Australian Electrical Installations Standard AS 3000 states clause 2.3.2 defining the common requirements for CONTROL OF ELECTRICAL INSTALLATION. 2.3.2 Common requirements 2.3.2.1 General: Every circuit shall be capable of being isolated from each of the supply? conductors, in accordance with Clause 2.3.2.1.1 or 2.3.2.1.2 as? appropriate.? Provided that the service conditions allow and the appropriate safety? measures are maintained, a group of circuits may be isolated by a common? switch.? Provision shall be made to enable isolation of electrical equipment and to? prevent electrical equipment from being inadvertently energized. The? means of isolation shall be such that a deliberate action in addition to the? normal method of operation is required to energize the circuit.? NOTE: Such precautions may include one or more of the following measures:? (a) Provision for the fitting of a padlock.? (b) Warning tags or notices.? (c) Location within a lockable space or enclosure.? Short-circuiting and earthing may be used only as a supplementary measure.? Where an item of equipment or enclosure contains live parts connected to? more than one supply, a notice shall be placed in such a position that any? person gaining access to live parts will be warned of the need to isolate? those parts from the various supplies. Exception: A notice need not be provided where an interlocking arrangement is provided or the live parts are suitably shrouded to ensure that all the circuits concerned are isolated. Where relevant, suitable means shall be provided for the discharge of stored electrical energy.

Australian Electrical Installations Standard AS 3000 continues clause 2.3.2 defining the common requirements for CONTROL OF ELECTRICAL INSTALLATION. 2.3.2.1.1 Alternating current systems: Requirements for isolation of conductors in alternating current systems shall be as follows: (a) Active conductors: All active conductors of an a.c. circuit shall be capable of being isolated by a device for isolation. (b) Neutral conductor: (i) No switch or circuit-breaker shall be inserted in the neutral conductor— (A) of consumers mains; or (B) where the neutral conductor is used as a combined protective earthing and neutral (PEN) conductor for protective earthing of any portion of an electrical installation. NOTE: This requirement applies to situations such as an earth sheath return (ESR) system or a submain neutral used for earthing of an electrical installation in an outbuilding. (ii) A switch or circuit-breaker may operate in the neutral conductor of circuits other than those in Item (i) where— (A) the neutral pole of a multi-pole switch or circuit-breaker, having an appropriate short-circuit breaking and making capacity, is linked and arranged to switch substantially together with all active poles; or (B) the switch or circuit-breaker is linked with corresponding switches so that the neutral contact cannot remain open when the active contacts are closed. A switched neutral pole shall not open before and shall not close after the active pole(s). (iii) Where an item of switchgear is required to disconnect all live conductors of a circuit, it shall be of a type such that the neutral conductor cannot be disconnected or reconnected without the respective active conductors also being disconnected or reconnected. (iv) A switch in the control circuit of a fire pump shall operate in the neutral conductor. NOTE: No fuse shall be inserted in a neutral conductor. (c) Switching of earthing conductor prohibited An earthing conductor shall not be isolated or switched. A conductor used as a combined protective earthing and neutral (PEN) conductor shall not be isolated or switched.

If you are an electrical contractor looking for ways that you can attract and retain customers for the long-haul, I highly recommend taking a look at this webinar that Alan Manche and I presented for the National Electrical Contractor's Association last week: "Harnessing NFPA 70B and 70E for Customer Trust and Long-Term Success". In this webinar we talk about practical ways that you can leverage the requirements in NFPA 70B and NFPA 70E to become a "lifecycle provider" for your customers' electrical infrastructure. You will need a NECA account to view it:

One of the most read articles this year: https://lnkd.in/dqhjaSs3 This article from the experts at NICEIC aims to provide guidance for contractors when required to install a consumer unit and/or similar switchgear manufactured from a noncombustible material meeting the requirements of regulation 421.1.201, in a domestic installation forming part of a TT system earthing arrangement.

If you are considering upgrading your commercial electrical system, keep in mind that a full assessment of your current system must be performed first. Before making energy-saving modifications, your contractor must first consider the safety of the building’s existing electrical system and whether it will be able to accommodate those changes.
