is sufficient with protective bushings on each end. Once you go to EMT, then
grounding bushings must be installed at both ends and the EGC needs to pick up
those bushings. More expensive and time consuming, but it looks better and you
can span a greater distance. <o:p></o:p></span></p>

years and the inspectors like the "bond" between the arrays.....<br>

color:#1F497D'>I’m looking for fresh ideas on how to run USE-2 wires between
subarrays on rooftops. Let’s say we have a flat roof commercial system with
dozens of separate rows of modules. How would you folks run the USE-2 wiring
between these arrays? We’ve been using J-boxes and EMT which is robust but time
consuming. I’ve also used strut with a cap strip on the top which effectively
makes a wire raceway but it is difficult to properly ground both ends of the
raceway and is also time consuming. </span><o:p></o:p></p>
