Did you know?
  • The original Rudolph did not have a red nose. In that day and age, red noses were seen as an indicator of chronic alcoholism and Montgomery Ward didn’t want him to look like a drunkard. To complete the original picture, he was almost named Reginald or Rollo.
  • The Christmas wreath was originally hung as a symbol of Jesus. The holly represents his crown of thorns and the red berries the blood he shed.
  • The three traditional colors of most Christmas decorations are red, green and gold. Red symbolizes the blood of Christ, green symbolized life and rebirth, and gold represents light, royalty and wealth.
  • Tinsel was invented in 1610 in Germany and was once made of real silver.
  • The oldest artificial Christmas trees date back to the late 1800s and were made of green raffia (think grass hula skirts) or dyed goose feathers. Next the Addis Brush Company used their machinery that wove toilet brushes to create pine-like branches for artificial Christmas trees that were less flammable and could hold heavier decorations.
  • ‘Jingle Bells’ – the popular Christmas song was composed by James Pierpont in Massachusetts, America. It was, however, written for thanksgiving and not Christmas.
  • Coca-Cola was the first company that used Santa Claus during the winter season for promotion.
  • Hallmark introduced their first Christmas cards in 1915.
  • The first recorded date of Christmas being celebrated on December 25th was in 336, during the time of the Roman Emperor Constantine. A few years later, Pope Julius I officially declared that the birth of Jesus would be celebrated on that day.
  • Santa Claus's sleigh is led by eight reindeer: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder (variously spelled Donder and Donner), and Blixem (variously spelled Blixen and Blitzen), with Rudolph being a 20th-century inclusion.
  • Outdoor Christmas lights on homes evolved from decorating the traditional Christmas tree and house with candles during the Christmas season. Lighting the tree with small candles dates back to the 17th century and originated in Germany before spreading to Eastern Europe.
  • That big, jolly man in the red suit with a white beard didn’t always look that way. Prior to 1931, Santa was depicted as everything from a tall gaunt man to a spooky-looking elf. He has donned a bishop's robe and a Norse huntsman's animal skin. When Civil War cartoonist Thomas Nast drew Santa Claus for Harper's Weekly in 1862, Santa was a small elflike figure who supported the Union. Nast continued to draw Santa for 30 years, changing the color of his coat from tan to the red he’s known for today.
  • Christmas 2018 countdown has already begun. Will you be ready???
  • Why do we love Christmas? It's all about the traditions. In this chaotic world we can miss the "good old days." Christmas reminds us of that time.

Sp2 Wire And Old X-Mas Light Plugs

Recommended Posts

Question....I use sp2 wire, has anyone ever used the plugs off of old nonworking x-mas lights by soldering them then putting heat shrink tape on them instead of vampire plugs when you in a pinch. Then the sp2 wire would be fused to....Would this work?????

I ran out of vampire plugs and only needed a few more. I cut the male and female plugs off old Christmas lights and did exactly what you said. I have had no problems.

Thank you for your answer ,  I didn't know if that would work or not, I'm in the same boat ,just two more to go THANKS AGAIN

First thing I do when I trash a set of mini lights is clip the male and female ends. Use them all the time.

Guess I'm the black sheep in the crowd...........I would be very,very careful doing that, remember sp2 wire is 18ga and light string wire is 22 or 24ga.......remember the sign on the light box, don't attach more that 3 strings together!!  Thats because of the small wire size of light strings

UL has not approved 24 gauge wiring for use in light strings for years........22 gauge is the most common{and minimum allowed by UL},with 3 amp fuses in the plug,and 20 gauge with 5 amp fuses is used in commercial or heavy duty light strings.

Well my point being is...........Thats not very many lights when using incans, so why bother .......and it's very easy to go over the in say when lighting a small tree let alone a wireframe etc etc.

OK I'm using LED'S , I have a AMP/WATT tester. The AMP'S being drawn are 00.3. Just using the male end ,Wouldn't you think the fuses would blow b/4 the wire got to hot to melt and electrocuted someone? I understand your concern gmac..But now I'm wondering why some say it's ok...and you say it's not... I don't see my factory x-mas light wires causing any problems, What would the difference be between extension cord and connecting them to the same thing right ? different wire sizes... Why couldn't a person just use a old strand for a cord??SORRY I'M JUST TRYING TO UNDERSTAND THIS ?????????????  SORRY, I didn't mean to start a argument..

Yes 00.3 would work but stop and think about how many people would stop there?  My dum dum neighbor pluged in strand after strand in the same line and couldn't understand why his breaker was tripping,,,I went over there and saw charred wood behind his wooden Christmas Tree the insulation was melted off and the bare wire was exposed and luckly no real damage but there had to be a small fire there.

If I understand you correctly your saying to use a old strand of lights instead of an extention cord ?  I don't even want to answer that .....all I say is ask the UL Labratories and see what they say.

MY WHOLE POINT  IS........... IT'S BETTER BEING SAFE THAN SORRY!!!   WE don't want to end up on the evening news as a Christmas Tragedy by buy trying to save a few cents.

I think solder + heat shrink tape + more of your time = a higher cost than buying a few more of the correct plugs.

The 20 or 22 gauge will not carry as much of a load as 18 gauge zip cord.  It would be important to keep that in mind when using cords made with the plugs from Christmas lights.

Your factory Christmas light wires aren't carrying the load of an 18 gauge extension cord.  I think the point is that using the Christmas light plugs will reduce the load that zip cord could normally carry.  There was a thread about how to convert old strings into extension cords.  The person who was doing it was only going to use them for LED sets so it would be a small load.

I use old light strands as extension cords all the time, my husband is an electrician and he says as long as i don't go over the load for the cord, i can use them, i plug 1 reindeer into an old cord and run it to the big extension cord. It saves us money on cords and when i plug to much into the light cord he lets me know. He says as long you watch what your plugging into them they are fine, after a few years of using one we throw it away.

Either way you go, you need to watch your amperage. If you are using un-fused vampire plugs and zipcord, there's no built-in device that would prevent you from overloading that cord to the point of failure. If you replace the vamp plug with a snipped plug using #20 or #22 wire, you've effectively reduced the ampacity of the cord. In theory, the fuses should provide some protection, but you have introduced a weak link into your cord.

 

There are risks either way, but careful load management and good workmanship would most likely minimize those risks.
