FAQs
What is double pole switching?
Double pole switching disconnects both the live and neutral wires simultaneously when the switch is operated, offering a higher level of safety compared to single pole switching.
Do I need a special backbox?
Yes, this socket requires a backbox with a minimum depth of 25mm to accommodate the components and ensure a flush fit.
What is the purpose of twin earth terminals?
Twin earth terminals provide a more robust and continuous earthing path, essential for installations requiring compliance with specific electrical regulations like BS 7671:2008 regulation 543-7.
Can I use this socket outdoors?
This socket is designed for indoor use. While it has an integral gasket for moisture protection, it is not rated for outdoor environmental exposure.
How do I clean the screwless plate?
Wipe the plate with a soft, slightly damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the matt white finish.
What are the dimensions of the socket?
The dimensions are approximately 87.5mm (Height) x 147.5mm (Width) x 4.3mm (Projection). The recessed depth is 31.5mm.
Is this socket fused?
No, this is a switched socket and is not fused. Fused connection units are separate products.
Troubleshooting
Socket not powering connected devices.
Check that the circuit breaker is on and that the wiring is correctly connected. Verify power at the source.
Switch feels stiff or loose.
Ensure the screwless plate is correctly and firmly attached. If the issue persists, contact a qualified electrician.
Gasket appears damaged or ineffective.
Carefully inspect the gasket for tears or compression. Replace the plate if the gasket integrity is compromised.
