2) What are the names of the electrical terminals on a typical compressor?
What does each terminal do?
SM: Common, start, and run. Common acts as a neutral, though on 220 volt
comps, the common terminal is "hot"

No..there is NO NEUTRAL on a 220VAC compressor...not single, or 3 phase..you
are wrong.

. Start provides for extra torque for
starting. On refrigeration compressors, the start terminal is usually only
powered for a second or two, via a start relay. On AC units, it is often
hooked to a motor run capacitor. Run terminal provides the power to run
the
compressor.



What ASHRAE site you try to steal that from?

SM: During startup (of start relay units) power is supplied to the
S
terminal, and exits through the C terminal. After the compressor
motor
starts, power is then supplied to R terminal,a nd exits through the
C
terminal.
