WHY UPGRADE

Why Do I Need to Upgrade My Switchboard?

Upgrading your switchboard is essential for safety, compliance and the reliable operation of modern appliances. Key reasons an upgrade may be necessary:

✓Outdated ceramic fuses — these pose a serious fire risk and may result in electrical faults or electric shock. Home insurance providers may also reject fire-related claims if the switchboard is non-compliant.

✓Lack of safety switches (RCD/RCBOs) — older switchboards may only have basic circuit breakers, which do not protect against electric shock.

✓Rental property compliance — it is mandatory in Victoria to upgrade the switchboard in all rental properties to include safety switches.

CHECK YOURS

Does My Switchboard Need an Upgrade?

Yes, if any of the following apply:

✓Your switchboard contains ceramic rewireable fuses.

✓It only has circuit breakers, with no RCD or RCBO safety switches.

✓Only some of the final sub-circuits are protected by safety switches.

TIMEFRAME

How Long Does the Upgrade Take?

4–5 hrsTypical upgrade time

Most switchboard upgrades take approximately 4–5 hours to complete. During this time you will not have power.

CONSUMER MAINS

Consumer Mains (Main Supply Cable) Upgrade — When Do You Need It?

Some older homes have main supply cables sized at 6mm² to 10mm², which only allow a maximum current draw of 40A (for 6mm²) or 50A (for 10mm²). This is often insufficient for modern high-demand appliances such as electric ovens, air conditioning systems or electric hot water units.

You may need a consumer mains upgrade if:

✓Installing high-load appliances — if your maximum demand exceeds 40–50 amps, you will need to upgrade to a standard 16mm² supply cable to allow a 63A main switch.

✓Renovating — relocating the switchboard or replacing an outdated/wooden meter box may require a consumer mains upgrade.

✓Switching to 3-phase power — required for large homes or 3-phase appliances (e.g. EV chargers, ducted air conditioning).
