For large equipment with a combined ampere rating of 1200 amperes or more, what is the minimum entrance width required for the working space?

The minimum entrance width required for the working space around large equipment with a combined ampere rating of 1200 amperes or more is established to ensure safety and accessibility for maintenance and emergency situations. According to standard electrical practices and codes, a width of 24 inches is necessary to provide sufficient access for personnel to operate safely and efficiently while working near high amperage equipment. This dimension allows for maneuvering tools and safely moving around the equipment, thereby enhancing the operational capacity of emergency responders as well.

Wider spaces, such as those greater than 24 inches, also support compliance with safety regulations by accommodating various situations that may arise during maintenance work or inspections. While adequate working space is critical for many levels of electrical equipment, the specific requirement of 24 inches for this voltage and current range aligns with established practices designed to protect both workers and equipment from inadvertent contact or mishaps.
