Warning Triple Supply Label

This Warning Triple Supply label alerts electricians, service technicians and emergency personnel that an electrical installation can be energised from three separate sources. It is intended for complex systems where assuming a single supply could create a serious isolation risk.

Multi-source electrical installations

Typical applications include sites combining grid supply with solar PV, battery energy storage, generators or other alternative supplies. The label provides an immediate warning that more than one isolation action may be necessary before equipment is considered de-energised.

Prominent warning identification

Position the label where personnel are likely to begin isolation or access electrical equipment, such as at relevant switchboards or distribution equipment. The exact three sources and isolation points should be identifiable elsewhere in the installation documentation and labelling.

Do not rely on the warning alone

This label communicates the presence of triple supply but does not define a complete isolation sequence. Personnel should follow the site-specific shutdown procedure, system drawings and electrical safety practices applicable to the installation.
