How much clearance do you need around an electrical panel?
The Occupational Safety and Health Administration (OSHA) and the National Electrical Code (NEC), require that electrical panels have a minimum of 3 feet (36 inches) of clearance and a minimum headroom of 6.5 feet or the height of the equipment whichever is greater.
What is the minimum clearance requirement to maintain sufficient access working space around equipment?
110.32 Work Space About Equipment.
Where energized parts are exposed, the minimum clear work space shall be not less than 2.0 m (6 ½ ft) high (measured vertically from the floor or platform) and the width of the equipment or 914 mm (3 ft) wide (measured parallel to the equipment), whichever is greater.
Can you put something in front of electrical panel?
For equipment serving between 120 volts and 250 volts, the regulations require a mini- mum of three feet of clearance. The width of the working space in front shall be 30 inches minimum or width of the equipment. The OSHA standard (29 CFR1910. 305 (d)) requires a dead front on electrical panel boards.
Can I build a closet around my electrical panel?
The short, safest and most efficient answer to this question is yes. According to the national code, with relation to electrical panels in closets: NEC 240.24D Overcurrent devices shall not be located in the vicinity of easily ignitable materials, such as a clothes closet.
What is NEC clearance?
110-26 of the National Electrical Code (NEC): 1) at least a 3-ft clearance in front of all electrical equipment; 2) a 30 in. -wide working space in front of equipment operating at 600V or less; and 3) minimum headroom clearance of 6 ft or the height of the equipment, whichever is greater.
What is the requirement of working area around the electrical equipment?
To be on the safe side, the working space and space around electrical equipment should always be clear per 110.26(A), if possible. As a basic rule, there should be at least 3 feet of space in front of all equipment with a 30 inch width as well as 6½ feet of headroom space.
What is electrical clearance?
The electrical clearance is the electrical isolation between two conductive components, whereas the creepage indicates the conduction of electricity across the surface of a nonconductive component. The clearance and creepage distance are two important parameters while designing an electrical assembly.
What is the minimum required height of the working space?
Like the dimension for width of working space, there is a minimum dimension for working space height. If the height of the electrical equipment is 61/2 feet or less, the minimum height shall be 61/2 feet. For example, the height of a panelboard installed on a concrete block wall is 5 feet, 10 inches.
What is the minimum working space height?
In all cases, the work space shall permit at least a 90 degree opening of equipment doors or hinged panels. 3. Height of Working Space. The workspace shall be clear and extend from the grade, floor, or platform to a height of 2m (6½ ft.) or the height of the equipment whichever is greater.
