the fcu and then to the socket for the washing machine. A wire off the second Socket on the ring to an fcu and then to a socket for the dishwasher and so on.
Great presentation.answered a question that's been nagging me about a little job I have to do. However... yoirvideo f***ed with my head ,I thought I was having a migraine as there is a yellow bar running vertical across the screen, thought I was seeing things. Anyway,great video.
Hi, quick question. If I wanted to run two double sockets and a light off a FCU how would I go about that. Would it be 15a fused spur off the ring main socket. Then double socket 1 spur off FCA, then double socket 2 spur off double socket 1, the 3-5amp fused spur off double socket 2, then light switch off 5amp FCA, then light off light switch?
I assume this would also work with a single breaker box right? So If I wanted to bring power to the shed I would wire the connection from a socket inside and move it to the shed and connect it with a breaker box and then connect the sockets, lights etc from the breaker box?
Good video and I agree that there can only be one unfused spur per socket on the ring. Having said that, surely, though maybe not the best idea, two 2.5kw heaters plugged into a double socket should be fine. (2 x 2500watts) / 240volts = 20.83amps, with both sockets rated 13amps and the wire is rated 26amps. If any of those went on fire then surely they weren't up to standard. The rating should be the safe limit with a safety margin calculated in.
Can i wire. 4 block extension directly to a fused spur? Inhaveva fused spur that used to supply a fire. Fire removed and media wall going in. To avoid channeling and mounting sockets and have location flexibility wondered if that was an option?
Hello, What are the regulations/correct way of wiring a Beko built in oven rated at 2.3 KW and the cooker hood? Can I used 2 FUSED spurs each wired back separately 2 a dual 13 amp socket? Can I feed them both directly from the back of the 13 amp socket? Will there be enough room in the socket to terminate the hood and the oven? Do I have to wire them both separately?
In the kitchen, I have a standard double gang socket for kettle and toaster. The airing cupboard in the hallway on the other side of the kitchen wall, I have a washing machine. I would like to take power from the socket in kitchen, drill hole through wall into airing cupboard and wire a spur socket from the one in kitchen for the washing machine in airing cupboard. So basically, 1 washing machine on a single gang spur, kettle and toaster in kitchen from socket that is feeding the spur. Would this be ok please?? Thanks
Hi, great info, Just wanted to know, can you spur 2 times off the fcu, Eg Ring socket >fcu+spur in one room, then from the fcu to another room adding 2 more sockets So the fcu will have the 2 2.5 coming in then 2 2.5 coming out, 1 to the socket in room 1 then 1 going to the other room adding a 3rd socket, Any help much appreciated
Can I use one of these to isolate a 2 gang socket and 2 ceiling rose lightbulbs in the outside Toilet (connected to the house) from the kitchen socket?
Do the maths. How many sockets have you got in the first spur. Lets assume a twin socket - so allow for a poss 3Kw per socket - so 6Kw being drawn off the first twin socket. As you then have a max of a 13amp fuse load after that - the downstream load can be a max of 230x13 = 3Kw. This gives a potential draw of 9Kw / 39amps on the first leg of the spured cable. This is much higher than the standard 2.5T&E is really capable of supporting and will melt and burn. The Fused spur swtich should be before any sockets so it is able to limit the cable load to 13amps / 3Kw - or lower if you use a 5amp fuse .
I have a spur twin socket with cable buried in the wall. I want to run another spur with low consumption from this spur. Can I put the FCU after the first spur and before the second one?
No! The point, is that the FCU must be installed BEFORE the two sockets on the spur. Otherwise the 2.5 mm cable priour to the first socket could still be overloaded. I presume your spur is a double socket, thus, one way around it might be to use a twin box that allows two single sockets to be fitted to the box. The first socket could then be the FCU, the second on the same box a single socket, then spur off that socket to your next socket. I'm not a proffesional electrician. So research yourself to verify. But the point is you need the FCU first. You also need to remember that those two sockets are limited by the 13 amp fuse in the FCU.
I have a question may sound stupid , if I have a single socket I don't need can I convert that into my iso switch and then run the cable into another two double socket?. So then that becomes my isolation point cause I for say don't want that socket anymore..
Hi, i have a question! Probably silly but what if i dont want to take the cable out from the socket but instead want to use a 3 pin plug, can i still follow the same example for fcu? Im trying to add a cooker hood and washing machine but the plug is far! I dont want to take it of a socket so instead i wanted to create a extended socket with a 3 pin plug but add a fcu in between. Is that ok to do?
Very informative videos. Thanks for making them. I have a question. I live in an old house, there's sockets only on one wall. There's 2 outlets 2 light switches and an fcu that is connected to the water heater for the bathroom. I want to have a socket on the opposite wall. The closets connection is the fcu. Is there a way to run a cable or buy a different fcu so I can add an outlet from there without having to switch it on, as that will switch on the water heater.
Hey can you take a live feed from the fusee box to another fused switch to my outdoor socket only I have 2 feeds for the ring and already spurrd to another fused switch going to outdoor lighting. I dont want 4 lives going into 1 connection from a plug socket 😒😒 thanks
What electrically is the difference between the unfused spur in the beginning and a radial? If you can use 2.5mm to do a radial with basically unlimited sockets why can't we use just 3 sockets here?
I have an fcu (5amp ) serving a light switch for spotlights. I want to add a double socket off the fcu. I assume I replace fcu with 13 amp fuse and wire the connection for the double socket to the fcu using the supply terminals ?

Hi so I have added a fused spur off the ring and added 2x 2 gang sockets but it keeps tripping the mcb for down stairs sockets could you help me please
If using a fcu 13amp connected to 3 switches can you connect a separate cable into the same fcu and power 3 sockets? If so then can you put in an additional fcu 5amp to power lighting straight off the 13 amp fused sockets?
Hi, can another feed be taken from the FCU for a separate socket please? The FCU is already supplying 2 spur but would make my work easier if I can take the feed from the FCU. Thanks
Hi, thanks for your really helpful videos. I wonder if you can help me. I am replacing a spurred socket with 2 FCU's. One FCU to connect to 3 new double sockets, and the second FCU to connect to a new LED batten and one-way switch. When I remove the original socket, there's just the one 2.5mm Twin & Earth cable. How can I connect that to 2 FCU's which will be situated next to each other? Do I need to go back further down the original spurred socket cable to the socket on the ring, and feed two 2.5mm Twin & Earth cables to the 2 FCU's?
Do you mean two spurs from the same socket on the ring? If so, absolutely not. As you would have too many conductors in the terminals of the socket on the ring. Plus, theres no point.
A lower rated fuse will work fine. Indeed when these are used to supply things like extractor fans, cupboard light and so on, this is normal practice. However, if this is a fused spur for sockets there's not much reason to use anything other than 13A
You can use and should use a lower rated fuse if using a conductor of a smaller size. 13 amps is for spurs from ring main with 2.5 mm twin core and earth.

On a radial circuit. Can I source of of spur off and feed under floor heating load 900 watts.
David Patheyjohns you can have unlimited amount of fused spurs. 900 watts equates to just under 4 amps. So, yes, you can.

These fuse switches say 13 amps on them, can a 4 amp fuse be put in or will it not be able too work.
