The notes
Exactly as they are on the site.
The fixed wiring and everything that forms part of it, from the supply inwards.
| In scope | Not in scope |
|---|---|
| The supply — service cable, cut-out, meter tails | Plug-in appliances and portable equipment — unless one of them is causing a fault on the fixed wiring |
| Earthing and bonding conductors | |
| Consumer unit, protective devices, switchgear | |
| All circuits, accessories and fixed equipment | |
| Containment, support and mechanical protection |
Start at the supply and work inwards. Incoming cable is usually concentric or PILC — paper insulated lead covered. PILC has a bitumen outer that, when it has been running hot over a long period, leaks and drips like black wax. That is a sign of sustained overloading, and it takes years to develop.
