How to tell when an older switchboard is due for an upgrade, and why it matters.
Last updated: 2026-06-20
Common signs a switchboard needs upgrading include old ceramic fuses instead of circuit breakers, no safety switches (RCDs), power that trips often, not enough circuits for modern appliances, or planning to add solar, a battery or an EV charger. A licensed electrician can assess your board and advise.
What your switchboard does
The switchboard is the heart of your home's electrical system. It distributes power to each circuit and is where the safety devices that protect you and your home live. Older boards were not designed for the number of appliances, or the safety standards, we expect today.
Signs to look for
Ceramic fuses or rewireable fuses rather than modern circuit breakers. No safety switches (RCDs) protecting your circuits. Power that trips frequently or flickering lights. A board that is full, with no room to add circuits. Scorch marks, buzzing or a burning smell, which should be looked at promptly. Planning a renovation, or adding solar, a battery or an EV charger, which often needs more capacity and protection.
Why upgrade
Safety switches are a key protection against electric shock and are standard in modern homes. An up-to-date board with the right circuit protection makes your power safer and gives you the capacity for solar, batteries, EV charging and modern appliances. A licensed electrician can assess what your home needs and do the upgrade safely and to standard.
