Switchboard Upgrades in Sunbury

Your switchboard is the heart of your home’s electrical system. It distributes power to every circuit in the house and, critically, it is where your safety switches and circuit breakers live to protect you from electrical faults and fires. If your switchboard is old, it may not be up to the job.

Norris Electrical upgrades old and outdated switchboards for homes across Sunbury and surrounding areas. Whether you have an old ceramic fuse board, a switchboard without safety switches, or one that simply cannot handle your home’s current electrical load, we will bring it up to current Australian standards safely and efficiently.

Safety Switches vs Circuit Breakers

A lot of people confuse safety switches and circuit breakers. They both live in your switchboard but they do very different things:

  • Circuit breakers – Protect your home’s wiring from overloads and short circuits. They cut power when a circuit draws too much current. They protect your property.
  • Safety switches (RCDs) – Detect current leakage to earth, which happens when a person receives an electric shock. They trip in milliseconds. They protect people.

Having circuit breakers is not enough on its own. You need safety switches too. Norris Electrical ensures your switchboard has both, correctly installed on all required circuits. See our safety switches page for more detail.

Signs Your Switchboard Needs Upgrading

Not sure if your switchboard needs attention? Here are the signs that it is time to call Norris Electrical:

  • You have a ceramic fuse board – These are extremely outdated and offer no real protection against electrical faults. Replace immediately.
  • Circuits trip frequently – Nuisance tripping suggests overloaded circuits or faulty breakers.
  • No safety switches – All modern homes must have safety switches. If yours does not, this is a serious safety concern that needs to be fixed.
  • Adding new appliances – Air conditioners, EV chargers, and solar systems often need dedicated circuits.
  • Burning smell or visible damage – This is an emergency. Call us immediately and do not use the affected circuits.

Every circuit is tested before power is restored. We provide a Certificate of Electrical Safety and walk you through the completed switchboard before we leave.

When Is a Switchboard Upgrade Needed?

Beyond the obvious warning signs, there are a few specific situations where a switchboard upgrade is typically required or strongly recommended:

  • Installing air conditioning – Most split systems need a dedicated circuit added to the switchboard.
  • Solar panel installation – Solar inverters require their own circuit and switchboard space.
  • EV charger installation – Electric vehicle chargers draw significant power and need a dedicated circuit.
  • Home renovations – Adding new rooms or wet areas often triggers the need for additional circuits and updated safety switch coverage.
  • Pre-sale inspection finding – An outdated switchboard flagged in a pre-purchase inspection is best dealt with before settlement.
