16A 2P+E Industrial Plug 110V - Yellow & White IP44

The Knightsbridge IN001 is a 16A 110V industrial plug with a two-pole plus earth (2P+E) configuration, housed in a yellow and white impact-resistant body carrying an IP44 rating. The plug is designed for connecting portable tools, machinery and temporary power distribution equipment to 110V centre-tapped earth supplies, common on UK construction sites and in industrial environments where reduced voltage improves safety.

Rated at 16A on 110V supply, the plug handles loads up to approximately 1,760W. The IP44 rating provides protection against solid objects greater than 1mm and splashing water from any direction, making it suitable for outdoor use in light rain or damp workshop conditions. The yellow colour coding follows UK industrial convention for 110V equipment, helping prevent accidental connection to 230V mains. The plug accepts cable through a rear entry with an internal cable clamp, and the body screws together for field wiring or re-termination.

The plug measures 122mm long by 51mm diameter, with brass contact pins and a screw-type earth terminal. The white body section provides grip for insertion and removal, while the yellow face section carries the pin assembly. The impact-resistant polymer body withstands drops and knocks typical on active construction sites. Each plug is supplied with a small cable gland to secure the cable entry point and maintain the IP44 seal.

Product Specification Sheet

What voltage does this plug operate on?

This plug is rated for 110V centre-tapped earth supplies, commonly used on UK construction sites and industrial settings for safety. It is not compatible with standard 230V domestic mains.

What does IP44 mean?

IP44 means the plug is protected against solid objects larger than 1mm and against water splashing from any direction. It can be used outdoors in light rain or damp conditions, but should not be submerged or used in heavy downpours without additional protection.

Can the plug be re-wired in the field?

Yes. The body separates via screws, allowing access to the internal terminals for field wiring or cable replacement. The cable entry includes a gland that must be correctly tightened to maintain the IP44 seal.

What cable size does it accept?

The plug typically accepts cable diameters suitable for 16A rated flex, usually in the range of 6-10mm outer diameter. Refer to the specification sheet in the Downloads section for exact cable gland dimensions.
