Technical Specifications

The electrical, mechanical, and physical parameters of the MK 3PIN PLUG TOP 646WHI comply with standard UK Type G parameters:

Wiring Guidelines and Best Practices

Safety Precaution: Always ensure the main power cord is unplugged from the supply socket before performing maintenance or wiring adjustments.

• Conductor Preparation: Strip the outer sheath of the flexible cable cleanly without damaging individual wire insulation. Strip internal conductors to an appropriate length for insertion into the screw terminals.

• Cord Grip Tightening: Ensure the cable’s outer sheath is firmly clamped inside the automatic cord grip so that mechanical tension is not applied directly to the electrical screw terminals.
