[RE-wrenches] AFCI disturbances.

[William Miller]

Steve:

The PV is 200 feet away on the other side of a building. We have THWN in PVC conduit. This job was installed over 10 years ago. We don't want to repull all of the leads for 6 strings in PV wire. 

We Void splices like the plague but the PV leads terminated in a HU361 switch and we needed to splice on some short leads to make this work. 

Are you telling me we can no longer use 600 volt rated building wire and/or standard 600 volt rated wire nuts on PV circuits with your products?  If so, this is a BIG deal for installers. 

Thanks,

William
