Millwork shown on the latest drawing occupies the required space in front of a panel. What needs resolution before the price is finalized?
- AInstall a larger main breaker
- BMount the panel behind the shelving
- Revise the layout to preserve required working space and access
- DTreat movable shelf doors as working clearance for the described C-10 installation and documented operating conditions
Why C is correct
The best answer is: Revise the layout to preserve required working space and access. Electrical working space must remain clear for operation and maintenance. Shelving obstructs access, and changing the breaker rating has no relationship to the physical safety requirement. 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.
