- We Fully Guarantee All Work
Looking for expert safety switch installation in Wollongong? Stuart Johnston Electrical Services is your trusted local electrician for RCD (Residual Current Device) installations, testing, replacements, and safety inspections.
We’ve been safeguarding homes and businesses across Wollongong and the Illawarra since 1995. Whether you’re upgrading an old switchboard or installing safety switches in a new property, our licensed electricians deliver safe, compliant, and fully guaranteed electrical work.
A safety switch, or RCD, is a life-saving device that detects electrical faults and shuts off power instantly to prevent electric shocks, fires, or fatalities. Unlike circuit breakers, safety switches monitor the current flowing through live and neutral wires — if a fault is detected, they disconnect the power in milliseconds.
Safety switches should be installed on all power and lighting circuits — in homes, offices, workshops, kitchens, and outdoor areas.
Yes. NSW law requires safety switches on all new homes and rental properties. Older homes without RCDs must upgrade during renovations, tenancy changes, or when installing new circuits.
Workplaces must comply with Work Health & Safety (WHS) regulations and ensure all employees are protected from electrical risks. Don’t risk non-compliance, insurance issues, or — worse — a preventable injury.
We check your switchboard and circuits and provide a clear, upfront quote.
Our electricians install or upgrade your RCDs with minimal disruption.
We test the system, label it, and issue compliance documentation where required.
Workplace testing frequency:
the frequency of appliance testing is covered in AS/NZ3760, though this standard is the minimum. WHS policies for individual companies can require testing in addition to this standard. We can help navigate this and organise programmed maintenance and testing for each situation.
We will remind you when testing is due, so you’re always covered.
Don’t leave your property or the people in it at risk.
