Answer:
Hi Alex,
Thanks for participating. There is not much information provided in the question. It appears that there is an enclosed switchgear, so the minimum depth of working space would be measured from the enclosure front. Based on the information provided, the minimum depth of working space required for switchgear supplied by a 4160 volts is 3 feet, with consideration of a phase to ground voltage of 2400. See NEC Section 110.34(A) and Table 110.34(A) for minimum working space depths for equipment over 1000 volts.
