Hi folks,
Probably a really easy question for most, but I am carrying out a 3 phase electric motor test on Monday on quite a large 'Brooke Crompton' motor from an AHU and just wanted to know if I have to remove the metal links (strappers) inside the terminal box of the motor?
Imagine a number 6 on a dice, I have each of the 3 phases on one side and then links which connect each phase to the other 3 terminals inside the terminal box.
I understand how to use my 'Megger' but wasn't sure if I touch one of my probes to each of the terminal pins (x6 if I remove the links) and the second probe to ground or one probe to each of the terminal pins (x3 if the links stay in) and the second probe to ground
Feed back appreciated
Apologies for very poor description, really hard to describe what I mean in words
