LV switchgear and surge protection should be visually inspected at least every six months. Routine LV maintenance should cover protection relays, batteries on load, auxiliary and timer relays, coils, terminations and mechanisms, shutters and contacts, including changeover mechanisms for the secondary supply; fuse-switches and isolators should be operated and inspected annually. All HV and LV switchgear and protection testing should be recorded on forms like the commissioning forms (Appendix 2). Good records let managers judge whether a test may be deferred, but three routine tests in a row is the most that should be deferred. Busbars and cables are inspected visually, aided by infrared scanning.
This control maps to 1 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 1 it maps to, and the evidence behind each claim, over MCP and REST.
