Main Isolator Label

This Main Isolator label identifies the primary isolation point for an electrical installation or a defined section of the installation. It provides electricians, service technicians and authorised personnel with clear switchboard identification.

Typical applications

Suitable for switchboards, distribution boards, solar installations, plant equipment and other electrical systems with a designated main isolator.

Simple, unambiguous identification

Main isolation points should be easy to distinguish from circuit breakers, submain switches and equipment-specific isolators. Position the label immediately adjacent to the correct device and avoid placement where it could reasonably refer to more than one switch.

Confirm the designation

Where multiple supplies or main switches are present, a more specific label such as Grid Supply, Normal Supply, Generator or Battery may be required. Match the wording to the actual electrical design.
