3 What is IP rating IP Ingress protection (IP) classification A degree of protection in accordance with AS NOTE: Further information is provided in Appendix G.

6 Clause General Protection shall be provided against shock current arising from contact with parts that are live in normal service (direct contact) (basic protection) or parts that become live under fault conditions (indirect contact) (fault protection). Therefore, live parts shall not be accessible and accessible conductive parts shall not be live, neither under normal conditions nor under single fault conditions. Clauses 1.5.4, 1.5.5, and specify essential requirements regarding protection against electric shock including basic protection and fault protection. They also deal with the application of these requirements in relation to external influences, such as damp situations.

7 Protection by Barriers or enclosures (a) Degree of protection (i) (existing remains the same) (ii) (existing remains the same) (iii) Any IP rating shall suit the environmental conditions and the relevant mounting position as specified by the manufacturer. Eg. Weatherproof enclosure mounted vertically may be IP65 but horizontally has IP?? Eg. Cannot drill a hole in the bottom of an IP rated enclosure to let out condensation or water.

8 1.7.1 SELECTION AND INSTALLATION OF ELECTRICAL EQUIPMENT Electrical equipment, forming part of an electrical installation, shall be selected and installed to (a) (b) (c) operate in a safe and reliable manner in the course of normal operating conditions; selected and installed so as not to cause a danger from electric shock, fire, high temperature or physical injury in the event of reasonably expected conditions of abnormal operation, overload, fault or external influences that may apply in the electrical installation; and installed in accordance with the manufacturer's instructions.

9 1.7.2 (f) Installation work practice In order to address the essential requirement of Clause 1.7.1, electrical equipment shall be installed in accordance with safe and sound work practices including the following considerations: (a) to (e) existing, (i) Condensation issues. Installation of breathing or pressure equalization valve to assist in changes in humidity and drainage of moisture (j) Electrical equipment shall be installed to manufacturers instructions to ensure the marked IP rating is maintained Weep holes are not acceptable

10 4.1.1 Application The provisions of this Section form the minimum standard for the selection and installation of appliances, accessories and other electrical equipment not specifically covered in other Sections of Part 2 of this Standard that shall be achieved to satisfy Part 1 of this Standard Selection and installation Electrical equipment shall be selected and installed to perform the following functions, or to have the following features, associated with the proper design, correct construction and safe operation of the electrical installation: (a) (d) remain unchanged (e) Installed in accordance with the minimum requirements of this Section, and the additional requirements as specified in the manufacturer s instructions.

11 4.1.3 External influences (additional note and text at end of clause) NOTE: AS provides an IP classification and marking system for electrical equipment and enclosures that provide different degrees of protection against the entry of water and solid objects. NOTE 2: Purpose-made, anticondensation and water drains that maintain the IP rating of the enclosure may be used.

12 SCHNEIDER ELECTRIC Watertight condensationless valves

13 NOTE 3: Drilling a drain hole in the enclosure alone destroys the IP rating of the enclosure. Exemption: for meter enclosures may be rated at IP23 Electrical accessories located in the shaded area most have a degree of protection rated at IP33 or greater. Refer to Figures 4.1 and 4.2. The old unwritten rule of thumb of 45 degrees is not acceptable.
