New South Wales Consolidated Regulations

ELECTRICITY SUPPLY (CORROSION PROTECTION) REGULATION 2008 - REG 4

4 Application of Regulation

(1) This Regulation does not apply to:

(a) a galvanic anode system that has been installed to protect:

(i) a compact structure, but only so long as the maximum current flowing through the system does not exceed 150 milliamperes, or

(ii) any other primary structure, but only so long as the maximum current flowing through the system does not exceed 150 milliamperes for each 500 metres of the length of the structure along its greatest dimension, or

(b) any corrosion protection system that has been installed to protect:

(i) the internal surface of a water storage tank, reservoir or other similar structure for storing water where the structure isolates the system current from the external environment, or

(ii) marine vessels that are not permanently moored.

(2) This Regulation applies to all other corrosion protection systems.

(3) In this clause:
"compact structure" means a structure (such as a storage tank) the greatest dimension of which, being a dimension of height, length or breadth, is no greater than 5 times the size of the smallest of those dimensions.
"galvanic anode system" means a corrosion protection system that operates by means of an electrochemical reaction in which a metallic anode corrodes.
