What is the minimum clear space required for an electrical service panel?

The minimum clear space required for an electrical service panel is specified to ensure safe and adequate access for maintenance and emergency situations. The correct dimensions of 30 inches wide by 78 inches high by 36 inches deep provide sufficient room to work on or around the panel without obstruction. These dimensions help to prevent accidents by ensuring that an electrician can safely access the panel and perform necessary tasks, such as disconnecting the service or addressing any issues.

The width allows for proper clearance on either side of the panel, the height ensures accessibility without interference from overhead structures, and the depth permits room for tools or equipment that may be needed during service. Adhering to these minimum requirements is crucial for compliance with electrical codes and safe practice standards in the field.
