There is no problem in spurring off a fused spur (I think that’s what you mean). The principle is you just need to protect the cable. This week I’ve seen a unfused spur from a socket on the ring to a single socket (in 2.5 6262Y) – then from the single socket to a FCU in 1.5 6242Y for the boiler.

Can you take a spur from a spur?

The easiest way of connecting into a ring circuit is to run a spur cable from the terminals of an existing socket – but you can’t connect it to any socket. The IEE Wiring Regulations are very specific about this. You mustn’t run a spur from a socket that’s already on a spur, or that already supplies a spur.

How many times can I spur off a spur?

5 Answers from MyBuilder Electricians Ok if it is all fused through a 13 amp Spur unit then you can have as many as you want, but limited to 13amp total. It must be off of a radial or a ring circuit as I can’t think of another type of power circuit. If it’s off of a radial though it’s fine.

What happens if you take a spur off a spur?

The reason for not running two spurs from the same spur “point” is that it can lead to possible overloads in that one leg of the final can become unbalanced and exceed the max. allowed amps for a bit of 2.5mm if the tap off point is near the cu.

Can I spur off a fused spur?

You can but you may risk overloading that spur causing the 13a fuse to blow what is your intended use for your garage sockets and your conservatory.

How many sockets can you run off a fused spur?

you can have maximum one double socket as a normal spur but if you are going from socket to FCU fused at 13 amp from there you can add as many sockets as you wish as all the sockets and cable will be protected by the fuse so no chance of overloading the cable the fuse will blow first.

Can I use a plug instead of a fused spur?

“The regulations state that the appliance needs to be fused, either with a plug or a fused spur. … So as long as the plug sockets are accessible without touching the appliance to turn it off then this is fine, but also a fused spur is fine too.”

How long can a spur cable be?

The maximum length allowed for an unfused spur is 3m. The general rule of thumb, is that you can have an unfused spur at each socket, and one at the CU.

How many sockets can be on a spur?

How Many Sockets Can Be on a Spur? Only one spur can be connected to a single socket.

Can I spur a light from a socket?

You need the neutral to make the light work but you can take a spur from the socket underneath the desk for a light, you could place a FCU next to socket underneath desk then run cable to light switch and then on to light fitting .. you cannot run spur to spur with sockets incase of over load of cable but a light is …

How many sockets can a spur have UK?

A spur can be connected to an existing socket, on either a ring main or a radial circuit, providing that socket does not already have a spur. That is only one spur per socket is allowed and the number of spurs must not exceed the number of sockets.

What size cable do I need for sockets?

2.5mm Twin and Earth is commonly used as indoor domestic cable. The most common use for this type of cable is for circuits that provide power to sockets. It is made up of two cores and an earth core which must be covered with the identifying green and yellow sleeve when installed.

Can you have 2 fused spurs off one socket?

Only one fused spur may be taken from any socket on a ring. From that fused spur you can have as many electrical outlets as you like, as they are then protected by the fuse.

Can I run a spur from a cooker socket?

Course you can spur off a cooker circuit, so long as cable reductions are fused accordingly.

Does a washing machine need a fused spur?

Fused spurs are commonly used as an alternative to a conventional socket, for the installation of powerful electrical appliances that can be installed without a plug, such as ovens, washing machines, electric heaters, dishwashers, fridges, and so on. …

Does a combi boiler need a fused spur?

Current regulations require your new boiler to have an electricity supply from a fused spur, as this ensures that when an engineer carry’s out routine maintenance on your boiler, there is no danger of electrocution.

Should a boiler be plugged into a socket?

A boiler can be either connected via a switched fused connection unit (spur) or an UNswitched socket outlet – not a switched socket outlet.

Can I install a fused spur myself?

As long as the job isn’t within a ‘special location’ such as a bathroom or outdoors, you’re also allowed to install additional new light fittings, switches, sockets and even add a single fused spur to an existing circuit (a ‘spur’ is a new cable and socket run as a branch from an existing socket on the ring main).

Can I put a double socket on a spur?

A spur can feed one single or one double socket or a fused connection unit.

Can I spur off an outdoor socket?

You can wire an external socket in the same manner as a normal spur, by running the cable from a socket or junction box on a main ring circuit (via a switched connection unit) and mounting the socket on an external wall. Ensure your circuit has RCD protection, and that you use appropriate weatherproof outdoor fittings.

What is an unswitched fused spur used for?

An unswitched fused connection unit could be used for any appliance that has its own ON/OFF switch, such as a washing machine, or a device that operates continuously and must be difficult to turn off, such as a fire alarm or security lights.

How long can a 2.5 mm spur be?

It should be wired in 2.5mm2 P.V.C./P.V.C. T&E cable. There is no limit to the length of a spur, but Voltage drop considerations should be taken into account. It is not recommended that large loads like immersion heaters, large space heaters or similar loads be connected to the ring final circuit.

How far can I run 2.5 mm cable?

A good rule of thumb for ring finals wired in 2.5mm is that the total length of cable used should preferably not exceed 100m. In certain circumstances a larger total cable length may be admissible, but such circumstances need careful consideration.

How far can I run 6mm cable?

2 Answers from MyBuilder Electricians The maximum length of cable for your circuit is 62 metres.

Can I run lights and sockets be on same circuit?

Yes of course, for example desk lamps and other loads can be on the same circuit. However, there’s usually a special circuit for lighting because lighting pulls very little current, and so much thinner wire can be used, and so a separate lighting circuit is cheaper to install.

Can you spur a light off a ring main?

Running additional lights of ring main through fused spur is normally OK but not primary lights unless unless also emergency lighting is installed.

Can you spur off a lighting radial?

A standard radial circuit can be extended from any point or points that provide a permanent live, neutral and earth without worries about having a spur off a spur or extending the ring.

What does a spur do electrical?

Spur – An electrical supply using one feed cable to a socket taken off a ring main usually used to achieve an extra socket without having to do too much work. See also Fused Spur.

What is an RCD spur?

An RCD fused spur is typically used to install hard wired appliances that require residual current protection. … RCD fused connection units feature a trip button to manually reset and are commonly installed to power bathroom pumps, towel rails and heaters.

Can I use 1.5 mm cable for Ring Main?

Use 2.5mm twin and earth cable for all single and double sockets as 1.5mm cable can only handle 14 to 20 amps at 230 volts. It is common for 1mm and 1.5mm to be used for radial lighting circuits, and 2.5mm cable is normally used for ring main wall sockets.

Can I use 1.0 mm cable for sockets?

Yes, 3 core is required for 2 way lighting circuits. Personally i always use 1.5mm t&e for lighting, but either 1mm or 1.5mm is ok.
