What is the minimum distance electrical panels must be from doors and windows?

The minimum distance that electrical panels must be from doors and windows is set at 36 inches. This requirement is in place to ensure safety and accessibility, allowing enough space for operation and maintenance of the panel without obstruction or risk of accidental contact.

By keeping a distance of 36 inches, it helps to avoid situations where a door or window might inadvertently obstruct access to the electrical panel, which could pose significant safety risks in emergency situations or during routine electrical work. The intent behind this regulation is to provide both an operational safety zone and a clear pathway to ensure that any circuit breaker can be accessed quickly and without hindrance.

Larger distances may be specified for certain applications or under specific codes, but the established minimum is consistent with safety guidelines aimed at preventing accidents and promoting ease of access for electrical emergencies.
