Having to re do my Level 3 after doing the job for bloody years.
Got a question im stuck with, if anyone could help would be great.
A motor is reconnected into a circuit and switched but runs the wrong way , how will you correct this malfunction and how could it have been prevented form happening????

Thanks.

Simple one, When the motor was re-connected the phases were connected in the wrong order, to fix it swap 2 of the phases over in the isolator (load side).

To prevent, label conductors when they were disconnected or use a phase sequence meter when re-connecting to observe correct sequence.

Thanks Ohm, much appreciated. On back to back lived in rewires and not got a minute. Cheers.
