Socket & See CB400 Non-Trip Installation Testing Calibration Checkbox
The Socket & See CB400 Non-Trip Installation Testing Calibration Checkbox performs reliable installation checks, ensuring test equipment meets current wiring regulations. The CB400 is capable of checking six insulation, three loop check, five RCD and five continuity levels (plus checks installation testing correct output).
The CB400, featuring a useful null facility, operates correctly with all leading makes of Insulation/Continuity, Loop and RCD testers regardless of multifunction or single operation. Designed to be exceedingly user friendly, simply plug the checkbox into the mains supply before connecting your equipment and recording the results.
Contained within a tough, drop-proof watertight case for use on site and easy carrying capability, the CB400 offers compliance to – BS EN 61557 Test Instrument Requirements.
