In which scenario would an air compressor require a dedicated circuit?

An air compressor requires a dedicated circuit if its power requirements exceed the capacities of standard outlets. This is crucial because using a standard outlet that cannot handle the compressor's load can lead to overloaded circuits, tripped breakers, or even electrical fires. Dedicated circuits ensure that the power supply is stable and adequate for the operational demands of the compressor, preventing interruptions and ensuring efficient performance.

While it is true that continuous use might suggest the need for a dedicated circuit, it is primarily the power requirements that dictate this need. Therefore, the emphasis is on ensuring the electrical system can handle the compressor's specific power draw without risk.
