For equipment rated 800 amperes or more, what is the maximum distance from the working space edge a door intended for egress can be located?

The correct answer indicates that for equipment rated at 800 amperes or more, a door intended for egress can be located a maximum of 25 feet from the edge of the working space. This requirement is in place to ensure safety and accessibility in high amperage environments, where the potential hazards are greater.

The 25-foot distance ensures that individuals can safely exit from the workspace without unnecessary delays, thereby reducing the risk of accidents or injuries in case of emergencies. It aligns with safety regulations aimed at facilitating quick evacuation from areas where electrical equipment is present, particularly when operating at such high current levels.

In contrast, shorter maximum distances would not provide sufficient exit options in larger areas or where equipment is spread out, potentially compromising safety. This regulation reflects a balanced approach to maintaining safety while taking operational considerations into account.
