Hi guy's
I am in desperate need of some logic to my problem.

We are using 95mm Wesbraid soft jumpers, from the one panel jumping across the room to another panel VIA a open cable tray, the jumpers are about 6 metres long, we have two of these jumpers in parallel for each phase.

Now for my problem.
The RED PHASE each jumper is carrying 250 Amps.
The WHITE PHASE each jumper is carrying 250 Amps.
The BLUE PHASE NOW THERE'S MY ISSUE,
The one jumper is carrying 500 Amps.
The other jumper is carrying sometimes 1 Amp,
Sometimes 5 Amp and sometimes 125 Amp,
Never more than that.

We looked and the lug to see for over heating and NO the insulation tape still intact.
We followed the jumper mm by mm to for burning and still intact.

The jumpers are same length.

Unfortunately the is a hospital and it's on the ESSENTIAL supply we have taken infrared scans and it is alarming we have on that STUBBY over 110 degrees.

We are making plans with new jumpers to replace the overheated one and the one that's giving us this issue.

IF ANYBODY OUT THAT MIGHT AN EXPLANATION IT WOULD BE GREAT.

THANKS
FRENCHIE
