Switchboard upgrade in Auckland with RCD protection, usually done in a day
A modern switchboard with RCD protection is the safety backbone of a home. If yours still has fuses instead of circuit breakers, or no safety switch at all, it is due.
A residential switchboard upgrade in Auckland costs between $2,500 and $5,000 and is usually finished in a single visit with a short, planned power outage. Livewire Electrical replaces old fuse boards with modern circuit breakers and RCD safety switches on every circuit, then signs the job off with a Certificate of Compliance. Commercial and three-phase boards are quoted separately.

FAQs
Got questions? We've answered the most common ones here.
What safety regulations apply to switchboard upgrades in NZ?
Switchboard upgrades in NZ must meet current electrical safety requirements and be signed off with a Certificate of Compliance by a licensed electrician on completion. Major overhauls involving structural or significant capacity changes may also require additional permits. An electrician assessing the job upfront confirms exactly what applies to a specific property.
What is the difference between an old fuse box and a modern circuit breaker panel?
A fuse box protects circuits with replaceable fuse wire that has to be physically changed after it blows. A modern circuit breaker panel uses switches that trip and can simply be reset, and typically includes RCD protection that fuse boxes lack entirely. The safety gap is significant: RCDs cut power fast enough to prevent serious electric shock, which older fuse-only boards cannot do.
How long does a switchboard upgrade take?
A standard residential switchboard upgrade is usually completed in a single visit, with a short, planned power outage while the old board comes out and the new one is connected and tested. Commercial and three-phase upgrades take longer and are often scheduled outside business hours to avoid disrupting operations.
Is a switchboard upgrade mandatory for older NZ homes?
A switchboard upgrade is not automatically mandatory because a home is older, but it becomes necessary once the board cannot safely support the household's actual electrical load, or when other electrical work such as a rewire or major renovation triggers a compliance requirement. Insurers and buyers increasingly treat a modern switchboard with RCD protection as a baseline expectation regardless of legal minimums.
What are the signs an old switchboard needs upgrading?
A switchboard that needs upgrading typically has fuses instead of circuit breakers, no RCD (safety switch) protection, visible rust or heat damage, or trips repeatedly under normal household load. Switchboards in villas and bungalows built before RCDs became standard practice are common candidates, even if the board still technically works.
How much does a switchboard upgrade cost in NZ?
A residential switchboard upgrade in Auckland costs between $2,500 and $5,000. Commercial and three-phase switchboard upgrades cost more because of the higher capacity involved. The price depends on the number of circuits, whether RCDs need adding to meet current safety practice, and how accessible the existing switchboard is. Every upgrade is quoted as a fixed price after a site visit.
