This is the same connection as we discussed above for single phase wiring expect that there are three phase wires instead of line and neutral.

. The three phase utility power as L 1 L 2 L 3 N are directly connected to the upper side of manual changeover switch while the backup power of three phase generator is connected to the first four right slots of at lower side. Confirm that all control contacts are closing. This is normally indicated by a humming sound when switch is closed.

Check connections with wiring diagram supplied with motor. Check to see that motor and drive turns freely. Check for loose wiring connections.

I P V. I P V x Cosθ. Open circuit in winding or control switch.

Check bearings and lubrication. Single phase motor starters are not commonly available since this is a rare case and with a little bit of know-how a 3-phase motor starter can easily be wired for single phase power. This is how Springer Controls does it in our UL508A certified panel shop weve also included a 3 phase motor contactor wiring diagram below.
