Multiple Supplies Warning Label

A Multiple Supplies Warning Label is used to alert technicians that an electrical installation may have more than one power source present. This electrical multiple supplies warning label clearly indicates that equipment may remain energised even when the main supply appears disconnected.

The label features a bold and highly visible warning:

WARNING – MULTIPLE SUPPLIES
Isolate all electrical supplies before carrying out work.

It also includes clearly marked write-in fields:

Isolate the mains supply at: ___________________
Isolate the alternative supplies at: ___________________

These dedicated fields allow responsible persons to specify exact isolation points, helping reduce the risk of electric shock, equipment damage, or serious injury.

Ideal for electrical panels, distribution boards, plant rooms, generator-backed systems, solar PV installations, battery storage systems, and any environment where dual or multiple electrical feeds exist.

Manufactured from durable, high-quality materials, this label is available in self-adhesive vinyl for quick application or rigid plastic for long-term fixed installation. The high-contrast yellow and black design ensures maximum visibility and compliance with standard safety sign conventions.
