Hi all,
So we are designing a commercial parking structure PV array. I am working on sourcing cable tray but have a few nagging questions I can't seem to find anywhere so was hoping someone here could help.
From what I understand, all the literature seems to say that the "tray" will not be filled past the 50% capacity of it's area (Other literature recommends no more than 40%).
So, If using 1000V PV wire @ 0.261 O.D. x 42 conductors (most in any one length of tray) = 10.962 in
Which means I would need a tray with at least TWICE that fill capacity correct?
That sucks because instead of the 6"W x 2"D tray I was looking at with a fill capacity of 12.09 in. I will need to use the 12"W x 2"D tray with a fill capacity of 24.18 in. unless there is something I am missing.
Does this sound right to you guys?
Thanks in advance.
