Switchboard upgrade: replacing an older fuse board (ceramic fuses, plug-in MCBs, or any pre-1990s board) with a modern RCD/RCBO-protected board sized for current and future loads. In NZ this is prescribed electrical work under the Electricity (Safety) Regulations 2010, and every job ends with a Certificate of Compliance (CoC) and an Electrical Safety Certificate (ESC).[1]
The Real Problem
Sam runs a two-person electrical contracting business out of Hamilton. He and his apprentice cover the Waikato: Hamilton, Cambridge, Te Awamutu, Morrinsville. Most of his work used to be new-build rough-ins for one of the big group housing companies. Today, more than half his quote requests are switchboard upgrades for existing homes.
It's the electrification wave. EVs need a 32A circuit. Heat pumps need their own circuit. Induction cooktops draw 7kW. Hot water cylinders are getting timed for off-peak. None of that fits into a 1985 Hager board with eight slots and a 60A main fuse.
Demand is fantastic. Conversion is awful.
A typical week looks like this:
- Tuesday afternoon: Sam drives to a 1990s home in Cambridge, photographs the existing board (12 ceramic fuses, four MCBs, no RCDs), counts circuits, traces the main run from the meter, asks the homeowner what they're planning (EV charger plus induction cooktop, eventually solar). 90 minutes on site. Drives back to Hamilton.
- Wednesday and Thursday: working on a commercial fitout in Te Rapa. No quote written.
- Friday evening, 9pm: kids in bed. Sam opens his laptop. Pulls up the photos. Tries to remember whether the meter box was zinc-flashing or fibre. Counts circuits from the photos. Decides on a 12-way Schneider Resi9 with full RCBO protection. Looks up wholesale pricing. Adds margin. Adds labour: full day plus apprentice. Adds council fee, CoC fee, disposal of the old board. Writes it up in Word, three pages. Emails it 11:40pm. Goes to bed.
- Monday morning: customer replies: "Thanks, but we've already gone with someone else. Their quote came through Wednesday and was $300 less."
Sam has lost a $4,200 job because he was six days behind a competitor who quoted off the photos on Wednesday afternoon.
The hidden cost is worse than the lost margin. Sam now has 14 photos of someone else's switchboard sitting in his phone, the homeowner's notes on a scrap of paper, the suburb-and-street written on the back of a Mitre 10 receipt, and no closure. Multiply that by four quotes a week, three of which lose, and Sam is doing 12 hours of unpaid quoting admin a week. To win one job.
Why Existing Tools Don't Solve This
Tradify, simPRO and Fergus all have quote templates and digital CoCs. They are excellent for the second half of the workflow: turning a written quote into an invoice, scheduling the job, generating the CoC, sending the ESC.[2] They do not help with the part that is killing Sam, which is the gap between the site visit and the customer's inbox.
The reason is that switchboard quoting is not data-entry. It's judgement. Which RCBOs go on which circuits. Whether the existing tails will cope. Whether the meter box needs replacing while you're there. Whether the main fuse will need an upgrade from the lines company (Wel Networks in the Waikato), which adds two weeks and $400 to the timeline. None of those decisions are in a template.
CERTIFi, Smart Certs and tradedocs.co.nz solve a different part of the problem: generating the CoC and ESC at the end of the job. Compliance documentation, not the quoting process.[3]
What sparkies like Sam actually need is something that listens to a 90-second voice memo on the way back to the truck: "twelve circuits, ceramic fuses, two ringmains, one stove, hot water on Tuya cylinder, 1985 brick and tile, meter box galvanised tin, main switch is a porcelain Eaton, customer wants EV plus induction plus future solar, 25-metre run from board to garage through ceiling cavity, no asbestos noted, parking is fine, dog is friendly", then turns it into a structured, priced, three-page quote in their drafts folder by the time they sit down with a beer.
That's not what existing job management tools are built for.
How AI Solves This
Your AI agent runs in the background. On site, Sam talks to his phone, a single voice memo of a minute or so as he closes up the meter box. By the time he's pulled out of the driveway, the AI has:
- Transcribed the memo.
- Pulled the matching site-visit booking from the calendar (so the address, customer name and contact details are already attached).
- Asked Sam two clarifying questions via SMS if anything is ambiguous. "Confirm: 12-way switchboard, full RCBO config? Any circuits to be left isolated?"
- Generated a draft quote using Sam's pricing rules: wholesale costs from his current PDH/Ideal/Corys catalogue, his own labour rates, his standard margin tier for residential.
