In reference to 334.15(C) what is meant by "angles"? If I install a 4/O SER on the face or the studs in a straight line across the studs is this code compliant?
I believe that normally 90^ & 270^ = Perpendicular, 0^ & 180^ = Parallel so these are not included in "angles". Any derivation from the above would be the angles that are being addressed.
