We have a situation where we have installed 2 runs of 3/c 500 MCM cable, direct buried, in parallel with each other. The cables were installed with approx 24" of separation except for 200 ft out of a 4000 ft run.
The AHJ approved the installation. The conversation is now centered around what derating, if any, should be applied for the 200 ft stretch of cables that are touching each other. There is no discussion of this in the NEC.
