A 45 A switch with a 13 A socket hung off it — the isolator for the biggest load in a kitchen.
Defined in the glossary — each one opens at its own entry.
The switch is the isolator for the cooker circuit, so it has to be within reach of the appliance and clearly labelled — but it only isolates what is downstream of it. The supply terminals stay live with the switch off, and the load can exceed 40 A on a big induction hob, so the terminals must be tightened to the manufacturer's torque and re-checked after the first heat cycle.
