Sorry for the seamingly dumb question. I am new at PC and am looking to make some leaping arches for this year's display.

The question I have is: in order to connect the strings I an supposed to make my own extensions using SPT-2 wire and male/female connectors I get at HD/Lowes?? Is that safe for outdoor use?

Need a little guidance here please.

Yes I use the same wire all the time outside and it work great. You should also check into Action Lighting and the wire and ends that they have too. The cost is better. You have other options available for you also. Maybe multi conductor cable will work for you too.

Where in Texas are you we have some people all over Texas and we meet usually once or so a month send me a PM  or email for more info.

Depending on your load, you can use SPT-1 wire

I use spt-1 18ga on everything that is under 5A

Spt-2 16ga on 5A-10A - or the longer runs

There is a significant cost savings with using wire and putting your own ends on. I would shy away from the connectors from lowes/HD. Look online for  SPT - 1 (or 2) male or Female. These are designed for outdoor use.



I use these at work and have never had a problem. (we E-tape the connection)

Slightly off topic, but I think it will help answer the question - SPT rating has to do with the insulation thickness, not the size of the conductor.  see: http://planetchristmas.mywowbb.com/view_topic.php?id=5703&forum_id=13&jump_to=54188#p54188

true -

more commonly you will find SPT -1 in 18ga and SPT-2 in 16ga

and it is commonly refered to in that manner ( i have had problems ordering 18ga spt-2 - it came as a 1500' spool instead of 250 or 500' spools)

You can even go cheaper by cutting off the male plug, insert SP1/2, then reattach the male plug at the end.

I did this for my arches last week.  I heat shrank each individual conductor and then I put a larger hear shrink over those two.  Figure it's 120v so 2x the heat shrink is reasonable. :laughing:

Good tip!  That sounds nice and clean too, especially for a leaping arch type display where you don't really want all kinds of bulky plugs all over the place.

Take the time to maintain polarity (hot side / common side) when you cut off the plug and then reattach at the end of SPT2. While some mini-light strings don't have polarized ends, many do, and you ought to keep it as safe as possible. Be especially careful with strands like C9s and C7s because they are a full 120v.

Keep in mind the resistance of the wire that you use.  Depending on the length and amount of current being drawn you might blow the fuses or the lights might appear dimmer.

 That's a great idea!

I just bought 250' of SPT2 and will do that with the arches I'm building.

Thanks

I had a number of old light strands that were ready to be "retired".   I striped out the sockets and re-use the remaining pair of wire when I need to lengthen the plug end of a strand of minis.   This came in really handy while building arches.

Gil - Something to keep in mind - storage of the arches - extend the cords / connectors about 3 feet off the end of the arches, then use your SPT connectors to make your cords.  The cords wrap up in a tote real easy, and 3 feet on the end of the arches makes it easy to store - but yet gets your connections away from the end of the arch so you can put little stakes in the ground to get the connections off the ground so you don't trip out your GFCI's when it rains.

Hope your having fun with your new Leaping Arch Wrapper.  Remember to post some pics.
