Front clearance: There should be a minimum of 3 feet of clearance at the front of all electrical equipment, including panelboards, switches, breakers, starters, transformers, etc. Note that all panel doors and access doors must be able to open a minimum of 90 degrees. Side clearance: There should. In a case where equipment are installed facing each other, then distance “X” shall be considered the largest of clearances required by Table B1 (i. if “Equipment 1” has current and/or voltage ratings different than “Equipment 2” such that the required minimum clearance around each of them, based. Where access is required for regular maintenance or adjustment, the relevant devices shall be located between 0,4 m and 2,0 m above the servicing level. It is recommended that terminals be at least 0,2 m above the servicing level and be so placed that conductors and cables can be easily connected. That means 3 ft deep, 30 in wide, 6½ ft high—right in front of the disconnect itself, not just the condenser. As voltage increases, so do the clearance requirements. Once you get into commercial or. The Width of working space is defined in 110.
