IEC 60309 uses colours to indicate voltage ranges, with yellow for 100–130V supplies commonly used on UK construction sites via transformers, and blue for 200–250V single‑phase supplies often used for outdoor equipment and caravans.
Sockets and Plugs for Indoor, Site and Outdoor Power
Sockets & plugs in this range cover everyday 13A BS1363 outlets and adaptors, along with site‑ready IEC 60309 connectors in blue 230V and yellow 110V colour codes, plus accessories such as coax plugs, blanking plates and replacement screws. These products suit repairs, upgrades and new fits across domestic and light commercial settings, while the industrial connectors support temporary power on sites and events. For charging and small devices, 2 Gang Switched Socket with USB Outlets offers integrated power and data, using the fused UK plug and socket system defined by BS 1363.
For outdoor use and wet areas, weather‑resistant housings help protect connections against rain and spray, and many buyers look for IP66‑rated enclosures and 30mA RCD protection for added safety. Portable power distribution is easy to extend with Extension Leads and reels when working in gardens, workshops or on temporary tasks, while blue 230V and yellow 110V plugs follow IEC 60309 colour coding for quick voltage identification. Switches complete the circuit with matching faceplates and finishes for a consistent look across rooms.
Installation typically involves choosing the right back box depth, with 25mm working for many standard fittings and 35mm or 47mm preferred for slim “flat plate” styles or USB outlets. Pairing outlets with suitable boxes such as a 2 Gang Pattress Box 47mm maintains cable bend radius and screw clearance, and supports neat flush finishes. Where outdoor power is required, IP66 housings and RCD protection at 30mA are commonly used so lawn equipment and tools can be powered safely from fixed outlets or compatible reels.
Sockts & Plugs FAQ's
IP66 is widely used for exposed outdoor sockets because it is dust‑tight and protected against powerful water jets, and these outlets are typically paired with 30mA RCD protection for additional safety.
Many flat‑plate or USB‑equipped sockets specify 35mm, sometimes 47mm, to accommodate the electronics and allow safe termination space behind the faceplate.
BS 1363 plugs contain a replaceable cartridge fuse sized to protect the flexible cord. Typical ratings used in households are 3A for lower‑load appliances and 13A for higher‑load items.
A small flat or PZ screwdriver, wire strippers and a sharp blade are usually sufficient. Connect brown to LIVE (right pin), blue to NEUTRAL (left pin) and green/yellow to EARTH (top pin), keeping insulation right up to the terminals and clamping the outer sheath under the cord grip. Fit a 3A fuse for loads up to around 700W, or a 13A fuse for higher‑load appliances; always match the fuse to the appliance rating shown on its data plate.
