Internal substations and switchrooms should have maintained lighting averaging 200 lux, escape lighting of 15 lux for 3 h supported by a secondary source, temperature kept above 10 C and within equipment limits, humidity controlled (it promotes partial discharge) and transformer heat removed, naturally where possible. As a minimum they should hold safety posters (including first aid and electric shock treatment), current single-line diagrams and, at the intake substation, a mimic board, a key cabinet with the site logbook, a sign identifying the LV earthing system (also at each final distribution board and MCC), a battery charger for trip circuits with on-load test facility, storage for tools and test equipment and fixed lifting equipment.
This control maps to 2 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 2 it maps to, and the evidence behind each claim, over MCP and REST.
