How much clearance is required in front of an electrical panel?
Panels need clear working space at least 36 in deep, 30 in wide (or the equipment width), and 6½ ft high (IRC E3405.2).
The IRC requires clear working space in front of panelboards and other energized equipment likely to need servicing: at least 36 inches (914 mm) deep measured from the live parts, and at least 30 inches (762 mm) wide — or the width of the equipment, whichever is greater.
That space must be clear from the floor to a height of 6½ feet (78 inches / 1981 mm) or the top of the equipment, whichever is greater, and must allow equipment doors or hinged panels to open at least 90 degrees. Don't store anything or run foreign piping and ducts through it.
