A disconnect is behind a locked electrical-room door, and authorized personnel carry the key. Which NEC term determines whether it can be reached quickly without climbing or removing obstacles?
- AWithin sight
- BConcealed
- CExternally operable
- Readily accessible
Why D is correct
Readily accessible addresses prompt access without climbing over or removing obstacles or using portable ladders. A controlled locked room may still qualify for authorized personnel when access itself remains prompt.
