All, I'm just starting a 500kwh LFP battery system that requires a max. distance of 40' from each battery cabinet to the DC combiner.
I am considering using a cable tray instead of an enclosed wireway for this. The battery cable used is ALL-Flex CT multi-rated MTW / THHW, and will be greater than or equal to 1/0, per NEC 392. I haven't read up a lot yet on it but I assume cable tray allows single conductor ampacity to be sized as in free air per 310.17, with perhaps some caveats. Have any of you used cable tray in a similar fashion? Pointers? Thanks. -- *Kirk Herander / **kirkh@vermont.solar <kirkh@vermont.solar>* *Owner|Principal, VT Solar, LLC* *Celebrating our 32st Anniversary 1991-2023!!* dba Vermont Solar Engineering 802.863.1202
