When to Upgrade Your Distribution Board

You may need a switchboard upgrade if you notice:

  • Flickering lights or power surges
  • Fuses blowing or breakers tripping frequently
  • No residual current devices (RCDs) installed
  • Outdated rewireable fuses or asbestos backing boards
  • Plans to add high demand appliances, EV chargers, or solar panels

A new switchboard improves safety, load capacity, and efficiency, while ensuring compliance with current AS/NZS 3000 wiring standards.

Common Installations

We offer complete and compliant switchboard solutions for any type of property or power demand.

We commonly install:

  • Full switchboard replacements for homes and businesses
  • RCD and circuit breaker upgrades for modern protection
  • Three-phase power boards for commercial and high-load sites
  • Surge protection and metering integration
  • Solar and EV ready boards for future expansion

A modern switchboard not only protects your property, it’s an investment in safety, efficiency, and peace of mind.

Who needs to upgrade?

Distribution board upgrades are essential for anyone wanting a safer, more reliable electrical system. If your property is older, experiencing frequent power trips, or being renovated or expanded, an upgrade ensures your system can handle today’s electrical demands safely and efficiently.

This service is ideal for:

  • Homeowners in older properties still using rewireable fuses or non RCD protection improving safety and compliance.
  • Landlords wanting to meet current NZ Electrical Safety Regulations and provide safer living conditions for tenants.
