How many meters away is the level 3 electrical distribution box from the machinery

The minimum working clearance in front of a level 3 electrical distribution box depends on voltage and condition, typically ranging from 4 to 5 feet for 151–1000 V systems under Condition 3.Working Clearance RequirementsAccording to NEC 110.26, the depth of working space in front of electrical equipment is measured from the enclosure front, not the live parts, and varies based on voltage-to-ground and the condition of opposing surfaces:Condition 1: Exposed live parts on one side, no live or grounded parts on the other.Condition 2: Exposed live parts on one side, grounded parts on the other.Condition 3: Exposed live parts on both sides. For a 151–600 V system, Condition 3 requires a minimum depth of 1.2 meters (4 feet), while for 601–1000 V, Condition 3 requires 1.5 meters (5 feet) from the front of the distribution box to any obstruction, including machines (ExpertCE, Mike Holt) .Width and Height ConsiderationsWidth: Must be at least 762 mm (30 inches) or the width of the equipment, whichever is greater, to allow full access and door operation to 90 degrees.Height: Minimum headroom of 2.0 meters (6 ft 6 in) from floor to ceiling or overhead obstruction is required.Practical ImplicationsEnsure the machine is positioned outside the required working space to allow safe inspection, maintenance, and emergency egress.The working space must remain clear of storage, tools, or other obstructions.If the machine or other equipment is across an aisle, Condition 2 may apply, allowing slightly reduced clearance if only qualified personnel access the area simultaneously. By following these NEC guidelines, you ensure safe operation and maintenance of the level 3 electrical distribution box while maintaining compliance with electrical safety standards (ECM Web, Electrical License Renewal) .
