Why Upgrade Your Switchboard

Signs You Need Switchboard Upgrade

Old Fuse Box

If your property still has a fuse box with ceramic fuses, immediate replacement is essential. Fuse boxes lack modern safety features including no RCD protection against electric shock, fuses that can be replaced with incorrect ratings, no surge protection, and inadequate capacity for modern loads. Old fuse boxes are insurance concerns and create serious safety hazards. We replace all fuse boxes with modern circuit breaker switchboards including safety switches. For complete electrical safety, combine with safety inspections and smoke alarm installations.

Circuit Breakers Tripping

Frequent circuit breaker trips indicate overloaded circuits or switchboard problems including insufficient circuit capacity for electrical loads, damaged or faulty circuit breakers, loose connections creating arcing, or circuits loaded beyond safe limits. Persistent tripping requires professional assessment. We evaluate electrical loads and recommend switchboard upgrades with adequate circuits. Never replace circuit breakers with higher-rated units without professional assessment - this creates fire hazards. For urgent issues, contact our emergency electrician.

No RCD Protection

Modern regulations require RCD (Residual Current Device) safety switches protecting against electric shock. Switchboards without RCDs lack essential protection. RCDs detect current leakage and disconnect power within milliseconds preventing electrocution, protect all power point circuits, protect lighting circuits where required, and are mandatory for new electrical work. We retrofit RCD protection to existing switchboards or install new switchboards with comprehensive RCD coverage. RCD protection is essential safety equipment all homes should have.

Insufficient Capacity

Modern homes use more electricity than older electrical systems can safely supply. Signs include needing to turn off some appliances to use others, lights dimming when appliances start, inability to add new circuits for renovations, and switchboard physically full with no spare ways. We upgrade switchboards to larger capacity units with space for additional circuits supporting modern electrical demands. For homes adding power points, air conditioning, or major appliances, switchboard upgrades often are necessary.

Switchboard Upgrade Process

1. Assessment and Planning

We assess your electrical system and switchboard requirements including inspecting existing switchboard condition and capacity, calculating current and future electrical loads, identifying safety hazards and code violations, determining optimal switchboard size and configuration, and preparing detailed quote with upgrade specifications. This assessment ensures proper switchboard sizing and identifies all required work.

2. Installation

Our electricians complete switchboard upgrades professionally by arranging planned power disconnection with energy provider, safely removing old switchboard, installing new switchboard enclosure and mounting, transferring circuits to new switchboard with modern protection, installing RCD safety switches on required circuits, labelling all circuits clearly, and testing all circuits and protection devices. We coordinate with energy providers ensuring minimal power outage duration. For new construction or major renovations requiring complete electrical systems, see our electrical installation services.

3. Testing and Certification

Before re-energising, we comprehensively test the installation including insulation resistance testing of all circuits, earth continuity verification, RCD trip time testing, polarity testing, and circuit load verification. We provide electrical safety certificates and compliance documentation. All switchboard upgrades meet Australian Standards AS/NZS 3000 requirements. For properties requiring broader electrical compliance including downlights and ceiling fans, we coordinate complete upgrades.

Switchboard Components

RCD Safety Switches

RCD safety switches are mandatory protection devices detecting dangerous current leakage. We install RCDs protecting all power point circuits throughout property, lighting circuits where required by regulations, outdoor circuits and wet areas, and circuits supplying portable equipment. RCDs must be tested regularly - modern RCDs include test buttons for monthly testing. We install Type A RCDs for circuits with variable speed drives or solar inverters requiring enhanced protection. RCD protection dramatically reduces electrocution risk and is considered essential safety equipment.

Surge Protection

Whole-house surge protection protects against voltage spikes from lightning strikes, power grid switching, and electrical faults. We install surge protection devices (SPDs) in switchboards protecting computers and electronics, appliances and equipment, LED lighting systems, and solar inverters and batteries. Quality surge protectors significantly extend equipment life and prevent expensive damage. Surge protection is particularly important for homes with sensitive electronics or valuable equipment.

Switchboard Types and Sizes

Residential Switchboards

Residential switchboards range from 8-way to 36-way capacity. Standard homes typically need 12-18 way switchboards providing adequate circuits for lighting circuits throughout home, power point circuits for different areas, dedicated appliance circuits, air conditioning circuits, and spare ways for future additions. We recommend switchboards with 20-30% spare capacity allowing future electrical additions without switchboard replacement. Larger homes or properties with extensive electrical systems may require larger switchboards or sub-boards.

Three-Phase Switchboards

Properties with three-phase power require specialised switchboards with three-phase main switches and circuit breakers, single-phase circuits distributed across phases, three-phase circuits for equipment requiring three-phase, and RCD protection on all phases. We install three-phase switchboards for homes with large air conditioning systems, commercial equipment, workshops with machinery, and electric vehicle charging. For complete three-phase installations, see our three-phase power services.

Sub-Boards

Large properties or additions may require sub-boards distributing power to specific areas. We install sub-boards for granny flats and separate dwellings, large sheds and workshops, pool and outdoor entertainment areas, and renovation additions. Sub-boards connect to main switchboard via sub-main cables sized appropriately for distance and load. Each sub-board includes its own main switch, circuit breakers, and RCD protection. Sub-boards simplify circuit distribution and reduce cable runs.

Commercial Switchboard Upgrades

Business Electrical Requirements

Commercial properties have different electrical requirements than residential including higher electrical loads and capacity, three-phase power distribution, dedicated circuits for equipment, emergency lighting circuits, and compliance with workplace safety regulations. We upgrade commercial switchboards to meet business electrical demands ensuring adequate capacity, proper protection, and code compliance. For comprehensive commercial services, visit our commercial electrician page.

Industrial Switchboards

Industrial facilities require heavy-duty electrical distribution including large main switches handling high currents, motor control circuits with appropriate protection, three-phase power throughout facility, and compliance with industrial electrical standards. We install industrial switchboards for warehouses, factories, workshops, and commercial facilities. Industrial switchboards require specialist knowledge ensuring correct protection device selection, cable sizing, and safety compliance.

Switchboard Maintenance

Regular switchboard maintenance ensures continued safe operation including monthly RCD testing using test buttons, visual inspection for signs of damage or overheating, checking circuit breaker operation, ensuring tight connections throughout, and professional inspection every 5-10 years. We provide switchboard maintenance services identifying problems before they become hazards. Never open switchboards yourself - live electrical connections create electrocution hazards. For any switchboard problems, contact licensed electricians. For ongoing maintenance, consider our electrical repair services.

Switchboard Upgrade Pricing

Switchboard upgrade costs vary based on switchboard size and capacity required, number of circuits being transferred, whether three-phase or single-phase, additional components like surge protection, accessibility and installation difficulty, and energy provider disconnection fees. We provide transparent fixed-price quotes covering all required work.
