Hey guys just wanted opinions.....
I am adding a 3ph 63a switch fuse into the main DB in a warehouse.... now I tested phase rotation, and on the left handside of board I am getting L1/L2/L3.
on the right handside of the board I am getting L1/L3/L2! so I guess there has been a crosss within the bars behind somewhere.
I know previously they had problems with some 3ph motors, so they swapped phases at load ends. I believe I should install my equipment in the correct sequence as at the board (Br/Gy/Blk) to match L1/L3/L2 and mark up correctly at board. Do you guys agree with this? With regards good practise my head is telling me that I should resolve the problem at board and also at motor isolators too.
