Quick answer

A switchboard upgrade replaces an old ceramic fuse board with a modern metal-clad switchboard fitted with circuit breakers and safety switches (RCDs). Impulse Electrical carries out switchboard upgrades across the Mornington Peninsula, labelling and testing every circuit and issuing a Certificate of Electrical Safety.

A switchboard upgrade is one of the most important investments you can make in your home or business. Old ceramic fuse boards were designed for a fraction of today's electrical load — and they lack the safety protection that modern circuit breakers provide.

Frequently Asked Questions

How do I know if my switchboard needs upgrading?

The warning signs are clear: ceramic fuses instead of circuit breakers, no safety switches, fuses that blow frequently, a switchboard that feels warm or smells of burning, or plans to add a high-draw appliance like an EV charger or air conditioner. Any one of these is reason to have a licensed electrician assess the board.

What's included in a switchboard upgrade?

Impulse Electrical removes the old fuse board and installs a new metal-clad switchboard with modern circuit breakers (MCBs) and residual current devices (RCDs, also called safety switches). Every circuit is clearly labelled and tested, a Certificate of Electrical Safety is issued, and the work area is left clean and tidy — no mess left behind.

Are old ceramic fuse boxes dangerous?

They're a genuine safety concern. Old ceramic fuse boards were designed for a fraction of today's electrical load, and they lack the protection modern circuit breakers and safety switches provide. Without RCDs, there is nothing to cut the power quickly if a person contacts a live conductor. Upgrading brings the board up to current safety standards.

Do I need a switchboard upgrade before installing an EV charger or air conditioning?

Often, yes. High-draw appliances like EV chargers and air conditioners can push an old switchboard beyond what it was designed to handle, and many older boards can't safely accommodate the extra circuit. Impulse Electrical can assess your board, advise whether an upgrade is needed, and provide a free quote before any work begins.
