Incorrect Lugs Used - 07/23/05 03:29 AM

The attached photo is a hot joint on a 3phase motor isolator, the reason for the failure is that an incorrect lug (copper) was used to terminate an aluminium cable. As you can see in the photo the other two lugs under the tape are much larger, these are bi-metallic lugs.
