MK Grid Plus 20A Double Pole Boiler Switch - Grid Plus

A double pole switch disconnects both the live and neutral conductors of a circuit simultaneously, offering a higher level of safety than a single pole switch which only disconnects the live wire.

While it is rated for 20A, it is specifically engraved and designed for boiler control. For general-purpose switching, a different module from the Grid Plus range would be more appropriate.

MK Grid Plus is a modular wiring system that allows for a variety of electrical devices (switches, sockets, etc.) to be configured and mounted onto a common grid structure and faceplate.

The switch is rated for a maximum load of 20 Amps.

Yes, electrical installations, especially those involving boiler circuits, should always be performed by a qualified electrician to ensure safety and compliance with regulations.

Use a soft, dry or slightly damp cloth. Avoid using harsh chemicals or abrasive cleaners that could damage the surface or engraving.

Verify that the main power supply to the circuit is on. Check all wiring connections to ensure they are secure and correctly terminated. Ensure the switch is correctly seated within the Grid Plus frame. If the issue persists, the switch may be faulty and require replacement by a qualified electrician.

Ensure the switch module is correctly clipped into the Grid Plus mechanism. Check that the grid faceplate is securely fastened to the grid frame and the back box. Tighten any loose screws on the faceplate.

Immediately switch off the power supply at the main consumer unit. Do not use the switch. Contact a qualified electrician to inspect the wiring and the switch for potential overload or internal fault.
