RCD Tester Calibration

We calibrate RCD testers used to verify the performance of residual current devices and ensure correct operation under fault conditions.

RCD testers are commonly used during installation, inspection and periodic testing to confirm tripping times and functionality of protective devices.

Our calibration checks relevant test parameters to help ensure accurate, repeatable and dependable results.

No booking required — just walk in. Many calibrations can be completed While-You-Wait, depending on workload, tester condition and specification.

Alternative options include our 24/7 drop-off safe boxes, By Post service, or Extended Hours & Priority Booking.

Simply update your business details — no booking required.
