The Switchboard Upgrade Package

With all the creature comforts of modern living, power usage in most houses has more than doubled from 30 years ago. Back when your switchboard or fuse board was installed, the appliances in most households were kept to a minimum. Now we have 1kilowatt flat screen TVs (sometimes a couple per house), convection ovens, multiple air conditioners, pool pumps, and more appliances to give you the creature comforts you demand. In a lot of houses the amount of lights has quadrupled from one wall light to 4 down-lights per room. Not only does this put a strain on your wallet (unless you have LED lighting)  but your circuit protection as well.

Is your switchboard up to the task?

Outdated switchboards are highly prone to short-circuits. Their fuses are more harmful as those fuses tend to catch and spread fire easily. Also there is more chance of electric shock with these old boards.  Everything in life has a use–by date. Whether it’s a litre of milk or a car or your switchboard, nothing lasts forever. If you have old ceramic fuses or old breakers, you really should consider upgrading to a safer option.

Here’s what we include in our Switchboard Upgrade package

  • ‘Up to’ a 14pole switchboard (single phase)
  • 1 x 80amp main switch
  • 2 x 40amp RCD’s
  • 3 x 20amp circuit breakers (power and aircon)
  • 2 x 16amp circuit breakers (lights)
  • 1 x 32amp circuit breaker (stove)
  • 1 x 25amp circuit breaker (hot water system)

We can also offer you the following extras:

  • 1 x Novaris 50KA surge diverter (optional extra)
  • 1 x 24hour timer and contractor (optional extra power saver)

With our switchboard install package, you have the option to upgrade with a hot water system timer or surge diverter. Did you know your hot water service can use up to a quarter of your electricity in most households? A timer will be a great saving. You can even upgrade further for our top of the range full house protection surge diverters, for protecting expensive computers, big TV’s, newer style ovens or dishwashers and other electronics.  More and more these appliances are being affected by surges.
