Why Clive Wilson

Why Industrial NZ Specifies CWS for Switchboards

Specifiers and procurement teams pick Clive Wilson because the switchboard arrives on site with the documentation, compliance pack, and engineering integrity that procurement audits expect. We have been building industrial LV switchboards in Invercargill since 1971.

50+ Years in Invercargill

Family-owned switchboard manufacturer since 1971. Most of our team has decade-plus tenure, and senior staff have 30+ year careers on the workshop floor.

ISO 9001-Certified QMS

Audited annually since 1995. Every drawing reviewed, every torque logged, every routine test signed off by a registered electrician.

AS/NZS 61439 Verified

Designed and verified to the mandatory NZ standard. Full compliance pack delivered with every project: type-test certificates, fault calculations, segregation photos, routine verification.

Four OEM Platforms

Schneider Prisma Plus G accredited builder, Simotrol primary platform, Logstrup for higher-rated work, Quantum for custom enclosures. Platform selection is duty-led.

FAT Witness Programme

Operator and consulting engineer attendance at our Invercargill workshop before delivery. Functional verification before the board ships reduces site commissioning risk.

Nationwide Delivery

Built and FAT-tested in Invercargill, then delivered nationwide. Remote-site freight, oversize permits, and on-site offload coordination handled in-house.

Common Questions

Switchboard Buyer FAQs

The questions specifiers and procurement teams ask first. For the full list see our switchboard FAQs page.

How long does a typical switchboard take to manufacture?

Typical lead time is 8 to 16 weeks from engineering sign-off to factory acceptance test, depending on size and platform. Distribution boards on Schneider Prisma Plus G run 8 to 12 weeks. Mid-size MSBs and motor control centres on Simotrol run 10 to 16 weeks. Larger MSBs on Logstrup at 4,000A and above run 16 to 20 weeks. Custom Quantum work runs 14 to 22 weeks.

What information do you need to quote my switchboard?

For a tight quote we need: single-line diagram showing the incoming feeder and outgoing feeders, schedule of loads with motor sizes and starter types, fault level calculation from the lines company, form of segregation specification, enclosure rating (IP and IK), and platform preference if any. If you do not have all of those yet, send what you have and we will tell you what is missing.

What standards do you build to?

AS/NZS 61439.1:2016 and AS/NZS 61439.2:2016 are the mandatory NZ standards. Plus AS/NZS 3000 wiring rules, ISO 9001:2015 quality management certified annually since 1995, and the Health and Safety at Work Act 2015. Every board ships with the full compliance documentation pack: type-test certificates, project-specific short-circuit calculations, Form-of-segregation verification photos, and routine verification certificates.

Do you maintain switchboards you did not build?

Yes. Our maintenance team services all major LV switchboard platforms across NZ, including older Schneider Prisma, Simotrol, Logstrup, ABB, and other industrial platforms. We do scheduled maintenance, thermographic inspections, ACB retrofits to extend the life of older boards, and emergency response. View our maintenance capability →
