Answer 1

The required working space around electrical equipment operating at 1000 volts or less, which may need servicing while energized, must be the width of the enclosure or a minimum of 30 inches, whichever is greater.

Step-by-step explanation:

The question pertains to the required working space around electrical equipment that is likely to be serviced while energized and operates at 1000 volts nominal or less to ground. According to the National Electrical Code (NEC), if such equipment is located in a space with limited access, the width of the working space must be the width of the equipment enclosure or a minimum of 30 inches, whichever is greater. This requirement ensures safety and accessibility for personnel examining, adjusting, servicing, or maintaining the equipment while it is energized.
