Sourced fact
A user test-button check exists only where the exact device or installation instructions clearly describe it.

RCD or RCBO labelled test-button check
Use a labelled Test or T button only when the exact device label, model manual or installer handover gives a clear instruction. Stop charging first, follow that instruction once at its stated interval and observe only whether the documented result occurs. If instructions are absent, conflicting or unclear, or the documented result does not occur, leave the chargepoint unused and call a registered competent electrician.

Key facts and evidence
For a UK home chargepoint, as reviewed on 12 August 2026, an RCD or RCBO user check is conditional on clear instructions for that exact installed device. Charging must be stopped, only the labelled Test or T control may be used once, and the observed result must match the supplied description. Any uncertainty or failed result requires a registered competent electrician.
Sourced fact
The permitted action is limited to one operation of the labelled Test or T control while charging is stopped.
Sourced fact
An absent, conflicting or unclear instruction, damaged control or unexpected result requires professional investigation.
Use a labelled RCD or RCBO test button only when the exact device instructions or installer handover clearly authorise the user check.
Why the exact instruction controls
The fitted protective device and chargepoint documentation define the relevant control, interval and expected outcome. A generic sequence cannot establish the result for a different installation.
What an unexpected outcome means
A missing or unclear documented response is not a user-repair task. The chargepoint remains unused until a registered competent electrician investigates it.
What to do next
Charging stays stopped while the expressly documented labelled-button check is performed and until its result is clear.
Immediate action: Find the exact device label, operating manual or installer handover instruction.
- No current instruction for the exact installed device can be found.
- The available instructions conflict or the intended control is not clearly labelled Test or T.
- The control is damaged, the documented result does not occur or the outcome is unclear.
Professional hand-off
- A registered competent electrician investigates any absent instruction, damaged control, failed result or uncertainty.
