Rule 84.8-D1

84.8-D1)    Above Or Below Supply Line Conductors: (See Rule 32.2-F.)

a)    Crossings in Spans: Service drops which cross below supply line conductors of 0-750 volts, or above supply line cables where treated as in Rule 57.8, may have a vertical clearance less than as specified in Table 2, Case 4; Column C (48 inches), from such supply conductors, but not less than 24 inch; provided the crossing is 6 feet or more from any pole which sup- ports any conductor involved in the crossing but which does not support both conductors involved in the crossing.

b)    Supported on the Same Pole: Service drops which are supported on a pole which also supports supply conductors and which are not on a pole-top clearance attachment may have a vertical clearance less than as specified in Table 2, Case 9, Column C (48 inch), above or below supply line conductors provided not less than the clearance shown in Table 15 are maintained.

Rule 84.8-D1

84.8-D1)    Above Or Below Supply Line Conductors: (See Rule 32.2-F.)

a)    Crossings in Spans: (Table 2, Case 4, Column C [48 inches]): Service drops which cross below supply line conductors of 0-750 volts, or above supply line cables where treated as in Rule 57.8, may have a vertical clearance less than as specified in Table 2, Case 4; Column C (48 inches), from such supply conductors, but not less than 24 inch; provided the crossing is 6 feet or more from any pole which sup- ports any conductor involved in the crossing but which does not support both conductors involved in the crossing.  Vertical Clearances may be reduced to not less than 24 inches provided:

1)    Crossings are below line conductors of 0-750 volts, or above line cables as in Rule 57.8, and

2)    Crossing is 6 feet or more from any pole supporting one, but not both, involved conductors.

b)    Supported on the Same Pole: (Table 2, Case 9, Column C [48 inches]):  Service drops which are supported on a pole which also supports supply conductors and which are not on a pole-top clearance attachment may have a vertical clearance less than as specified in Table 2, Case 9, Column C (48 inch), above or below supply line conductors provided not less than the clearance shown in Table 15 are maintained.  Vertical clearance may be reduced to not less than the values shown in Table 15 , provided pole–top clearance attachments are not involved.
