Does afdd work on a ring power supply?
Does AFDD work on a ring circuit? Yes, AFDD detects dangerous arc faults on toroidal circuits, spurs, radials and leads, regardless of connection method. However, if the ring circuit is broken, the ring becomes two radial circuits at the same potential. Power flows in both directions, no arcing.
