Planned Live Low Voltage Work SWMS
Planned diagnostic, testing, and proving-dead work on energised LV equipment under a formal Live Work Policy, permit, and risk assessment.
SWMS variants reference your state's WHS legislation. Instant download after payment.
Planned live low voltage electrical work covers diagnostic measurement, proving-dead verification, and authorised testing on energised installations where de-energisation is not reasonably practicable. The work is permit-controlled under a formal Live Work Policy and is High-Risk Construction Work under WHS Regulation s. 291 — the duty holder must prepare a SWMS before work commences and keep it available throughout. This SWMS template covers the planned-intervention pathway: scheduled diagnostic work, supply-side voltage and current measurement at energised terminals, fault clearance verification, and any task where the upstream isolation point cannot be made dead within the planned outage window. The reactive fault-finding pathway is governed by the separate Electrical Fault Finding SWMS — workers should isolate first under that SWMS where possible and only escalate to live work under this template when de-energisation is not reasonably practicable. Australian electrical contractors must follow AS/NZS 4836:2023 (Safe working on or near low-voltage electrical installations and equipment) and the Managing Electrical Risks in the Workplace Code of Practice. The Wiring Rules AS/NZS 3000:2018 (with Amendments 1–3 and Ruling 1) govern the underlying installation. State Electrical Safety Acts impose additional licensing and authorisation conditions on live workers — these vary materially between jurisdictions.
Hazards identified
10 hazards covered, sorted by priority.
Fatal — cardiac arrest, deep burns. Single most common cause of electrical worker fatalities in Australia.
Severe burns, permanent vision loss, hearing damage, blast injury. Can occur with no direct contact.
Lung injury, ruptured eardrums, ejection injuries from flying components.
Electric shock during apparently safe work. Particularly significant in cable trays carrying multiple circuits.
Worker proceeds with bare-hand work on what they believe to be a dead conductor. Fatal outcome.
Heat exhaustion, impaired judgement, dehydration. Increases secondary error risk.
Delayed rescue from electric shock can convert a recoverable injury into a fatality. Cardiac arrest window is minutes.
Compounded injury — electric shock followed by fall from working position. Can be fatal even from low heights.
Arc flash and burns to worker. Common with non-insulated tools or tools modified to fit confined spaces.
Worker proceeds with live work where de-energisation was reasonably practicable. Erodes the safety-justification baseline of the Live Work Policy.
Control measures
Hierarchy-of-controls order: elimination → substitution → isolation → engineering → administrative → PPE.
- 1Eliminate live work where reasonably practicable — the default position is isolation. Live work proceeds only under the documented Live Work Policy with written justification per WHS Reg s. 19 'reasonably practicable' test.
- 2Permit-to-Work issued by an authorised person before work commences. The permit identifies the specific equipment, scope of energised contact, duration, and personnel authorised on-site.
- 3Risk assessment per AS/NZS 4836:2023 — covering arc flash incident energy calculation, PPE category selection, and exclusion zone establishment.
- 4Test-before-touch on every conductor using a proven voltage tester. Test the tester on a known live source immediately before and immediately after the proving-dead measurement (the 'three-step test').
- 5Insulated tools rated to 1000 V minimum, in current calibration, with no visible damage to the insulation barrier.
- 6Arc-rated PPE selected to meet the calculated incident energy at the working distance — minimum Category 2 (8 cal/cm²) for typical LV switchboard work. Includes arc-rated coverall, hood with face shield, gloves with leather over-gloves, and dielectric footwear.
- 7Exclusion zones marked and barricaded per state Electrical Safety Regulations. No unauthorised personnel within the No Go Zone for the conductor voltage class.
- 8Authorised second person on site — competent in low-voltage rescue and CPR, equipped with an insulated rescue hook, with line-of-sight or audio contact maintained throughout.
- 9Emergency response plan rehearsed before work commences — including isolation point location, defibrillator location, and the immediate procedure for low-voltage rescue using an insulated rescue hook.
- 10Pre-start brief covering the specific scope, identified hazards, exclusion zones, emergency response, and the conditions that would terminate the live work (changed conditions, equipment fault, worker fatigue).
- 11Stop-work authority — any worker may halt the live work without consequence if conditions change or if they assess the residual risk as unacceptable.
- 12Heat-stress monitoring — rotation of personnel out of arc-rated PPE on a documented cycle when ambient temperature exceeds 30 °C, with hydration breaks built into the work schedule.
- 13Tool tethering for any tools used at height to prevent dropped-object incidents triggering falls or secondary faults below.
- 14Post-work inspection of test instruments, PPE, and the equipment worked on — record any damage or discrepancy in the permit and isolate from service if the integrity of any item is in question.
Applicable Codes of Practice
Becomes legally binding under Section 26A of the WHS Act from 1 July 2026. PCBUs must either comply with this Code or demonstrate that their alternative approach achieves an equivalent or higher standard of health and safety. SafeWork NSW inspectors can issue improvement notices specifically for non-compliance. The Code's Part 4 covers safe systems of work for electrical work and explicitly addresses live LV work conditions.
Australian/New Zealand Standard governing the practice of safe working on energised LV equipment. Defines test-before-touch, exclusion zones, PPE categories, permit requirements, and the role of the safety observer. Cited explicitly in the Managing Electrical Risks Code as the primary practice standard for this work.
Current consolidated set with Amendments 1 (January 2020), 2 (April 2021), 3 (May 2023), and Ruling 1 (May 2024). Governs the installation being worked on; relevant when live work is required to verify continuity, polarity, or earth-fault-loop impedance on installations being commissioned.
