Understanding Your Homes Electrical Wiring

Typical homes will have an electrical outlet nearby the fireplace close by on the same wall. You usually won’t need to use an extension cord unless you have other devices already plugged into your closest outlet. If this is the case, try running other electrical devices to another plug, preferably one that is on a different circuit. Although your electric fireplace insert won’t use as many watts as say a dish washer or a fridge, it’s best to keep large appliances on their own circuit to prevent tripping your electrical panel.

Amperes vary by home and could be different based on the year your home was built. New homes often have a larger capacity to keep up with the technology rich generation that is always charging iPhones, tablets, and PC’s. Most homes use a 20 amp fuse for large appliance wall outlets. If you are unsure, you can open up your electrical panel and find the coordinating fuse to read it’s ampere measurement. Use caution any time you are around live wires and consult with a certified electrician if you have any doubts.

As stated above, extension cords should only be used on a temporary basis. Connecting an electric fireplace with an extension cord is ill-advised and just plain dangerous. In the case that you do end up using one for a short period of time, make sure that your extension cord meets these requirements:

  • 1,875 watts or more
  • 3 wire cord with a grounding plug connection
