Dedicated Electrical Circuits

What is a Dedicated Circuit?
A dedicated circuit is an electrical cable for a specific use that is wired to its own circuit breaker in the main switchboard in your home or business.

Common Appliances that Often Need Dedicated Circuits (Some are legally required to be dedicated)

  • Electric Range
  • Wall Oven
  • Refrigerator
  • Microwave
  • Freezer
  • Dishwasher
  • Garbage Disposal
  • Kitchen Benchtop Power Outlets (Inset)
  • Toaster
  • Clothes Dryer
  • Clothes Washer
  • Heat pumps
  • Hot Water Cylinders
  • Garage Door
  • Sump Pump
  • Water Pump
  • Central Vacuum
  • Spa Pool/Sauna
  • Bathroom shaver power point
  • Blow Dryer

Not all Electrical Circuits are Not The Same

    • Outlets for small electrical appliances require 15-amp circuits.
    • Outlets for mid-range items, like hair dryers and toasters, require 20-amp circuits.
    • Heavy duty appliances like dryers can require anywhere from 30 to 50 amp dedicated circuits and are protected by “double pole” breakers. For safety reasons, certain medium and heavy duty appliances require their own circuit like ovens, stove & hot water cylinders

What Happens if I Don’t Have the Right Dedicated Circuits?
If you don’t have the appropriate dedicated circuit, an appliance or equipment may draw more current than the circuit can handle. This can cause the wiring to overheat and the insulation around the wire to breakdown or melt. Once the insulating barrier around the wire has melted, the current is no longer confined, and can ignite flammable materials within the wall leading to an electrical fire. Fortunately, circuit breakers sense the flow of excess current and stop the surge of current before damage takes place. If your circuit breaker is continuously tripping, as a safety precaution you should call our electricians to have a dedicated circuit installed.


If you are renovating your home or business, adding a new heavy duty electrical appliance or you simply need additional outlets, you will need new dedicated circuits.  Don’t risk the shutdown of critical appliances or worse – an electrical fire.
