Table 1 figures—

1Figures (a) and (b) will assist in understanding the required minimum safety clearance for aerial lines constructed to operate at a voltage of more than 66kV.

2Figure (c) will assist in understanding the required minimum safety clearance for aerial lines constructed to operate at a voltage of 66kV or less (that is, minimum safety clearance from nearest conductor (maximum swing and sag)).

(a)

(b)

(c)

Vertical dimension (A) applies for example to:

· Balconies
· Terraces
· Walkways
· Bridges
· Scaffolds

Vertical dimension (B) applies in relation to things such as:

· Roofs with a slope of less than 45°
· Parapets wider than 0.1 metre
· Pergolas
· Carports

Horizontal dimension (C) applies to the same as (A) and (B)

Horizontal dimension (D) applies in relation to things such as:

· Roofs with a slope of 45° or more
· Flag Poles
· Light Poles

Note—

As required by section 10AA(2) of the Subordinate Legislation Act 1978, the Minister has certified that, in the Minister's opinion, it is necessary or appropriate that these regulations come into operation as set out in these regulations.
