Safety Switch Installation Wollongong
Protect Your Home and Business from Electrical Hazards
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.

What Is a Safety Switch (RCD)?
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.
Why Safety Switches Are Essential
Electrical safety is not a luxury — it’s a legal and moral responsibility.
Every year, faulty wiring or electrical equipment causes hundreds of house fires and serious injuries across Australia. A correctly installed safety switch can:
- Prevent electric shock and electrocution
- Shut off power in milliseconds during a fault
- Reduce the risk of house fires
- Comply with NSW electrical safety laws
- Protect families, tenants, employees, and customers
Safety Switch Installation for Homes & Businesses
Whether you’re a homeowner, property manager, or business owner, we provide tailored safety switch solutions for:
- Residential homes & investment properties
- Strata & real estate managed buildings
- Commercial buildings & retail shops
- Warehouses, factories & workshops
- Schools, aged care & hospitality venues
From installation to replacement, testing, and emergency repairs, our electricians ensure you’re compliant and safe.
Is Safety Switch Installation Mandatory in NSW?
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.
Signs You Need a Safety Switch Installed or Replaced
- Your home or building has no RCDs installed
- Your switchboard is outdated or contains ceramic fuses
- You experience frequent power trips or shocks
- You’re adding new power points, lighting circuits, or appliances
- You’re renovating, selling, or leasing a property
If you’re unsure, we offer safety inspections to assess your electrical system and recommend upgrades.
