Nec Working Clearances: 1001-2500 V
NEC (NFPA 70) working clearance distances — minimum clear distances in front of electrical equipment by voltage range and condition per NEC Table 110.26(A)(1) (0–600 V) and Table 110.34(A) (above 600 V)
| voltage range | condition 1 ft | condition 1 mm (mm) | condition 2 ft | condition 2 mm (mm) | condition 3 ft | condition 3 mm (mm) | nec section | standard |
|---|---|---|---|---|---|---|---|---|
| 1001-2500 V | 3 ft | 900 | 4 ft | 1,200 | 5 ft | 1,500 | 110.34(A) | NEC (NFPA 70) 2017 |
