Doubled-up NEMA pad connections?

[Whaleotter]

The utility I work for has multiple 13.8 kV ungrounded-Y 45MVAR shunt reactor installations that use a VCB for switching. The center phase Y connections on the VCBs have "doubled-up" 4-hole NEMA connections. The current flow is ~1900 Amps when the VCB is closed in. Recent IR surveys on several VCBs show slightly elevated temps on the center phase termination with Reactors switched in. I am looking for information on "doubled-up" NEMA pad terminations, whether this configuration is acceptable, and any information on ampacity ratings. See attached photo

It's acceptable if the temperature is within the wire and termination limits. Otherwise, run a 3rd jumper between the outside phase terminals.

I agree with Lionel.
Double up the other two and run jumpers from "A" to "C".
That will reduce the passing current on the center connection.
OR
It is what it is.
If the temps are not too high, just live with it.
