Bill Brooks should probably respond to this also, but reading the NEC, it looks like if the wires do not go inside the building to run more than 5 feet (as the crow flies), the the rapid disconnect does not apply. OR, less than 10 feet from the array IF the PV is mounted on that building.

The rapid shutdown language is so confusing. When looking at the rapid shutdown language, does PV systems "on" a building refer to only situations where the array is on a building; or does it include DC conductors as well. For example, if the DC conductors from a pole mounted array run up the side of a building before punching in to the inverter, does this require rapid shutdown? Is this PV system considered "on" a building? Aaron Aaron Mandelkorn Owner/Solar Specialist Renewable Energy Outfitters 719-221-5249 970-596-3744 www.reosolar.com reoso...@gmail.com
