Standby Generator Electrical Panel Warning Label
When installing a standby generator with an automatic transfer switch (ATS), it is important, for safety reasons that main disconnect switches, load centers and/or distribution panels be identified with warning labels, indicating that the panels are fed from two independent locations. The utility and a standby generator.
A serviceman working on the electrical equipment in a home or business, may believe that by turning the main breaker to the "OFF" position that there will not be any electrical power on any device or appliance in the home or business.
The automatic transfer switch on sensing that there is no power past the main breaker will turn-on the standby generator and provide power to those devices and appliances that are connected.
Serious injury, including death could result.
Figure 1 shows a sample label that could be mounted on all electrical distribution boxes, load centers and disconnect switches.
You are welcome to print this page on label stock and adhere the label to the necessary equipment.
