Safety Switch (RCD) Installation SWMS

For licensed electricians and electrical contractors who add or replace safety switches (residual current devices) and RCBOs in existing switchboards. It follows the job in order, from surveying the board and isolating the supply to proving dead, wiring, testing, certifying and handover, and states the safety switch rules in the Electrical Safety Regulation 2026 for homes and workplaces.

Installing a safety switch in an existing switchboard is construction work (WHS Regulation s 289), and testing for dead and trip testing, with the supply side of the board still live, is work on or near an energised electrical installation, so item 10 is ticked. Tick asbestos (item 3) if the job will disturb asbestos in the board or its mounting, and the fall item (item 0) if a person could fall more than 2 metres. Use a separate energised electrical work SWMS for any live work beyond testing (Electrical Safety Regulation 2026 ss 195 to 204).

What Is Covered In Our Safety Switch (RCD) Installation SWMS?

After the standard pre-start checks, the job steps run from “Plan the job and survey the switchboard” to “Respond to electric shock, arc flash or fire at the board”. The hazards and controls include:

• Electric shock from live supply-side parts that stay live after the main switch is off
• Switchboard circuits not isolated or switched back on
• False dead readings from shared neutrals and faulty test instruments
• Arc flash while testing or restoring power
• Wrong circuit identification in old boards
• Incorrect wiring of neutrals through new safety switches
• Safety switches that fail to trip left in service
• Asbestos in old mounting boards and linings
• Falls from ladders next to the board
• Poor labelling and test records at handover

High Risk Construction Work

These high risk construction work items (WHS Regulation 2011 (Qld) s 291) are already ticked because they are part of this work. Tick any others that apply to your job:

• Is carried out on or near energised electrical installations or services

Licences, Training and Competency

• Electrical work licence that authorises the work: installing, replacing, connecting and testing a safety switch is electrical work (Electrical Safety Act 2002 s 18(1)), and only a licensed electrical worker may perform or supervise electrical work (s 55); the business holds an electrical contractor licence (s 56)
• Rescue and resuscitation competence for every worker who does or helps with electrical work, and for the safety observer (Electrical Safety Regulation 2026 s 211 and sch 10)
• Competent person to carry out the recorded risk assessment and to test whether equipment is energised (Electrical Safety Regulation 2026 ss 196 and 199)
• Apprentices perform electrical work only as their apprenticeship allows (Electrical Safety Act 2002 s 55(3)(e)), supervised at all times by a licensed electrical worker licensed to perform the work, and an apprentice in the first 6 months never works where they could contact a live low voltage exposed part, such as the supply side of the board (Electrical Safety Regulation 2026 s 307); other unlicensed workers do no electrical work and never touch the board or energised equipment
• General construction induction training card (white card) for construction work
• Asbestos awareness so every worker recognises suspect mounting boards and linings, stops and reports; training under WHS Regulation s 445 for workers who may be involved in asbestos-related work
• Training in the isolation and lock-out procedure and in the test instruments in use, including the RCD tester
