Understanding Your Switchboard

Research from Standards Australia describes the switchboard as the central control and protection point for home electrical systems. Understanding its components helps homeowners recognize safety concerns.

Key Switchboard Components (Research-Based Overview)

Main Switch

Technical specifications indicate this isolates entire property from electrical supply. Used during emergencies or by electricians during work. Typically rated 60-100 amps for residential properties.

Safety Switch (RCD)

Research shows RCDs detect earth leakage current and disconnect power within 30 milliseconds. Mandatory since 1991 for power points and 2018 for all circuits. Test monthly by pressing test button.

Circuit Breakers

Engineering literature describes these as overcurrent protection devices. Trip when circuit exceeds safe current levels. Each protects specific areas: lighting, power points, air conditioning, etc.

Surge Protection (if installed)

Technical studies show surge protectors defend against voltage spikes from lightning or grid fluctuations. Not mandatory but recommended by industry for electronic equipment protection.

Circuit Labels

Standards require circuits to be clearly labeled. Research shows proper labeling enables quick identification during emergencies and assists electricians during maintenance.

Meter Connection

Studies indicate this area is under Western Power authority. Only licensed electricians and authorized personnel may work near meter connections. Tampering is illegal and dangerous.

Monthly RCD Testing (Homeowner Task)

EnergySafety WA guidelines specify homeowners should perform this simple test:

  1. Locate your switchboard RCD (has a "TEST" button)
  2. Press the TEST button firmly
  3. The RCD should trip immediately, cutting power
  4. Reset by switching the RCD back to "ON"
  5. If RCD doesn't trip, call electrician immediately
Safety Standard: AS/NZS 3019 requires RCD testing every 3 months minimum. Monthly testing is considered best practice. Source: Standards Australia - AS/NZS 3019:2007
