Frequently Asked Questions
Why should I upgrade my switchboard?
Upgrading your switchboard improves electrical safety, supports modern appliances and helps prevent overloads and faults. Older boards often lack safety switches, which are essential for preventing electric shocks and fire risks. If your board still uses ceramic fuses, it's likely outdated and not compliant with current standards. An upgraded board provides better protection for your home or business, reduces the risk of electrical failure and ensures compatibility with future energy needs. It also allows for the addition of solar systems, EV chargers or air conditioning. A licensed electrician can assess your current setup and recommend the best solution.
Can I install a solar system without upgrading my switchboard?
Not always. Many older switchboards aren't equipped to handle the extra load from a solar power system. Before installation, a licensed electrician will inspect your switchboard to determine if it meets current safety requirements and has capacity for solar integration. If it doesn’t, an upgrade may be necessary to safely support the system and ensure long-term performance. This might include adding circuit breakers, RCDs and surge protection. Upgrading before installing solar also future-proofs your setup for battery storage or additional panels later on. It’s a smart step toward both safety and energy efficiency.
Is it safe to keep using an old fuse box?
Old fuse boxes with ceramic fuses can pose serious safety risks. Unlike modern switchboards with safety switches, these older systems may not trip quickly enough during a fault, increasing the risk of electric shock or fire. Fuse wire replacements can also be unsafe if done incorrectly. If your switchboard hasn’t been inspected in many years or you’ve noticed flickering lights, tripping circuits or burning smells, it’s time for an upgrade. Even if everything appears to work fine, age and wear can lead to hidden issues. A licensed electrician can check your system and recommend whether a modern upgrade is needed.
