Electrical Safety Testing

Verification tests on installations: continuity, insulation, earth and RCD.

The problem

New and existing installations must be verified to show they are safe to use. Tests confirm that protective measures work as designed.

Measurement required

Continuity of protective conductors, insulation resistance, earth electrode resistance, RCD trip time and current, and polarity.

Instrument type

Instruments conforming to the relevant parts of IEC 61557: insulation/continuity testers, earth testers and RCD testers.

Relevant Kyoritsu instruments

Listed because their documented specifications cover this measurement. Check the full specifications for your exact requirement.

Measures AC leakage current with 0.1 mA resolution.

IEC 61557 insulation and 200 mA continuity tests.

IEC 61557 insulation and 200 mA continuity tests.

Earth resistance testing to IEC 61557-5.

RCD verification and socket wiring check.

How to choose

Select instruments that cover the tests your standard requires and record results in a form your reports need.

Safety considerations

Follow the test sequence in your standard: dead tests first (continuity, insulation), then live tests (earth loop, RCD).
