The following clearances are guidelines only. These are meant to compliment Rule 35.
RECOMMENDED CLEARANCES
The radial clearances shown below are only a guide for minimum clearances that should be established, when trimming, between the vegetation and the energized conductors and associated live parts whenever practicable.
A 
Radial clearances for any conductor of a line operating at 2,400 or more volts, but less than 72,000 volt 
4 feet 
B 
Radial clearances for any conductor of a line operating at 72,000 or more volts, but less than 110,000 volts 
6 feet 
C 
Radial clearances for any conductor of a line operating at 110,000 or more volts but less than 300,000 volts 
10 feet 
D 
Radial clearance for any conductor of a line operating at 300,000 or more volts 
15 feet

RECOMMENDED
CLEARANCES
The radial clearances shown below are only a guide for minimum
clearances that should be established, at time of trimming, between the vegetation
and the energized conductors and associated live parts where practicable. Reasonable
vegetation management practices may make it advantageous to obtain greater
clearances than those listed below:

Voltage of Lines 
Case 13 of Table 1 
Case 14 of Table 1 

Radial clearances for any conductor of a line operating at 2,400 or more volts, but less than 72,000 volt 
4 feet 
6.5 feet 

Radial clearances for any conductor of a line operating at 72,000 or more volts, but less than 110,000 volts 
6 feet 
10 feet 

Radial clearances for any conductor of a line operating at 110,000 or more volts but less than 300,000 volts 
10 feet 
20 feet 

Radial clearance for any conductor of a line operating at 300,000 or more volts 
15 feet 
20 feet
