Frequently Asked Questions
What is an RCD or safety switch?
An RCD (residual current device) is a safety switch that disconnects the power supply instantly if it detects a current leak. This protects people from electric shock and reduces fire risk.
Do I need an RCD on every circuit?
Yes. In most modern installations, all final sub-circuits for power and lighting must be protected by RCDs under Victorian and Australian regulations.
What’s involved in wiring an RCD in Melbourne homes?
Wiring an RCD Melbourne jobs involve safely connecting the switch into the relevant circuit and ensuring proper trip sensitivity and circuit protection.
Can you install RCDs on older switchboards?
Yes. We can retrofit safety switches onto existing switchboards or recommend a full upgrade if the board is outdated or non-compliant.
How often should RCDs be tested?
We recommend manual testing every three months using the test button, with professional safety switch testing Melbourne every 12 months for residences, and more frequently for workplaces.
What does it mean if my RCD keeps tripping?
This usually indicates a fault in the wiring, an appliance, or the switch itself. We can diagnose and resolve the issue as part of our RCD service Melbourne offering.
Do rental properties need RCDs installed?
Yes. In Victoria, rental properties must have RCDs installed on all power and lighting circuits. We work with landlords and property managers to meet these obligations.
