What is the MINIMUM required width of clear working space in front of a service panel or motor control center rated 600 volts or less?
a.24 inches
b.30 inches or the width of the equipment, whichever is greater
c.18 inches
d.48 inches in all cases
Explanation
The working space in front of electrical equipment must be at least 30 inches wide, or the width of the equipment if that is greater, so a worker can operate and service it safely. 24 and 18 inches are too narrow, and 48 inches is more than the general minimum required.
