13A Switched Fused Spur with Neon - Anthracite (Part M Compliant)

The Knightsbridge 13A switched fused spur with neon indicator provides a switched, fused connection point for permanently wired appliances, behind an anthracite thermoset resin faceplate with white rocker switches and a red neon indicator. The neon illuminates when the spur is switched on, confirming live power is available to the connected appliance. The unit is fitted with a user-replaceable 13A fuse that protects the connected appliance circuit from overload.

Designed for fixed appliances such as kitchen extractors, bathroom fans, boilers, and under-counter freezers, the fused spur isolates the appliance from the main ring circuit while providing overcurrent protection via the internal fuse. The anthracite faceplate with white rockers provides the visual contrast required under Building Regulations Part M, with a Light Reflectance Value of approximately 8.9 that meets accessibility standards for residential and commercial installations. The anti-microbial surface treatment is tested to ISO 22196:2011, making this spur suitable for kitchens, care homes, medical facilities and other hygiene-critical environments.

The thermoset resin construction resists impact and thermal stress better than standard thermoplastic faceplates, and the screw-fixed faceplate fits a standard 25mm minimum back box depth. The 86mm square format matches standard UK single-gang switch dimensions. Knightsbridge backs this fused spur with a 25-year warranty, reflecting the durability of the thermoset material and the quality of the internal terminals and switch mechanism.

Product Specification Sheet

Product Manual

What does Part M compliance mean?

Building Regulations Part M sets accessibility standards for UK buildings, requiring visual contrast between switches and faceplates to aid users with impaired vision. This anthracite faceplate with white rockers provides an LRV contrast of approximately 8.9, meeting the requirement for contrasting elements to be distinguishable at a glance.

What appliances is this fused spur designed for?

The fused spur is designed for permanently wired appliances that require a switched, fused connection point separate from the main ring circuit. Common applications include cooker hoods, extractor fans, boilers, immersion heaters, garage door motors, and under-counter appliances. The 13A fuse rating handles loads up to 3,000W on 230V supply.

What does the neon indicator show?

The red neon illuminates when the spur is switched to the 'ON' position and live power is present at the load terminals. This confirms the appliance is receiving power, which is useful when the appliance itself is hidden (under-counter freezer, loft fan) or lacks its own indicator light.

Can the fuse be replaced?

Yes. The 13A fuse is user-replaceable and accessed by removing the fuse carrier from the front of the unit. Use only BS 1362 13A fuses as replacements. If a fuse blows repeatedly, investigate the connected appliance for a fault before replacing the fuse again.
