What it is

An outlet that incorporates earth leakage detection in the socket itself, so protection sits at the point of use rather than at the distribution board.

When a local device makes sense

A socket in a wet area remote from the distribution board

Refurbishment where running a protected circuit is impractical

Temporary or added circuits

Circuits where the risk is concentrated at one point of use

Points to check

Sensitivity and trip time

Whether the outlet is rated for the load connected

Whether it is provided with overcurrent protection upstream

Labelling so users know the outlet is protected and testable
