Why Do My Christmas Lights Keep Blowing Fuses?

Putting up colorful Christmas lights has long been a tradition of the holiday season. For many people, these lights are a symbol of celebration and happiness. However, nothing can ruin the holiday spirit like Christmas lights that keep going out without warning. If your Christmas lights fuse bulb keeps blowing and you’re wondering what to do, you’ve come to the right place.

In this article, we will discuss why Christmas lights may keep blowing fuses and what you can do about it.

What to Do If My Christmas Lights Keep Blowing Fuses?

Using Too Many Strands of Lights

One of the common mistakes that homeowners make when putting up Christmas lights is chaining too many strands together. When you link too many strands of Christmas lights together, you may create a scenario where too many lights are trying to draw power from a single circuit. Overloading a single circuit can result in a blown fuse or a tripped circuit breaker. Additionally, frequent blowouts may happen if there are different strands in a chain that run on different amp sizes. If only one strand keeps going out, there’s a possibility that the strand is running on a different amp size.


You should avoid connecting too many strands together at once, as it could overload a single circuit. If you want to install multiple strands together, use several power outlets. You can call a nearby electrician to help you with holiday lights installation.

Using the Wrong Type of Christmas Lights

Using indoor-designated Christmas lights and extension cords outdoors can be a reason why Christmas lights keep blowing fuses. Indoor-designated Christmas lights and extension cords cannot be safely used in outdoor conditions.


Make sure you use the right type of Christmas lights and extension cords. If you plan to install the lights outdoors, ensure you use outdoor-designated lights and extension cords. Check the packaging on the Christmas lights you plan to install in your home so that you don’t choose the wrong type of lights.

Damaged Electrical outlet

A damaged or outdated electrical outlet can cause a power surge, which may lead to a blown fuse or a tripped circuit breaker. You’ll know your electrical outlet has gone bad if you notice the following signs:

  • Discoloration, scorching, or smoke on electrical outlets
  • Visible damage to the outlet
  • Plugs fall out easily out of the outlet
  • The covering of the outlet feels hot
  • Melted plastic
  • Odd smell coming from an outlet

If you’ve noticed any of these signs, call a professional electrician to help you with electrical outlet replacement. You should never ignore a faulty or malfunctioning electrical outlet, as it could lead to more expensive problems, including electrical fires.
