Switchboard Upgrades

Switchboard upgrades — safe, compliant, future-ready

The switchboard is the electrical heart of your home. An outdated board — particularly one with ceramic fuses, minimal circuit breakers, or no safety switches — poses a real risk and may prevent you from safely adding modern appliances.

STRZELEC Pty Ltd handles switchboard upgrades from assessment through to energisation. We work with SA Power Networks for meter box modifications where required and ensure every upgraded board includes RCDs on all circuits as mandated under AS/NZS 3000:2018.

When to act

Smoke Alarm Compliance

SA smoke alarm compliance — sorted

South Australian regulations require working smoke alarms in all residential dwellings. Alarms must comply with AS 3786, be tested annually, and be replaced when they reach 10 years of age or fail testing. For rental properties and new builds, additional requirements apply — including interconnected photoelectric alarms on each storey.

STRZELEC Pty Ltd checks, tests, and replaces smoke alarms on every job. For jobs over $400, we replace units that are 10+ years old at a discounted rate. We issue compliance documentation where required for rental properties, settlement reports, or insurance purposes.

Combined with our home automation service, your smoke alarms can be integrated to trigger visual alerts — flashing lights throughout the house — for maximum safety.

Common Questions

Residential electrical questions answered

What Adelaide homeowners most often ask us about residential electrical work.

When does a residential switchboard need upgrading in South Australia?

Common triggers include: adding a new appliance circuit (EV charger, air conditioning, induction cooktop), rewiring work, solar installation, persistent tripping, ceramic fuses instead of circuit breakers, or the home being 25+ years old with an original board. Under SA regulations, any switchboard work must include RCDs on all circuits.

Do I need to upgrade my smoke alarms in South Australia?

SA regulations require working smoke alarms in all residential dwellings. Alarms must be replaced when they are 10 years old or fail testing. For rental properties and new builds, interconnected photoelectric alarms are required. STRZELEC Pty Ltd checks and replaces smoke alarms on every job and provides compliance reports where required.

How much does a switchboard upgrade cost in Adelaide?

A standard residential switchboard upgrade typically involves 4–8 hours of labour at our $140 per hour rate, plus materials. The total depends on the board size, number of circuits, and whether meter box work is needed. We provide a fixed-price quote before any work begins.

Can you add a power point or new circuit to an existing Adelaide home?

Yes. Adding power points, USB outlets, dedicated appliance circuits, or new lighting circuits to an existing home is one of our most common residential jobs. We assess your switchboard capacity first to ensure new circuits can be safely accommodated, and quote the full job including switchboard space if needed.

Do you install EV chargers in Adelaide?

Yes. We install dedicated EV charging circuits and charger units for residential properties. This typically involves a dedicated 32A or 40A circuit from your switchboard to the garage or driveway. We confirm your switchboard has capacity and coordinate with the charger supplier as needed.
