Safer, Future-Ready Switchboards

Older fuse boxes and rewireable fuses can be unsafe and underpowered for today’s loads. We upgrade switchboards with modern circuit protection, tidy wiring, clear labelling, and space for future circuits like EV chargers, heat pumps, and kitchens.

Why Upgrade Your Switchboard?

S

Safety First

RCD/RCBO protection reduces electric shock risk and improves fault detection.

C

Capacity

Add circuits for EV chargers, heat pumps, induction cooktops, and renovations.

R

Reliability

Replace aging fuses and brittle wiring that cause nuisance trips and outages.

L

Compliance

Meet current NZ electrical standards and insurance expectations.

F

Future-Proof

Space and protection ready for solar, batteries, or additional circuits.

T

Tidy & Labelled

Clear labelling and neat wiring for easier maintenance and fault finding.

Common Signs You Need an Upgrade

  • Ceramic fuses or rewireable fuses still in use
  • Frequent tripping when multiple appliances run
  • Warm switchboard cover or burning smells
  • No RCD protection on power or lighting circuits
  • Planning EV charger, heat pump, or kitchen renovation

Our Switchboard Upgrade Process

  1. Assessment & Load Check

    We review your existing board, mains capacity, and planned loads to size the upgrade correctly.

  2. Recommendation & Quote

    We specify RCD/RCBO protection, enclosure size, and any mains or earthing upgrades needed.

  3. Installation

    We isolate safely, replace the board, reroute and tidy wiring, and install modern protection devices.

  4. Testing & Certification

    Full testing, labelling, and electrical certification for compliance and insurance.

  5. Handover

    We walk you through the new layout, labelling, and how to reset breakers.

What We Typically Include

RCD / RCBO Protection

Modern protection on power and lighting circuits for shock and fault safety.

  • Individual RCBOs where practical
  • Combined RCDs with MCBs as needed
  • Dedicated RCDs for wet areas

Capacity for Additions

Space and breakers for EV chargers, heat pumps, induction, and future circuits.

  • Load calculations for new circuits
  • Provision for solar / battery interfaces
  • Allowance for renovations

Mains & Earthing Upgrades

We address mains tails, earthing, MEN links, and bonding if required.

  • Check MEN/earthing integrity
  • Upgrade mains if undersized
  • Surge protection options

Tidy, Labelled Boards

Clean wiring, legends, and circuit schedules for easy future service.

  • Clear circuit labelling
  • Neat cable management
  • Documented schedules

FAQs

Most residential upgrades take 4-8 hours. We plan downtime with you and restore power as quickly as possible.

Not always. We assess your existing mains and only recommend upgrades if your planned loads (EV, heat pumps, induction) exceed capacity or if the mains are undersized or deteriorated.

Properly specified RCD/RCBO protection improves safety and, when circuits are separated correctly, reduces widespread outages compared to old shared circuits and fuses.

Yes. We can include Type 2 surge protection devices to help protect appliances and electronics from voltage spikes.

Yes. We test, certify, and provide documentation for compliance and insurance records.
