Probe your electrical safety system to make sure it's in good working condition with this RCD tester from Megger. It simulates an earth leakage to check how your device responds and if it trips the circuit. The built-in ramp testing feature lets you pinpoint the trip current of your RCD, so you can tell when nuisance tripping is happening with the wrong current flow. You can also use this handy piece of kit to measure frequencies between 25 and 450Hz.

It has a voltage accuracy of ±2% and a frequency accuracy of ±0.1Hz for measurements between 25 and 199.9Hz. An accuracy of ±1Hz when measuring frequencies of 200 to 450Hz means you can be sure of all-round precise measurements.

You can set the polarity check of this tester to 0 or 180° to test how safe your live and neutral wires are.
