You plug in the last strand of holiday lights, the front yard goes dark, and the breaker has tripped again. Holiday lights tripping the breaker means the circuit hit the current limit its wiring is rated for, so the breaker cut power before the wires overheated.
If you're asking how many Christmas lights on one circuit are too many, a wattage rule can give you the answer. Del-Air Heating, Air Conditioning & Refrigeration, LLC has served Florida homes since 1983 and offers a range of electrical services, so we also cover the times when the lights aren't the problem.
Call (844) 909-3003 or contact us online to schedule an electrician in Florida for a tripping breaker and holiday lights.
How Many Strands of Lights Fit on One Circuit?
A 15-amp circuit is rated for 1,800 watts. Lights run for hours, so keep the total under 1,440 watts (80 percent of the rating). A 20-amp circuit is rated for 2,400 watts, with a comfortable limit near 1,920.
Add the wattage tags near each strand's plug and compare the total to your limit. For instance, strands labeled 40 watts each fit 36 to a 15-amp circuit, assuming nothing else shares the wiring. In other words, total wattage sets the limit.
Some outdoor outlets share a circuit with garage lights, a freezer, or power tools, so subtract those loads first. LED strands draw far less power than older incandescent strands, which means more of them fit. If you don't know which outlets share a circuit, our electrical panel inspection can help you figure it out.
Why Do Holiday Lights Trip a Breaker?
A breaker is a safety device, and a tripped breaker is doing its job.
Holiday lights can trip a breaker or outlet when you have:
- Too many strands on one circuit – Lights, inflatables, and other loads add up, especially when you add decorations each season. We can add a dedicated circuit (a circuit feeding only your decorations).
- An overloaded extension cord or power strip – Daisy-chained cords push more current through a cord than its rating allows, which risks fire. Follow the manufacturer's strand limit, and we install outlets closer to your display.
- A damaged strand or cord – Storage leaves pinched wires, cracked insulation, and pest damage, and exposed conductors short out. Throw out damaged strands. However, if a new strand trips the breaker too, we can check the circuit.
- Moisture in outdoor plugs – Rain, sprinklers, and dew give current a path to ground, tripping a GFCI (ground fault circuit interrupter, an outlet cutting power when current leaks). We install outdoor GFCI outlets if yours trips in wet weather.
- A faulty connection – A loose plug or cracked socket trips protection: a short trips a breaker, a ground fault trips a GFCI, and an arc fault trips an arc-fault breaker. Our technicians can check each breaker's condition.
We tell you which fixes need attention now and which to plan for later.
Why Does Your Outdoor Outlet Keep Tripping After Rain?
A GFCI compares the current going out with the current coming back, and cuts power if even a small amount leaks to ground. Florida's afternoon downpours, sprinklers, and humidity give a wet plug plenty of chances to leak.
Look for TEST and RESET buttons on the outlet, because a tripped GFCI is not a tripped breaker. The breaker lives in your panel, and some homes build GFCI protection into the breaker. Press RESET once. If power stays on, you're fine.
If the outlet trips again, unplug every strand and reset with nothing connected. An outlet tripping empty needs an electrician. But if the outlet holds power, you can plug strands back in one at a time to find the damaged one.
When Should You Stop and Call an Electrician?
Repeated tripping, heat, or a burning smell point to your wiring, not your decorations. Don't swap in a bigger breaker, because the wire in your wall is sized for its breaker, and a larger one lets the wire overheat before power shuts off. Don't tape over or bypass a breaker either.
If you smell burning, unplug what you safely can, stay clear of the outlet, and call us. We offer 24/7 emergency support, and our licensed, bonded, and insured electricians arrive in fully stocked trucks, so we handle most repairs in one visit.
Stop and call a pro if:
- The breaker keeps tripping
- An outlet, plug, or cord feels warm
- You smell burning
- Lights flicker or buzz
- You're tempted to install a bigger breaker
Get Your Holiday Lights Back on Safely
With holiday lights, stay under 1,440 watts on a 15-amp circuit, reset a GFCI once, and call when the trip repeats. Del-Air Heating, Air Conditioning & Refrigeration, LLC handles electrical installation alongside plumbing and air conditioning, so we look at the whole home while we check the circuit. Reach out online or read our customer reviews first.
