Main Isolator – Normal Supply Label

This label identifies the main isolator controlling the normal electrical supply. It is particularly useful on installations that also include generator, emergency, battery or stand-alone supplies and therefore require each source to be clearly differentiated.

Typical applications

Suitable for switchboards, backup-power systems, generator installations, commercial electrical systems and sites with multiple main switches.

Clear normal-supply identification

Position the label directly adjacent to the relevant isolator. Using the term “Normal Supply” helps personnel distinguish the everyday source from alternative or emergency supplies during maintenance, switching and fault-finding.

Coordinate with the complete label set

Use consistent terminology across generator, emergency, grid and battery supplies. Confirm the label wording against the electrical drawings and installed switchboard arrangement before fitting.
