This would be the same as air
compressor manufacturers who boast of 5 horsepower with a motor that
draws 7 amps. Impossible.

I remember seeing a "3HP" electric chain saw at Lowe's that plugs into a
standard (120V 15A) outlet.


After using the saw, clean up with the 5 HP shop vac. They use the
locked rotor rating that occurs for a half second or so before the
breaker trips. While meaningless by itself, if everyone uses the same
method it give you some idea for comparison.

I looked at my central A/C compressor, which lists locked rotor current
as 82A (240V). It normally uses 17A.
