Specialist LV Switchboard and MCC Builder Since 1971

LV Switchboard Design and Manufacturing, New Zealand

At Clive Wilson Switchboards, every LV switchboard we build is designed from the ground up for your specific application, environment, and compliance requirements. We take a hands-on approach to every project, from initial design brief through to factory acceptance testing (FAT), ensuring your switchboard performs reliably from day one and for decades to come.

Built In-House. Controlled End-to-End.

Every main switchboard (MSB) and Motor Control Centre we manufacture is designed, built, and tested in our Invercargill workshop. Building in-house means we control every stage of quality, no outsourcing, no shortcuts, and full traceability on every assembly. Our ISO 9001-certified quality management system backs every board we produce.

Engineered to AS/NZS 61439, New Zealand's Mandatory Standard

All Clive Wilson switchboards are designed and manufactured to comply with AS/NZS 61439, the current mandatory standard for low voltage switchgear and controlgear assemblies in New Zealand. We build on four proven OEM platforms, Schneider Prisma, Simotrol, Quantum, and Logstrup, selecting the right system for your project's fault level, environment, and operational needs. For projects requiring automation and control integration, we design complete solutions from switchboard to PLC.

Is Your Existing Switchboard Fit for Purpose?

Many industrial and commercial operators are running ageing switchboards that no longer meet current standards, lack spare capacity, or carry maintenance risk. If your switchboard is approaching end-of-life, has been modified repeatedly, or was never properly commissioned, it may be time for a professional switchboard assessment. Common indicators include:

• Switchboard age exceeding 20–25 years
• No AS/NZS 61439 compliance documentation
• Inadequate fault level rating for current loads
• Lack of spare capacity for future expansion
• Exposed live busbars or deteriorating insulation
• Frequent tripping or unplanned outages

Our team can assess your existing switchboard and advise whether upgrade, modification, or replacement is the right path forward.

55 Years of Complex Switchboard Experience

Since 1971, we have designed and manufactured switchboards for some of New Zealand's most demanding industrial, infrastructure, and utility projects. Our experience spans large, complex switchboard systems for manufacturing plants, water and wastewater facilities, renewable energy installations including EV charging infrastructure, and government projects, giving us the depth to handle projects others can't.

Future-Proofed From Day One

A well-designed switchboard should give you 25+ years of reliable service with capacity to grow. Our designs incorporate spare ways, busbar capacity, and modular architecture so your power distribution system can expand as your operation does, without costly full replacements. We specify and size every board for your current needs and your next phase.

On Time. On Budget. On Standard.

We design and manufacture switchboards that are built to perform, not just to pass inspection. With ISO 9001 certified processes, Avetta registration, and SiteWise accreditation, we meet the procurement, quality, and health and safety requirements of NZ's most demanding clients, and we stand behind every board we build.
