Our delema: Changed a 3 phase motor to a 4 hp single phase. Bought a

Too late to call out an electrician for help.

Do 4 hp motors require a different switch? And/or does a 4 hp motor
require a different breaker. We have a 20 amp breaker.

Otherwise, I think we wired the switch wrong.

There is no LVC box on this saw. The wiring from breaker to socket
seems to be ok. When we plug the saw into the socket, the breaker
trips. The motor came wired, but not to the switch, since there was
no switch.

Any comments are welcome.

See if this helps:
