The Drummond G Clamp is simple and easy to use. The clamp-on design eliminates the need to drill busbars and provides a safer, reliable connection via a standard 4 mm socket. Ideal for connecting power monitoring and measuring equipment, the new colour coded clamps make phase identification easy. The spring loaded contact pin and locking ring ensure reliable results throughout extended logging periods.

The clamp can be tightened by hand when wearing PPE gloves. Eliminating the need to use tools in the busbar chamber.
Available in brown, black, grey and blue, the new design comes in both fused and unfused versions. The replaceable fuse is within the clamping screw providing protection at the source
