What width must access to working space be when equipment doors are opened simultaneously?

Access to working space around electrical equipment is crucial for both safety and efficiency when performing maintenance or inspections. According to the National Electrical Code (NEC), specifically in Article 110, the width of access must be sufficient to allow for the safe operation of the equipment, especially when doors or equipment may open simultaneously.

The requirement stipulates that the access must be at least 24 inches wide. This ensures that technicians or electricians have enough space to move comfortably without risking injury or damage to the equipment. A width of 24 inches strikes a balance between providing adequate access for tools, personnel, and safety while considering the physical constraints that may exist in some installations.

Wider access points, such as 30 or 36 inches, can be advantageous in certain situations, but the minimum requirement established by the NEC is 24 inches, reflecting the code's intent to maintain a safe working environment.
