Warning - More Than One Supply Labels - Safety Signs by Caledonia Signs

Alert personnel that the electrical equipment or system they are working on is fed by multiple power sources. This warning is crucial because isolating or switching off only one supply may not completely de-energize the equipment, leaving live circuits that pose serious risks of electric shock or equipment damage.

The primary reason to use these labels is to ensure safety during maintenance, repair, or inspection activities. Workers need to be fully aware that additional power sources exist, so they take extra precautions to identify and isolate all supplies before beginning work. This helps prevent accidents caused by unexpected live voltage and ensures compliance with safety regulations and lockout/tagout procedures.

These labels are typically placed on electrical panels, switchboards, distribution boards, machinery, or equipment where more than one electrical supply feeds into the system. Common environments include industrial plants, commercial buildings, renewable energy setups (such as solar arrays combined with mains power), and critical infrastructure where backup generators or alternative power feeds are present.

Using “Warning – More Than One Supply” labels promotes clear communication about complex electrical systems, reduces the risk of injury, and helps maintain operational safety standards. They are an essential part of a comprehensive electrical safety program, making sure that anyone working on or near electrical equipment fully understands the potential hazards involved.
