G. Maintain 36” minimum clearance between barrier posts and the edge of the pad in front of the equipment doors so that they do not interfere with opening the doors.
And though this aspect is not covered by the NEC [90.1], good engineering requires consideration of what additional distance would improve efficiency for operation or maintenance.
The aisle (s) between pieces of such equipment, with live parts on both sides of the aisle, must be at least 4 feet wide. If the voltage exceeds 600, clearance must be increased even further.
Simply enter any desired location into the search function and you will get the shortest distance (air line) between the points, the route (route planner) as well as all important information.
NEC 110.26 defines a three-dimensional zone around equipment that must be kept clear. This zone is determined by specific measurements for depth, width, and height. Let''s break down each

Reference NESC Rule 234E for Diving platforms, water slide, or other pool A objects greater than 8 feet in height. Vertical clearance does not apply to neutral, comm, grounded guy, or TPX that are 10 feet
Electrical clearances are the minimum separation distances the National Electrical Code (NEC) requires between wiring, panels, overhead conductors, and everything around them. These
Minimum CLEARANCES in SECONDARY CIRCUITS are determined from Table 2M. The PEAK WORKING VOLTAGE for use in Table 2M is: 2.10.3.8, whichever is the higher value.
Visual guides can illustrate the necessary distances and help ensure that all employees are aware of the proper clearance specifications, thus promoting compliance and workplace safety.
Click Calculate Distance, and the tool will place a marker at each of the two addresses on the map along with a line between them. The distance between them will appear just above the map in both miles
