If an electrical panel is rated at 240/3/60 and your equipment draws 460/3/60, what is the correct action?

The scenario involves understanding the electrical ratings of the equipment and how they relate to the electrical panel's specifications. An electrical panel rated at 240/3/60 indicates that it can support three-phase current at a voltage of 240 volts and a frequency of 60 Hz. In contrast, the equipment that draws 460/3/60 requires three-phase power at 460 volts and also operates at a frequency of 60 Hz.

Connecting equipment directly without ensuring matching voltage ratings is unsafe and can lead to equipment damage, electrical fires, or other hazards. Therefore, the action of not connecting the equipment at that voltage is correct because doing so would subject the equipment to a voltage that is significantly lower than what it requires to function properly.

To power equipment rated at 460 volts from a 240-volt source, a different approach, such as using transformers, would be necessary to step up the voltage to a compatible level. However, without such a device in place, it is critical to avoid connecting the equipment directly, maintaining safety standards and operational integrity.
