First post

Hello all, I'm here because I'm at my whits end. I have a wolf 8kv deisel generator that is linked to an ATS for the house. All works fine manually but I need to extend the comms cable that came with the ATS. I can't seem to find the 6 core cable needed & the closest I can get is to have it made.

Marks on cable are Zr-rvv 300/300v
