What is the minimum required working space in front of an electrical panel in a dwelling?

1. 24"w x 36"d

2. 30"w x 36"d

3. 36"w x 30"d

4. 48"w x 24"d

The correct answer is: 30"w x 36"d

The correct minimum required working space in front of an electrical panel in a dwelling is indeed 30 inches wide by 36 inches deep. This requirement is established to ensure that there is sufficient room for a technician or homeowner to safely access the electrical panel while conducting maintenance or repair work. The specified dimensions provide the necessary clearance to allow for the opening of the panel doors and for a person to safely operate within that space without obstruction, which can help prevent accidents and injuries when working with electrical systems. Proper working space is critical in maintaining safety standards, as it promotes an organized and efficient environment for electrical work. While other options may suggest different dimensions, only the 30 inches by 36 inches measurement meets the established guidelines for safety and functionality in working around electrical panels.
