Switchboard Upgrades & Repair Melbourne

Your switchboard is the most important safety device in your home — and if it was installed more than 20 years ago, there’s a reasonable chance it’s no longer up to the job. Homes across inner Melbourne’s period suburbs are still running on ceramic fuse boards from the 1960s and 70s: boards with no safety switches, no circuit breakers, and no protection against the electrical loads of a modern household.

The symptoms are familiar: circuits trip when you run two appliances at once, fuses blow repeatedly, you’ve never had a safety switch test because there’s no safety switch to test. You know something needs to be done, but the process of getting it sorted has always felt overwhelming.

Luno Electrical upgrades switchboards across Melbourne’s inner suburbs every week. We’ve replaced hundreds of outdated ceramic fuse boards with modern consumer mains units — fitting circuit breakers and RCDs across every circuit, testing each one, and issuing a Certificate of Electrical Safety on completion.

We’re licensed master electricians registered with Energy Safe Victoria. We know the specific requirements for Melbourne’s period housing stock, and we do this work cleanly and efficiently — typically in a single day.

Ceramic fuse wire systems are a known fire risk. When a fuse blows and someone replaces it with a higher-rated fuse wire — or wraps it in foil — the overcurrent protection is gone entirely. Circuits can overheat without tripping. And a home with no safety switches has no protection against electric shock: a fault that would cause a brief trip in a modern home can be fatal in an unprotected one.

Beyond safety, an outdated switchboard limits what you can do with your home. Solar panels, EV chargers, ducted air conditioning and induction cooktops all require correctly protected circuits. An undersized or outdated board is the bottleneck that prevents all of it.

A modern switchboard means every circuit in your home is protected — by both a circuit breaker (protection against overload and short circuit) and an RCD (protection against earth faults and electric shock). The board has spare capacity for future additions. Your solar system or EV charger is correctly connected. And you have a Certificate of Electrical Safety that documents the work and protects you legally.

For the first time, your electrical system can handle everything you need it to.

Don’t wait for the fuse to blow again. Call Luno Electrical on (03) 9982 9737 or request a free switchboard inspection and quote online.

Commercial Switchboard Upgrades

Commercial switchboard upgrades are a core part of our work — from retail tenancy fit-outs requiring new sub-boards to heritage office buildings with outdated distribution panels. We install commercial switchboards, main distribution boards (MDBs) and sub-boards to AS/NZS 3000 standards, with full compliance documentation and co-ordination with your DNSP where required.

Switchboard Upgrades & Repair FAQs

How do I know if my switchboard needs replacing?

The clearest signs are ceramic fuse wire instead of modern circuit breakers, no safety switches (RCDs) on circuits, a switchboard that trips constantly, or a burning smell near the meter box. If your board was installed before 1990 and has never been upgraded, a professional inspection is strongly recommended.

How much does a switchboard upgrade cost in Melbourne?

Most residential switchboard upgrades cost between $800 and $2,500 depending on the number of circuits, whether it's a single or three-phase board, and whether the meter box needs to be moved. We provide a fixed price upfront — no variations unless you request additional work.

How long does a switchboard upgrade take?

A standard residential upgrade takes a full working day. Power will be off for most of the day while we work. We co-ordinate the timing with you and restore power before we leave. Work is completed in a single visit for most properties.

What our customers say

Andrew and the team installed a Tesla wall charger at my home. They did an outstanding job and went over and above to make sure everything was done professionally and worked properly. Before finding Luno I spoke to many electricians and they often hadn’t done an electric car home charger installation before and didn’t seem to know what was involved. Andrew and the team at Luno quickly put me at ease because it was clear they knew how to install electric car charging. Would highly recommend.

Andrew and Alex were very professional and friendly, they took measures to not leave mess and tidied up after themselves. They were thorough in asking if we wanted switches changed etc to look the best. We love our new fans and bathroom heating light. Thank you
