Full details

Its primary benefit is providing a safe isolation point with easy fuse access, housed within a modern, unobtrusive screwless flat-plate design.

FAQs

What is a fused connection unit used for?

A fused connection unit, or fused spur, is used to connect a permanently wired appliance (like a washing machine, fridge, or boiler) to the mains electricity supply. It provides a safe isolation point and allows for a fuse to protect the appliance circuit.

Can I use this unit as a regular light switch?

No, this is an unswitched fused connection unit. It does not have an on/off toggle switch and is designed for permanent connections, not for controlling lights or appliances that need manual switching.

What size fuse should I use?

This unit is designed to house a fuse up to 13A. The specific fuse rating should be chosen based on the appliance's power requirements, as recommended by the appliance manufacturer or a qualified electrician.

Does this unit fit any standard back box?

It requires a standard UK 1-gang back box with a minimum depth of 35mm. It is designed for easy retrofitting into existing suitable back boxes.

What does 'screwless' mean for the front plate?

The 'screwless' design means that the front plate attaches to the unit without visible screws on the face. It uses a clip-on system, providing a cleaner, more modern appearance.

How do I clean the black nickel finish?

Clean the surface gently with a soft, dry or slightly damp cloth. Avoid using abrasive cleaning products or solvents, as these can damage the finish.

What is the warranty period for this product?

The British General Nexus Screwless Flat-Plate Fused Connection Spur Unit comes with a 25-year manufacturer's guarantee against faulty materials and workmanship.

Troubleshooting

Unit not powering connected appliance

Check that the 13A fuse is correctly inserted and intact. Verify all wire connections are secure in the terminals and that the correct terminals (Live, Neutral, Earth) have been used.

Front plate won't clip on/off easily

Ensure no wires are obstructing the plate. Check for any debris in the clipping mechanism. The plate should slide on and then be pushed gently to clip.

Tarnishing on the metal finish

Ensure the moisture gasket is correctly fitted during installation. Clean gently with a soft, damp cloth. Avoid installation in excessively humid environments without adequate ventilation.

Device trips the RCD/MCB

Verify correct wiring and that the appliance itself is not faulty. Ensure the unit is installed according to BS 1363 Part 4 standards. If the problem persists, consult a qualified electrician.
