The logs seem clean. In case it could help you, I have uploaded them here.

Debug Crash Log

Look above

Wires have a limit to how much power is allowed through them.

If you have a lot of lines all merging into one, that will overpower the line and it will burn out. On world load, this can happen via an "inrush current", where many connectors together briefly put a "burst" through the line that exceeds its limit.
Generally, you can not have more than 8 connectors merge into a single line.

It's basically impossible for me to see from these screenshots how many things you are combining into one wire, but that's my immediate guess on this matter.

Yes, you have centered the issue. The wires are connected to EnderIO energy storage that sometimes, in configuration mode, applies a high voltage to the wires, and I guess the wires burn out. Thanks for the explanation. I close the issue