- Attached the site photos to the quote PDF, labelled. ("Existing board, north-facing wall", "Meter box exterior: galvanised tin, 1985", "Main run path from board through ceiling cavity".)
- Flagged anything unusual that needs Sam's eyes before sending. "Main fuse is 60A. EV plus induction plus future solar will likely require an upgrade to 80A. Separate Wel Networks application required, estimated 2–3 weeks lead time. Quote includes $480 line item for application + lines work; recommend phoning customer to explain timing before sending."
When Sam opens his laptop on Tuesday at 4pm, there is a draft quote sitting in his email, ready to review. The line items are right. The pricing is right. The photos are attached. The PDF cover note already explains the RCBO-vs-RCD choice, why their old MEN system needs an updated bond, and the Wel Networks lead time.
He reads it, adjusts two prices, removes one optional line item, hits send. Six minutes.
The customer's inbox: 4:47pm Tuesday, same day as the site visit.
What the AI Knows
The AI pulls from your knowledge base. None of this is generic. It's Sam's actual quoting logic, captured during onboarding.

The AI never invents a price. It always uses Sam's current numbers, never last year's. It flags variables that matter rather than glossing over them.
How We Set This Up
The reason this works isn't just the chatbot. It's the integration we build to connect the voice memo, your calendar, your pricing book and your email, without you having to learn a new tool.
Here's what BestAI does for an electrician signing up for AI Agent:
- We capture your quoting logic. We sit with you for an afternoon and document how you actually quote switchboard upgrades. Which board you default to. How you decide RCBO vs RCD. When you flag a main fuse upgrade. What your margin rules are. What you always include separately. That becomes the knowledge base.
- We connect your calendar. Whether you use Google Calendar, Tradify's scheduler, Fergus or just a notebook on the dash, we write a custom program (an API connector) that links the AI to your booking system, so site visits and customer details are matched to the right voice memo automatically.
- We connect your pricing. Your wholesale catalogue (PDH, Corys, Ideal, whichever you use) gets imported. We can update pricing monthly so the AI never quotes from last year's figures.
- We integrate with your quote tool. If you already use Tradify or Fergus to send quotes, the AI drafts directly into your existing workflow, pre-filled and awaiting your review. You don't end up with two quote folders.
- We respect the human-in-the-loop. The AI never sends quotes on its own. Every quote lands in your drafts, ready for you to read, tweak and send. AI does the typing, you do the judgement.
You don't need to be technical. You don't need to know what an API is. That's what we are paid for. You run your electrical business. We run the software.
The Result
- Same-day quotes instead of week-late quotes. Most jobs go out within 4 hours of leaving the site. Customers compare your quote against the slow-quoter's empty inbox.
- Higher conversion at the same price. First detailed quote in tends to win, even at parity pricing.[4] Customers value responsiveness as a proxy for how the actual install will go.
- Saturday mornings back. No more 9pm Friday quote-writing sessions.
- Fewer pricing mistakes. Every quote uses current wholesale costs, current Wel Networks fees, current council inspection fees. No more "I forgot the disposal cost" surprises.
- Apprentice supervision unchanged. AI doesn't generate the CoC or ESC. That's still Sam's licensed signature, on his EWRB number, with his liability.
- Tribunal-grade audit trail. Every voice memo, photo and draft is timestamped and stored. If a customer disputes scope two years later, the original site notes are still retrievable.
What AI Can't Do Here
- AI does not size circuits or decide RCBO ratings. That's Sam's call, on his licence.
- AI does not issue the CoC or ESC. Prescribed electrical work in NZ requires a registered electrical worker to certify, full stop.[1]
- AI does not negotiate price or close the deal. The follow-up phone call, the "can you start before Christmas" conversation, the trust-building, that's all Sam.
- AI does not replace the 90-minute site visit. The visit is where the judgement happens. AI just makes everything that happens after the visit dramatically faster.
Who This Is For
- Registered electricians in NZ doing residential and small commercial switchboard upgrades
- Solo sparkies and 2–5 person teams who are losing evenings to quote admin
- Electricians who do good work, quote fairly, and keep losing jobs to faster quotes from less careful competitors
- Master Electricians members and EWRB-registered contractors who need their compliance trail (CoC, ESC, Worksafe notification) intact at the end of every job
- Anyone whose Saturday morning is supposed to be for the kids, not for re-photographing meter boxes from last Tuesday's site visit
