Switchboard Upgrades

Protect your family home – your biggest and most important investment. Safety switches save lives. Is your switchboard safe?

Voltair provides switchboard upgrades when required during installation of your air conditioning systems.

Signs your switchboard may need an upgrade:

  • Presence of rewirable, ceramic fuses – usually found in homes more than 15 years old
  • Crowded switchboard – an overcrowded appearance, or the recent addition of an air conditioner or pool pump etc.
  • Fuses that blow unexpectedly or circuit breakers that trip
  • Flickering lights

Upgrade options include:

  • New switchboard installation complete with safety switches
  • Single phase to 3 phase service – Larger homes may require a 3 phase power upgrade before a sufficiently sized air conditioner is installed
  • Installation of new dedicated circuits for larger electrical loads i.e. swimming pools, air conditioners, etc.

Protect your appliances from surges and your family from fire. Enjoy a consistent power supply and prepare to accommodate extra power demand.

  • Single phase air conditioners use a single phase power supply
  • Single phase power is used in most homes and small businesses because it is simple and inexpensive to install.
  • The largest capacity air conditioner you can install with single phase power is generally 16-18kw. Anything larger will require 3 phase power.
  • Sometimes a single-phase switchboard upgrade is required to allow room for a new circuit so as the air conditioner can be installed.
  • Voltair can take care of any switchboard upgrades as part of your air conditioner installation, making this a seamless experience and no need to involve a third party.
  • 3 phase power delivers power at a steady, constant rate.
  • Larger homes may require a 3 phase power upgrade before a sufficiently sized air conditioner is installed
  • Generally air conditioning units larger than 18kw will require 3 phase power.
  • Voltair can carry out 3 phase power upgrades if required. Steve is a licensed electrician, so we can carry out any needed upgrades seamlessly as part of your installation.
