[Andrew Truitt]

Davis - Cope makes covers for their Ladder cable tray system:

I am a fan.  Cable tray systems can be easier to work with than conduit for
long roof-top runs and decrease the likelihood of faults due to thermal
movement of the raceway.  There was a lively discussion around this topic
about a year ago, but I would be very interested to hear more wrenches'
viewpoints on the subject as cable tray usage in PV systems seems to be on
the rise.



For a brighter energy future,

"Don't get me wrong: I love nuclear energy! It's just that I prefer fusion
to fission. And it just so happens that there's an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it's wireless!"
