An indoor battery system is added beside occupied space. Which listing, disconnecting, and fire-safety items belong in coordination?
- AOnly wall color
- BOnly battery voltage for the described C-10 installation and documented operating conditions
- COnly utility rate
- Required listing, disconnects, and fire controls
Why D is correct
The best answer is: Required listing, disconnects, and fire controls. Energy storage introduces stored fault energy, fire, chemical, access, shutdown, and environmental issues. The complete listed system and applicable building and fire requirements control. This transferred field condition tests the same installation or safety principle in a different project context. The other choices conflict with the cited rule, listing, safe-work process, or necessary diagnostic sequence.
