How to Wire a 13 Amp FCU - Fused Connection Unit

How to wire a 13 amp FCU or fused connection unit. Sometimes referred to as a Fused Spur.
Fused spurs, also known as fused connection units (FCUs), are electrical devices used in wiring installations. They are commonly found in the UK and other countries that follow similar electrical standards. Fused spurs provide a means of connecting electrical appliances or equipment to the main's electricity supply while incorporating a built-in fuse for protection.
What are the benefits of fused spurs / FCU / Fused Connection Units?
Power control: Fused spurs enable control of power supply to specific electrical devices or appliances.
Fuse protection: Fused spurs have a built-in fuse, which acts as a safety measure to protect the connected device and the wiring from excessive current.
Connection point: Fused spurs serve as a connection point between the fixed wiring in a building and individual electrical devices.
Flexibility: Fused spurs can be installed with either a switched or unswitched configuration, depending on the specific application

Hi, just quick one, should the red light be on when the switch is on? I had a situation that with the switch on there is still supply as normal but red light is off. Thank you

Typically the red light should only be on when the switch is in the ON position.

Hi, Can I wire my spur box into the ring main, then supply my boiler from the spur box, thank you, great video, cheers

[@Builtbypete]

Yes, you can do that. I would suggest making it a fused spur for safety. 👍

@@Builtbypete brilliant, thank you chap

[@Builtbypete]

Your welcome

@@Builtbypete Would there ever be any point in putting a junction box into the ring main, then go down into the fused spur box then onto the appliance.

[@Builtbypete]

No, not really. That would end up just being the same as a spur.

Hi can I add fcu from fcu as the other spur socket is going out to the garden. Thanks

[@Builtbypete]

No I would not recommend adding them in series like that.
