Dedicated Circuits

Top Appliances Need a Dedicated Circuit:

HVAC System

Well, you must know that HVAC system consume a lot of power and it require dedicated circuit. Cooling and heating systems need separate circuits. Approximately 15,000 watts is required to run a furnace, so it requires own circuit.

Electrical Oven

This is commonly used appliance in kitchens these days. This is a voltage powerhouse and need dedicated circuit with voltage of 240 Volt and a unique receptacle. Gas ovens have lower voltage, but they also need dedicated or own circuit to run properly without making any damage to electrical system.


No doubt, microwaves are available in many varieties and sizes, but they all need dedicated circuits. They must be plugged with a 120 V and a 20A receptacle. Some people plug them into standard circuits, but it can cause system overload.


This appliance is used 24/7 in almost every home. It works continuously and consume a lot of power. It requires constant power, so dedicated circuit is need to maintain that constant supply. They may need voltage of 120 V.


A washer and dryer mostly plugged into different receptacles. Voltage needed for this due may range from voltage 120 to 240V. More power is used by dryer as compared to washer. They both require own circuit due to proficient power consumption.

These above-mentioned appliances may draw more energy or current if they do not have own circuit.  Without dedicated circuits, overheating wire insulation, blowing fuses and tripping breakers will become common and it may lead to electrical fire.  Some other appliances that also need own circuits include saunas, hot tubs, central vacuums, water pumps, water heaters, furnace, heating and AC units, dryers, washers, toaster ovens, garbage disposals, dishwashers, freezers, large microwaves, refrigerators, wall ovens, electric ranges and more such appliances. You should consult with experienced electricians to get the job done.
