Voltage | Minimum Separation Distance |
Less than 300 volts (insulated lines) | 3 feet (0.9 m) |
Less than 300 volts (uninsulated lines) | 10 feet (3.1 m) |
300 volts to 50 kv | 10 feet (3.1 m) |
| 10 feet (3.1 m) + 0.4 inches (1.0 cm) for each 1 kv over 50 kv |
More than 50 kv | Note: You may use an alternative minimum separation distance of 2 times the length of the line insulator, but never less than 10 feet (3.1 m). |
EXEMPTION: | Scaffolds and conductive materials handled on scaffolds may be closer to power lines than the minimum separation distance specified in Table 2 if all of the following are met: |
| 1. Less clearance is necessary to do the work; |
| 2. The utility company or electrical system operator has been notified of the need to work closer to the power lines; |
| 3. The utility company or electrical system operator has done at least one of the following: |
| a. De-energized the lines; |
| b. Relocated the lines to meet the minimum separation distance requirement; |
| c. Installed protective coverings over the lines to prevent accidental contact. |
