A new electrical room layout shows a casework run proposed beside a panelboard. What is the best coordination action before releasing the wall and casework layout?
Correct Answer
B) Reserve the required clear working space around the panelboard and keep it free of permanent obstructions
Panelboard locations must be coordinated so qualified workers have clear access for operation, inspection, and maintenance. The key construction-manager action is preserving electrical working space before walls and casework become fixed; the other choices confuse door swing or egress with equipment access, or defer a coordination problem until rework is likely.
Why This Is the Correct Answer
Panelboard locations must be coordinated so qualified workers have clear access for operation, inspection, and maintenance. The key construction-manager action is preserving electrical working space before walls and casework become fixed; the other choices confuse door swing or egress with equipment access, or defer a coordination problem until rework is likely.
Why the Other Options Are Wrong
Option A: The coordinator should approve the layout if the panel door can still swing open
A swinging cover does not prove a worker has clear space to stand, inspect, operate, and service the panel; door movement is only one small part of the access issue.
Option C: Let the electrical contractor shift the panel after finishes are complete if the casework blocks access
Waiting until finishes are complete turns a layout conflict into rework and may leave the panel trapped by permanent construction.
Option D: The coordinator should use the corridor egress width as the only access check
Corridor egress width is a life-safety path check; it does not replace the electrical equipment access space needed at the panel.
Memory Technique
Remember electrical equipment access coordination by its jobsite consequence: the correct move points to Reserve the required clear working space around the panelboard and keep it free of permanent obstructions.
