This Knightsbridge Switched Fused Spur Unit is designed for homeowners and electricians needing a safe and reliable way to connect high-power appliances or those without fused plugs. Its key benefit is providing a dedicated isolation point with a built-in fuse for enhanced safety during maintenance or power surges. A minor consideration is the requirement for a specific backbox depth.

A fused spur unit provides a safe and isolated connection point for appliances that do not have a fused plug or require a dedicated, fused circuit. It allows for easy disconnection for maintenance and protects the appliance and circuit with an integrated fuse.
Double pole switching means that when the switch is turned off, it disconnects both the live and neutral conductors of the circuit, offering a higher level of safety than single pole switching which only disconnects the live wire.
This unit requires a minimum backbox depth of 25mm.
This unit is rated for 13A and is suitable for appliances that do not have a fused plug or for high-powered equipment with continuous loads up to 13A. It is not suitable for appliances exceeding this rating.
The integral gasket acts as a barrier to prevent moisture from transferring from the wall surface to the electrical plate, helping to protect the unit and wiring from dampness.
To replace the fuse, ensure the power to the circuit is switched off. The fuse can typically be accessed and replaced by carefully opening the unit or fuse carrier, then inserting a new fuse of the correct rating (13A).
The neon indicator lights up when the unit is switched on and receiving power. It indicates the spur unit itself is live, not necessarily that the appliance is actively running, although this is usually the case when the switch is 'on'.
Check that the circuit breaker at the consumer unit is on. Verify the appliance's flex is securely connected and that the fuse within the spur unit is intact. Test the neon indicator; if it's off, check all live connections.
Confirm the main power to the circuit is active. Check the connections to the neon indicator terminal and the live feed. The indicator bulb itself may have failed.
This unit is fused at 13A and not suitable for appliances exceeding this rating. Consult an electrician for an appropriate solution, which may involve a higher-rated fused connection unit or direct wiring.
Ensure the cable conductors are stripped to the correct length and are not frayed. The terminal capacity supports up to 3 x 2.5mm² or 2 x 4.0mm² conductors. Loosen the terminal screws fully before inserting wires.
