3 Phase Switchboard Upgrade By Licensed Electricians

Before we recommend a 3 phase switchboard upgrade, we check whether you really need it.
Breakers tripping is often a supply problem rather than a single overloaded circuit issue. If the load assessment shows 3 phase is the right call, we quote the full scope.

What’s covered in your upgrade?

A 3 phase switchboard upgrade covers everything from the meter inward:

Consumer mains assessed for capacity and condition before pricing.
Hager protection devices in a B&R enclosure.
Phase load balanced across existing circuits.
Spare ways added while the board is open (cheaper than a return job).
Board tested and certified. CCEW lodged via BCNSW eCert portal within 7 days.
Lifetime workmanship warranty on labour. Parts under manufacturer warranty.

Pricing

Switchboard upgrades start from $1,200 + GST. Most residential 3 phase jobs fall between $4,000–$7,000+ depending on circuit count, mains condition, and whether asbestos removal is involved.

Your distributor bills separately for the street connection. We walk you through what to expect from them when we quote.

Your site inspection

For 3 phase jobs, we attend site first to check the meter box, mains conduit, existing board, and whether 3 phase supply is available at your street before anyone commits.

If access is difficult, we conduct a remote site inspection via photos and a short video call before quoting

When a 3 phase upgrade isn’t what you need

A dishwasher and washing machine running together can trip a 16A circuit without the supply being the problem at all. Then the fix is a circuit split. That’s a fraction of the cost of a full upgrade.

Single phase in NSW caps at 63 amps. That’s around 14kW. If your planned load pushes past this amount due to EV charging, ducted AC, a pool heat pump, and workshop equipment running together, 3 phase makes sense. If it doesn’t, we’ll be transparent.

Licensed and certified electricians

Every 3 phase switchboard upgrade is carried out under Contractor Licence 389893C.

The certificate of compliance is issued before we leave and lodged with Building Commission NSW. Your insurer and NSW Fair Trading both require it.

New homeowners and property investors can request a safety inspection at the same visit. Complimentary safety inspections are available for existing customers.

FAQs

Frequently asked questions

The street has power, but my whole house is out. What should I do?

Don't keep resetting the switchboard. If it trips again immediately, stop and call an emergency electrician nearby. Repeated resetting can mask a serious fault and create a fire risk.

Does the age of my home affect the price?

It can. Older properties sometimes reveal additional compliance requirements once we get into the work. Your emergency electrician in Riverview will discuss anything like that before proceeding.

Do you cover Riverview after midnight?

Yes. Our emergency electrician services in Riverview are available 24/7.

Can you do a safety inspection during the same visit?

Yes, where time permits. For existing customers, safety inspections are complimentary, which is a practical use of the visit if we're already on-site.

How do I know if it's urgent or can wait?

Call us. Burning smells, repeated tripping, scorch marks, or a total property blackout are urgent. Flickering lights or a single dead outlet can usually wait. We'll help you work it out.
