What Does the Term ‘Gang’ Mean?
The term ‘gang’ is used by electricians to refer to the length of the electrical ‘box’ (that familiar white rectangle) which houses spurs and sockets. ‘1 gang’ is large enough for a single socket or fused spur, while, as the name suggests, ‘2 gang’ models incorporate a pair.
What is the Difference Between a Switched and Non-Switched Fused Spur?
Switched fused spurs include a button which allows users to switch off the current to the unit. This can be achieved either within the live line only (single pole spurs) or in both the live and neutral lines (double pole spurs).
What is a Spur Circuit?
A spur circuit is an electrical circuit that runs between a fused spur and the main electrical supply to a building. It operates independently, as a separate branch of the ‘ring circuit’ which runs between all the devices on-site using conventional plug sockets.
How Many Sockets Can Be on a Spur?
Only one spur can be connected to a single socket. In other words, the number of spurs in a particular location must not be greater than the number of sockets to which they are connected. The purpose of this is to avoid the risk of overloading the connected cables and causing an electrical fire.
What is a Double Pole Fused Spur?
A double pole fused spur is a switched model which features an extended isolating mechanism that breaks or connects both the live and neutral wires within the device. It provides a good level of protection from accidental exposure to electrical current.
How to Wire a Light Switch from a Fused Spur
If you wish to wire a light switch to a fused spur, you will firstly need to ensure that no other spurs are already connected to the socket you will be using. Choose a spur with a suitable current rating - normally 3 or 5 amps for a light switch. You can install either a switched fused spur, which will also function as the on-off button or an unswitched fused spur alongside a conventional light switch.
How Do You Wire a Fused Spur?
In a fused connection unit, you have two supply terminals – live supply and neutral supply. You also have two load terminals – neutral load and live load – as well as the earth terminal where you connect both wires. To complete the wiring, you will need to connect the wires coming from the mains or ring circuit to the supply. You then connect the wires that are going into the fused spur to the load. As always, if you are unsure, it’s always best to consult a qualified electrician prior to carrying out the task at hand.
Can I Change a Fused Spur to a Socket?
This is only possible if the unfused spur is no longer actively functioning on a spur circuit - i.e. if there is no independent connection outside the main electrical circuit.
