Description
The Knightsbridge JB0013 is a 3-pole IP68 weatherproof inline connector rated for 24A at 250V/450V, designed for joining or extending outdoor and underwater electrical cables without tools. The connector uses lever terminals rather than screw terminals, allowing cables to be inserted and locked by hand without needing a screwdriver or stripping tool. Two M22 cable glands at each end accept cable diameters from 5mm to 14mm, providing strain relief and environmental sealing.
Designed for outdoor lighting circuits, garden power distribution, pond and water feature wiring, and underground cable runs, the connector pairs an IP68 rating with a flame-retardant PA66 body and a silicon sealing gasket. The IP68 certification means the connector can be submerged in water beyond 1m depth for extended periods without moisture ingress. The silver-plated stainless steel lever terminals maintain conductivity in damp environments and resist corrosion better than bare brass terminals.
The connector measures 122mm long and 25mm in diameter, with a cylindrical black body that sits inline with the cable run rather than requiring a separate junction box. It accepts HO7RN-F 3G cables from 0.75mm² to 2.5mm² cross-section, covering most UK outdoor flex and armoured cable sizes. The operating temperature range of -30°C to +85°C allows the connector to function through British winters and summer heatwaves without the seals failing or the PA66 body becoming brittle.
The lever terminal design speeds up installation compared to screw terminals, particularly when working outdoors in wet or cold conditions where fine motor control is reduced. Each of the three poles is isolated within the connector body, preventing phase-to-phase contact even when the connector is fully submerged. The barometric pressure tolerance of 86-106kPa confirms the connector can be used at typical UK elevations and in pressurised underground conduit runs.

Frequently Asked
Can this be used underwater?
Yes. The IP68 rating certifies the connector for continuous submersion beyond 1m depth. The silicon sealing gasket and M22 cable glands prevent water ingress when the cable entry points are properly tightened.
What cable sizes does it accept?
The connector accepts HO7RN-F 3G cables from 0.75mm² to 2.5mm² cross-section, with overall cable diameters from 5mm to 14mm. The M22 cable glands provide strain relief and environmental sealing for cables within this range.
Do I need tools to fit the cables?
No. The connector uses lever terminals rather than screw terminals. Insert the stripped cable end into the terminal opening, then push the lever down to lock the cable in place. No screwdriver or crimping tool is required.
What's the maximum current rating?
The connector is rated for 24A at 250V/450V. This suits most UK outdoor lighting circuits and garden power distribution runs, which typically operate at 6A-16A.
