🔍 Key Concepts

• air compressor unloading mechanism during startup • effect of starting under full load on electric motors and circuit protection • relationship between system pressure, compressor speed, and load

💭 Think About

• Think about what the unloader does for a compressor right when it starts: does it increase or decrease the starting load on the motor? • If the compressor starts while fully loaded, which part of the electrical system will react first to protect the motor? • Which option describes something that would most likely happen immediately at startup, rather than slowly over time?

✅ Before You Answer

• Be clear on the function of the unloader (to reduce starting load/pressure on the compressor). • Consider how an electric motor behaves if required to start under excessive mechanical load. • Ask which choice involves a protective device that responds to high starting current.
