Why Regular Switchboard Checks Matter (Especially in Old Central Otago Homes)

29 May

Many homes around Wanaka, Albert Town, and the wider Central Otago region were built long before today’s electrical safety standards. Even homes from the early 2000s can have switchboards that are outdated, overloaded, or missing crucial safety devices.

If your switchboard doesn’t have RCDs: it’s time to upgrade.

A switchboard is essentially the “heart” of your home’s electrical system — and if it isn’t functioning properly, it can create real safety risks.

Here’s why regular checks (every 3–5 years) are essential.

1. Older Homes Weren’t Designed for Modern Loads

Central Otago homes built in the 80s, 90s, and early 2000s typically weren't designed for:

EV chargers
Heat pumps in every room
Underfloor heating
Large ovens + induction cooktops
Spa pools
Home offices

This extra load can strain old switchboards and wiring.

2. Many Older Boards Don’t Have RCD Protection

RCDs (Residual Current Devices) save lives.

They detect earth faults and cut the power instantly — far faster than old fuses or breakers.

3. Signs Your Switchboard Needs Attention

You should get your switchboard checked if you notice:

Flickering lights
Breakers tripping often
Warm/humming switchboard
Burning smell
Ceramic fuses
No labelling or messy wiring
A board older than 20–25 years

These are indicators of overloaded or unsafe circuits.

4. Peace of Mind for Renovations or Extensions

If you're adding a new room, heat pump, or doing any renovation work around Wanaka, your switchboard may need:

Extra capacity
RCD protection
A full re-wire of certain circuits

We assess this during a switchboard check so we can plan the safest, cleanest solution.
