It’s space heater season, and I’m getting the calls for troubleshooting.
plugging a space heater into a standard 15-amp circuit can indeed be risky. Space heaters typically use a lot of power—often between 1,500 to 1,800 watts—pushing close to the upper limit of what a 15-amp circuit can handle. This can lead to overloading, overheating, and even electrical fires, especially if other devices are on the same circuit.
Here are some safer options to consider:
1. Use a Dedicated 20-Amp Circuit: A 20-amp circuit is better suited to handle the load of a high-wattage appliance like a space heater. Installing a dedicated circuit is a good solution, especially if you use a space heater frequently.
2. Limit Other Devices on the Circuit: If a dedicated circuit isn’t an option, try to minimize other devices running on the same 15-amp circuit while the heater is on. This reduces the chances of overloading.
3. Consider Heater Wattage: Choosing a heater with a lower wattage can reduce power demand, but it may not heat as efficiently. Some models have adjustable wattage settings, allowing you to use them at a lower setting.
4. Upgrade Wiring if Needed: If your home’s wiring is older or under capacity, an upgrade can make it safer to run high-draw appliances like space heaters.
Whenever possible, consult with an electrician if you’re uncertain about your home’s wiring or circuit limits.
