Scary Photo of the Month - August

We were called out to investigate a performance issue at a site, and were shocked to see this wire management. We suspect the AHJ made this contractor install physical protection after the strings were installed, which is why the contractor cut the PVC conduit in half, wrapped it around the wires, and zip-tied it back together. I don't know how this could have passed inspection...


However, the string wiring is still running unsecured on the roof. Ice and snow will lock up around the string wire and pull hard on the cables until something fails.



Even if you considered this adequate physical protection (of course its not), it's not going to last long when it's unsecured as shown by these photos here. In the rare instances where they used caddy blocks, they didn't even secure the conduit so of course they started to fall off!
