Sample questions
01Which test verifies that a Type B RCD will operate on a smooth DC residual current?
- AEarth fault loop impedance test
- BInsulation resistance test
- CRamp test applied with a superimposed DC component
- DIntegral push-button test only
Why: A Type B RCD must be ramp-tested with a superimposed DC residual current to confirm it trips at its rated smooth DC threshold; the push-button only proves the mechanical trip.
02Which capability distinguishes a dedicated EV charge point tester from a standard multifunction tester (MFT)?
- AIt can perform an external earth fault loop impedance test
- BIt can simulate vehicle states and verify Control Pilot/PP signalling
- CIt can measure insulation resistance between live conductors and earth
- DIt can carry out continuity testing of protective conductors
Why: An EV adaptor or charge point tester can simulate the vehicle CP/PP states and verify the EVSE responds correctly, in addition to the usual electrical tests an MFT performs.
03What inspection interval is commonly recommended for a publicly accessible commercial EV charging installation?
- AEvery 6 months
- BAnnually
- CEvery 5 years
- DMonthly
Why: Public commercial charging installations are typically subject to a maximum periodic inspection interval of around one year due to heavy public use and outdoor exposure.
Common questions
Is the Testing mock exam free?
Yes — 100% free, no sign-up needed. Questions are pulled at random from a substantial bank, with a worked explanation on every question after you submit.
Can I retake the mock exam?
Yes. Every attempt picks a different random selection and reshuffles the options, so each retake gives you genuinely new questions. No limit on retakes.
Does this count towards the real qualification?
No — this is independent practice material. To gain the actual qualification you need to sit the official assessment through an approved provider.
