New York State Master Electrician Practice Exam

Question: 1 / 400

For equipment rated 1200A or more, what is the required entrance width for working space?

18 inches

24 inches

For equipment that is rated 1200A or more, the National Electrical Code (NEC) specifies that the required working space must have a minimum width of 30 inches. This width ensures that electricians and technician personnel have enough room to safely access and work on the equipment. The requirement is intended to promote safety by minimizing the risk of contacting live parts and providing adequate space for the installation and maintenance of electrical equipment.

The confusion might arise from looking at other common working space requirements, such as those for lower amperage equipment or different conditions, which may have smaller width specifications. However, for high-capacity equipment like that rated at 1200A or more, adhering to the 30-inch width is essential to comply with electrical safety standards and ensure proper operation during maintenance activities.
