Old ceramic and rewireable fuse boards offer no RCD protection and are no longer compliant under AS/NZS 3000. If your power keeps tripping, your board buzzes, or you're adding an EV charger or heat pump, it's time to upgrade.

Many Hamilton homes still run on outdated boards. Upgrading to a modern switchboard with RCD protection makes your home safer, stops nuisance tripping and prepares you for higher loads like EV charging and heat pumps.

We replace your old board with a modern switchboard built to AS/NZS 3000, with RCDs protecting your circuits. Most domestic upgrades are completed in a day, with power off for the shortest time possible, and you get a certificate of compliance.

We check your board, loads and wiring and give a clear fixed price — no surprises.
We replace the board with a compliant, RCD-protected switchboard, power off only as needed.
We test every circuit, label it clearly and hand over your certificate of compliance.
A lot of Hamilton's housing stock — the older homes around Dinsdale, Glenview and Hamilton East especially — still runs on old ceramic or rewireable fuse boards with no RCD protection. If your lights flicker, your board buzzes, or your power trips whenever a few appliances run at once, that is a sign it is time to upgrade. JSK Electrical replaces these with modern, RCD-protected switchboards built to AS/NZS 3000.
An upgrade is not just about safety — it is what makes the rest possible. Adding an EV charger, a heat pump, a new kitchen or extra circuits all needs a board that can handle the load. Most Hamilton homes are done in a single day, with the power off for the shortest time possible, and you get a certificate of compliance. We give a fixed quote upfront so you know exactly what it costs.