Becomes legally binding under Section 26A of the WHS Act from 1 July 2026. Establishes the hierarchy of controls used throughout this SWMS — elimination (de-energisation) is the primary control, with substitution, engineering, administrative, and PPE controls applied where elimination is not reasonably practicable.
Becomes legally binding under Section 26A of the WHS Act from 1 July 2026. Sets out the SWMS preparation requirements for High-Risk Construction Work under WHS Reg s. 291 and the principal contractor's WHS management plan obligations under WHS Reg s. 309.
High-Risk Construction Work triggered
Planned live LV work involves direct measurement, testing, and proving-dead on energised conductors. The work falls within the High-Risk Construction Work definition under WHS Regulation s. 291 because the worker is in physical proximity to energised conductors during the planned task — the trigger applies regardless of voltage class above 50 V AC.
Failure to prepare a SWMS before High-Risk Construction Work commences is a contravention of WHS Regulation s. 291. Category 2 offences under WHS Act s. 32 — where a duty breach exposes a person to a risk of death or serious injury without proof of recklessness — attract substantial monetary penalties for body corporates and individual duty holders; refer to the current SafeWork NSW penalty schedule for the NSW-indexed 2025–26 figures. Category 1 reckless-conduct offences under WHS Act s. 31 attract up to approximately $10.42 million for a body corporate, $2.17 million for an individual PCBU or officer, and $1.04 million for an individual worker, with up to 10 years' imprisonment (NSW-indexed at 1 July 2025). VIC maximum penalties under the Occupational Health and Safety Act 2004 differ in structure and amount and are set at VIC variant-generation time.

Worked example
A licensed electrical contractor in Sydney is engaged to commission a 400 A main switchboard on a five-storey commercial fit-out in Parramatta. The principal contractor's outage window is limited to the weekend, but the building owner requires power maintained to existing tenant equipment in the basement throughout. The electrician must measure phase rotation and verify the polarity of three new tenant feeders at the energised LV bus. The job value is $4,200 for two days of commissioning. Before live work commences, the electrician's supervisor reviews the company Live Work Policy, confirms that de-energising the main switchboard is not reasonably practicable due to the building owner's tenant supply requirement, and issues a permit-to-work specifying the scope (three-feeder polarity check, two-hour duration, two authorised workers). The worker dons Category 2 arc-rated PPE, conducts a test-before-touch on each conductor with a proven voltage tester, completes the polarity check using insulated probes, and signs the permit closed. A safety observer maintains line-of-sight throughout with an insulated rescue hook within reach. Total live exposure time is under 15 minutes; the remaining commissioning work proceeds de-energised under the company's Electrical Isolation & LOTO SWMS.

Frequently asked questions
When is live LV work allowed in Australia?
Live LV work is permitted only when de-energisation is not reasonably practicable. The 'reasonably practicable' test under WHS Act s. 18 considers the likelihood and severity of the risk, what the duty holder knows about it, the availability of suitable controls, and the cost of those controls. A documented Live Work Policy is the standard mechanism for justifying when live work proceeds — without it, an inspector may treat the live decision as a Category 2 breach. This SWMS sits inside that policy framework, not above it.
Does this SWMS replace my company's Live Work Policy?
No. The Live Work Policy is the company-level document that authorises live work in principle, defines who can issue permits, and sets the conditions under which live work can be considered. This SWMS is the task-level document for the specific job — it records the hazards, controls, exclusion zones, and worker acknowledgements for a particular instance of planned live work. Both documents must exist; one does not replace the other.
What's the difference between this SWMS and the Electrical Fault Finding SWMS?
Different intent. This SWMS covers planned, scheduled live work — diagnostic measurements or proving-dead where the outage cannot be taken. The Electrical Fault Finding SWMS covers reactive work — investigating a known or suspected fault, with the default expectation that the worker isolates before investigating. Use this SWMS for planned interventions on energised equipment; use Fault Finding for unplanned diagnostic work. Both can apply on the same job at different times.
What licence and authorisation does the worker need?
The worker must hold the appropriate state electrical licence or registration for the class of work performed. State licensing varies: NSW issues an A-Grade Electrical Licence through Fair Trading; VIC issues an A-Class through Energy Safe Victoria; QLD issues an Electrical Work Licence through the Electrical Safety Office; WA, SA, TAS, NT, and ACT each have their own schemes. In addition to the base licence, live work typically requires written authorisation from the employer under the company Live Work Policy — not all licensed electricians are authorised live workers.
Is the safety observer requirement legally mandatory?
AS/NZS 4836:2023 specifies the role of a safety observer for live LV work and the Managing Electrical Risks Code refers to the standard. Compliance with AS/NZS 4836 is the practical benchmark inspectors apply, and once the Code becomes legally binding under WHS Act s. 26A from 1 July 2026, the standard's requirements effectively become the compliance baseline. The safety observer is a control measure recorded in this SWMS — record the observer's name and competency on the permit.
Does Victoria use this same SWMS framework?
Victoria operates under the Occupational Health and Safety Act 2004 and OHS Regulations 2017, not the WHS Act and WHS Regulation. The substance of the controls is similar, but the legal framing differs — the High-Risk Construction Work concept is replaced by the Construction Work Compliance Code, and the regulator is WorkSafe Victoria. The VIC variant of this SWMS substitutes the legislative references and Compliance Code citations at variant-generation time. The technical content (test-before-touch, PPE category, exclusion zones) is identical.
What if conditions change mid-task and the live work becomes unsafe?
Stop-work authority applies. Any worker may halt the live work without consequence if conditions change — for example, if the equipment behaves unexpectedly, if a worker becomes fatigued, or if an unauthorised person enters the exclusion zone. The permit is suspended, the work area secured, and the situation reviewed before any decision is made to resume. This is a control measure listed in the SWMS, not an optional backstop.
