Switchboards

Switchboard upgrades for Remuera homes

The switchboard is where every circuit in the house begins. In a Remuera home that has grown over the decades, gaining a kitchen here, a bathroom there, then a heat pump and garden lights, the board is often the oldest and most crowded part of the whole installation. We replace old fuse boards and full switchboards and arrange the inspection the work needs.

Why Remuera switchboards run out of room

Remuera's older houses have rarely stood still. The Remuera Heritage society describes villas and bungalows that have been modernised with new kitchens, bathrooms, decks, swimming pools and garages while keeping their character, and each of those changes usually meant another circuit. Add a heat pump in two or three rooms, an oven and cooktop on their own circuits, a garage with power, and lighting out in the garden, and a board that was laid out for a handful of lighting and power circuits is asked to carry several times that.

When a board fills up, the shortcuts start: two circuits doubled onto one fuse, a heavier fuse wire fitted because the old one kept blowing, a sub-board added in a cupboard without anyone recording it. None of those is visible from the hallway, and all of them are reasons a modern switchboard is worth the change.

One more circuit at a time

A bathroom renovation is a typical example. The old room had a light and perhaps a heater; the new one has downlights, an extract fan, a heated towel rail and a heater on the wall, and possibly heating under the tiles. A heat pump installation elsewhere in the house usually needs a dedicated circuit of its own as well.

Where the board has spare space and sound wiring behind it, a new circuit can simply be added. Where it has neither, the sensible answer is a board with room to grow, and often a look at the age of the wiring behind it while the cover is off.

What a new switchboard gives you

Circuit breakers, not fuse wire

A breaker trips and is reset with a switch. There is no fuse wire to replace in the dark, and no way to fit the wrong size.

RCD protection

A residual current device cuts the power in a fraction of a second when current leaks to earth, the kind of fault that gives a person a shock.

Every circuit labelled

So the right circuit can be turned off for work, or in a hurry, without switching off the whole house.

Room to grow

Inspection, certificates and the line to the street

Changing a main switchboard is not a job that ends when the cover goes back on. WorkSafe's guide to getting electrical work done explains that the law requires some work to be inspected, particularly work on the main switchboard, the main cable and the main earth, and that the electrician you employ is responsible for arranging a licensed electrical inspector. We arrange that inspector for you. Once our work is tested you receive its certificate, and the inspection report belongs in the same folder.

It also helps to know who owns what. Vector generally owns the network up to the point of supply, usually an isolating fuse on your boundary or on the nearest pole. The service line from there to your meter is the property owner's, and Vector says the meter is the responsibility of your electricity retailer, so moving a meter involves the retailer as well as the electrician. On a long driveway or a rear section, the condition of that service line is worth checking at the same time as the board.

Switchboard questions

How can I tell if I still have fuses?

Open the switchboard cover. White or brown ceramic holders that pull out are rewireable fuses; a row of small switches is circuit breakers. Some boards have both, which usually means circuits have been added over the years.

Can more circuits just be added to my old board?

Sometimes, if there is space and the board and its wiring are sound. An old ceramic fuse board with no room left is usually better replaced than extended.

Will the power be off while the board is changed?

Yes, the whole house is off while the switchboard is changed over, so the day is planned with you in advance. Fridges and freezers are worth keeping closed until the power is back.

Who is responsible for the meter on my switchboard?

Your electricity retailer, according to Vector. If a new board means the meter has to move, the retailer is part of the job.

Does a new switchboard mean a full rewire?

Not necessarily. A new board can be fitted to existing circuits that test sound. If the testing turns up perished cable, we will tell you which circuits need attention and why.
