Switchboard Upgrades — Noosa, Hinterland & Sunshine Coast
Ceramic fuses. Missing safety switches. Labels from the 80s. If that sounds like your switchboard, it's time for an upgrade — and we do it properly.
Your switchboard is the heart of your home's electrical system — and in many older homes across the Noosa Hinterland and Sunshine Coast, it's quietly working away with 1970s-era fuses, no safety switches, no surge protection, and zero capacity to handle a modern electrical load. Ultralec carries out compliant switchboard upgrades across Noosa, Noosaville, Tewantin, Cooroy, Pomona, Eumundi and Gympie — the kind of job that should be done once, properly, by a licensed electrician.
Why Upgrade Your Switchboard?
- Safety — modern RCBOs detect earth-leakage and overcurrent faults that old ceramic fuses can't
- Compliance — required before adding solar, EV chargers, ducted air conditioning or major renovations
- Capacity — older boards can't safely handle modern household loads
- Surge protection — protects appliances from lightning and grid switching events
- Reliability — fewer nuisance trips, clear labelling, easier fault finding
- Insurance — some insurers require compliant switchboards
What's Included in a Switchboard Upgrade
A proper upgrade replaces the old fuse board with a modern compliant switchboard including: main switch with appropriate rating, individual RCBO protection on every final subcircuit, whole-home surge protection device, clear circuit labelling, and optional provision for solar inverter connection or EV charger circuit. All work is completed to AS/NZS 3000 and current Queensland standards, with a Certificate of Electrical Safety on completion.
RCDs vs RCBOs
Older upgrades sometimes used shared RCDs protecting multiple circuits — meaning one fault trips several circuits simultaneously. Current best practice uses individual RCBOs (combined RCD and circuit breaker) on each circuit. A fault on your oven circuit trips the oven circuit only — not your fridge, not your lights. This is the standard we apply on every upgrade.
Switchboard Upgrade Cost
A full switchboard upgrade for a typical home runs between $1,800 and $3,500 depending on the number of circuits, surge protection inclusion, and condition of the existing installation. We provide written fixed-price quotes — call-out, assessment and quote are free.
How Long Does It Take?
Most residential switchboard upgrades are completed in a single day. We schedule a power-off window with you in advance — typically 4–6 hours — and restore power before we leave. The compliance certificate is provided on the day.

Typically 4–6 hours. We agree on a power-off window in advance and restore power before we leave. Most upgrades are completed in a single day.
Often yes — older boards frequently don't have the capacity or the correct protection for the additional load. We assess this as part of every solar and EV charger quote.
An RCD protects multiple circuits from one device — when it trips, several circuits go off. An RCBO protects a single circuit, so a fault only affects that circuit. Modern upgrades use RCBOs on every circuit.
