New landfill gas generating site with a unit substation (15kV-480V) installed on a containment pad. There is grating from the top inside of dike wall to equipment pad. Edge of pad is extends 1'-6" from front and rear doors of 15kv gear. So as you approch the front and rear of the gear you are met with a 6" curb. Is this a violation of the NEC since there is not 3' of level working space at front and rear access doors?
Thanks for your input.

(A) Working Space. Working space for equipment operating at 600 volts, nominal, or less to ground and likely to require examination, adjustment, servicing, or maintenance while energized shall comply with the dimensions of 110.26(A)(1), (A)(2), and (A)(3) or as required or permitted elsewhere in this
Code.
(1) Depth of Working Space. The depth of the working space in the direction of live parts shall not be less than that specified in Table 110.26(A)(1) unless the requirements of 110.26(A)(1)(a), (A)(1)(b), or (A)(1)(c) are met. Distances shall be measured from the exposed live parts or from the enclosure or opening if the live parts are enclosed.
I would say that it does not comply with the work space and would be a trip factor.
