Reuben Saltzman, Structure Tech Home Inspections – Email– Minnesota Home Inspections They ended up using a neon transformer to set a tree on fire. What about the heat from the lights? Mythbusters already tried setting a Christmas tree on fire using only the heat from the bulbs. They’re hideously expensive, but they use 80% – 90% less power. What if 3,600 lights isn’t enough? Of course, a lot of people ask me this, and I always tell them to buy LED lights. Just remember to read the safety labels, and do some simple calculations if you think you’re using too many lights. As long as you’re using new lights, new extension cords and new power strips, you shouldn’t have much to worry about, and you shouldn’t have to do any math. The bottom line? All the blah blah blah advice you hear is right on. Twenty-four sets of lights would probably be safe at 12.96 amps, giving you a total of 3,600 lights. ![]() This could start the extension cord on fire. This means that if you plugged a power strip in to the end of the extension cord and ran 5 strings of lights (with 5 sets to a string), you would have a total of 25 sets pulling13.5 amps. This means that the power strip should be able to deal with anything I plug in to it – if I overload it, the circuit breaker in my electric panel will trip.Įxtension cord: I expected this to be the weakest link, but it’s not as weak as I thought the smallest extension cord I could find online or in the store was rated for 13 amps. Power Strip: I just took a look at a cheap power strip that I had lying around in my basement, and was surprised to see that the power strip was rated for 15 amps. Side side note: On that string of lights from 2002 there was one warning label. When stuff goes on clearance for 25 cents, I can’t help myself. These lights have been sitting in my garage for a long time. Side note: If you noticed the date code on the lights “08-02”, you got me. For the record though, I’ve always heard that you shouldn’t use more than three. Each string of lights has a 3 amp fuse built in to the plug, so you could potentially have five strings of lights plugged in to each other, end to end, to get 2.7 amps. This means that you could theoretically have 27 sets of lights plugged in to one circuit, and you would use 14.58 amps – just below the tripping point of a standard 15 amp breaker. Lights: I took a brand new string of 150 lights that I had sitting in my garage and examined the fine print on the warning label. I’m assuming the lights will be plugged in to a standard 15 amp outlet, and nothing else is running on that circuit (lighting, TVs, radial arm saws, etc.). I was curious what could really pose a threat if you’re using new lights and new extension cords, so I thought I’d do a little math and figure it out.Īs they say on the greatest TV show ever, : WARNING: SCIENCE CONTENT.Īs I see it, there are three main places for potential failure when installing Christmas lights – extension cords, power strips, and light cords. There are plenty of web sites out there offering all the same basic advice on Christmas light safety don’t use frayed cords, don’t use damaged lights, blah blah blah. ![]()
