Determining Working Clearances | ECM

Th of Working Space Sec. 110.26Condition 1, Table 110-26Condition 2, Table 110-26Condition 3, Table 110-26Width of Working Space Sec. 110-26Ght of Working Space Sec. 110.26SummaryWorkspace OriginsThe depth of the working space in front of exposed live parts must be at least as great as the distances outlined in Table 110-26(a). You must measure distances from live parts or from the front of the enclosure or opening in which the live parts are enclosed. The working clearance in front of the equipment on which you're working is also dependent on the composition of the facing wall and whether it houses live electrical parts. As you'll note in the Table, there are three conditions noted for two voltage levels 150V or less and 151V to 600V-to-ground. For example, the clearances of a 120V/208V, 3-phase, 4-wire system fall under the 150V-to-ground or less category while a 277V/480V, 3-phase, 4-wire system falls in the 151V- to 600V-to-ground classification. The text below Table 110-26(a) explains the application and use of all three conditions.Get price
