The rapid shutdown as it currently stands is an array-level shutdown
and provides a zone outside of the designated area where the shock
potential has been mitigated. This means that the module interconnects
and PV source-circuits located behind roof-mounted modules do not
have to be controlled by rapid shutdown. Nor do the DC conductors
running to and from a roof-mounted junction box or combiner box
(both PV source and output circuit conductors) as long as they are
within 10 feet of the array. Conductors that enter a junction box behind
a roof-mounted array and then proceed into the building need to be
controlled within 5 feet of entering the building. Conductors between
a battery bank and an inverter or charge controller could conceivably
be less than 5 feet long, and thus not subject to being controlled under
690.12. The code outlines equipment performing rapid shutdown
be listed. In order for a product to be listed, a standard safety test
procedure must be in place for certifying the product. The current
standard safety test procedure is UL 1741.
