 (B) All sign installations shall maintain a clearance from adjacent power lines as follows:

Voltage—Line To Ground	H (ft.) Minimum Horizontal Clearance	V (ft.) Minimum Clearance Measured Either Diagonally or Vertically	V (ft.) Over or Under Catwalks Minimum Clearance Measured Either Diagonally or Vertically
Guy Wires and Neutrals	3	3	10.5
0—750 V Supply Cables Meeting Rule 230C2 and 230C3 NESC, 1997	3.5	3.5	11
0—750 V Open Conductors N.E.S.E. Rule 230C2 and 230C3	5.5	6	11.5
750V—22KV	7.5	8	13.5

 

Notes to table:

1.

Signs should never hang over any adjacent power circuits.

2.

Voltages are line to ground on a Y-Circuit with multi-ground neutral or between phases on an underground circuit.
