I couldnt find an exact answer through search.

As I understand it, the rapid shutdown device can be eliminated by placing the central inverter within 10 feet of an array. To me this means 10 feet radial. This makes sense to me (since firefighters are not going to sit there with a tape to get exact numbers) but I seem to find another interpretation on a few websites which think that the 10 feet is the length of conduit or DC wire from the array (thus not a radial distance). Anyone have any experience dealing with this? Which one is right?

Another question, what happens when there are two arrays on my roof? One on one side of a roof and one on a the little roof above my garage? To me, the 10 foot rule still means 10 feet from AN (either or) array. But one site suggests that it is 10 feet from BOTH arrays which is harder to comply with even with rapid shutdown devices.

Thanks in advance.
