Does a Space Heater Need a Dedicated Circuit?

Space heaters are great for keeping your energy bill low while still staying warm in the colder months. But if you have a 1500-watt or similarly high-wattage space heater and you notice it keeps tripping your breaker, you should consider installing a dedicated circuit. Electricians will install the additional circuit by connecting it to your current electrical system. Then you can connect your appliance to a dedicated outlet for safe and uninterrupted use.

What appliances need dedicated circuits?

The National Electrical Code requires that all major appliances have dedicated circuits including:

• Refrigerators
• Stoves
• Washers & dryers
• Space heaters exceeding 1500 watts

Space heaters can range from 400 to 1500 watts. A good rule of thumb is that the maximum watts per outlet should never exceed 1500 watts. In other words, yes, your 1500-watt heater needs its own circuit.

Why does my space heater keep tripping the breaker?

Portable space heaters use a lot of power and can overload circuits, cause breakers to trip, and even start an electrical fire. (This is also why you should never plug a space heater into a surge protector or an extension cord.) If your breakers trip when your heater is in use, then we recommend installing a dedicated circuit. This will help you stay safe while also ensuring that none of your other appliances are affected.

Bottom line: Space heaters can help you save money and keep warm, but always prioritize your safety when using them. For space heaters on the larger end, this means installing a dedicated circuit.
