I have a problem with a 3 phase knife switch the line side of line a is hotter than all hell while line b and c are cool they all pull the same amps yet the load side is also cool i replaced the wire of line A all wires pull 90 amps max they are all 3/0 copper i can't not find why 8 inches of the line side is hot coming into the knife switch and the fuse is hot i mean hot enough to almost burn oneself but the load side is not if anyone has any ideas please get back to me...at one point before i took the job the wire got so hot it burnt off the wire right at the enrty of the lug so i replaced the lug at the same time as the wire..now is it possible that if the blade was dirty and pitted this would have the same effect?
