The Service and Installation Rules for New South Wales cover the requirements for the connection of electrical installations to the distribution network. The Rules are used by electricians and Accredited Service Providers.
The Service and Installation Rules for NSW Working Group, made up of industry stakeholders, has produced the November 2016 edition. This edition contains minor updates to the previous major update published in August 2016, which was to help facilitate the market-led rollout of smart meters in NSW.
There are two copies of the Rules below, one with the changes from the previous version underlined (for ease of recognition), and another unmarked version of the document.

Timing of implementation
The revised Rules included in the August 2016 version and included, with minor clarifying revisions, in this November 2016 version, should be implemented as soon as practicable with a staged transition period to allow the revised Rules to be promulgated and enable work in progress to be completed. The revised Rules may be applied now but in any case and as previously advised:
- All metering work is to comply with chapter 4 of the Rules after 30 September 2016 (it is expected that fuse derating to 80 amps can occur immediately), and,
- All work is to comply with the new Rules after 30 November 2016.
Summary of amendments in August 2016 Rules
The changes to the Rules are broadly summarised below, with an emphasis on Chapter 1 (General Requirements) and Chapter 4 (Service and Metering Equipment):
- The definitions are no longer individually numbered, (consistent with the format of other regulatory documents);
- Chapter 1 has been redesigned to bring more administrative items forward to the beginning of the chapter;
- The roles of Meter Providers and Distributors have been differentiated;
- Many individual items have been adjusted (e.g. the consistency of heights on poles for access by non-authorized persons, vegetation management around overhead services, etc);
- The definition of a connection point has been clarified (with associated diagrams), becoming the definition required by the Advanced Meters Act 2016. The Connection point, which is the point of delineation between the customer’s installation and a distribution network, has been more clearly explained.
- Substantial changes covering Service Protection Devices (SPD) and Meter Protection Devices (MPDs), including:
- The term "service fuse" has been replaced by SPD or Service Protection Fuse;
- Meter installations now require a MPD, usually an 80 Amp fuse (other protective devices may be used at the discretion of the Metering Provider), for each metered installation;
- Where an installation supplies only one metered customer, the SPD and MPD functions can be combined into one 80 Amp device. Generally it is expected that the existing service fuse would be relabelled appropriately and loaded with an 80 Amp cartridge.
- A changeover of physical devices in the conversion of metering from type 5 or 6 to type 4 does not constitute an alteration under the Rules. However, this exception does not exclude the installer from meeting the intent of the Rules in matters relating to safety including but not limited to Meter Protection Devices and fire rated mounting as required by the Rules.
Summary of minor amendments in November 2016 Rules
- Clause 4.7.2 and the Notes to Table 4.1 have been amended to clarify the protection requirements when a circuit breaker is used as a Meter Protection Device
