A couple of weeks ago Lowes had rolls of 16/2 SPT-2 250' for $27.94

That's a petty good price. I work for a distributor and pay cost for whatever I need from work and I can't touch that price.

The skycraftsurplus.com stuff was 18g. Is that what the Zip cord from CDI is?

dose anyone know if they still have it? & dose he mean 250 ft.?

Judging from the price, that sounds about right. Last time I bought a 250 ft. roll, that was approx. the price.

I haven't been back to Lowes since I saw it originally, but it was 250' of 16-2. HD has rolls of 18 gauge for a little more.

Hi all, any idea where I can get something similar (18 Awg Lamp Cord, Brown, SPT-2) in bulk, but outdoor rated?
Thanks

I'm having a senior moment... (which a 60 year old guy is entitled to have once in a while) and I can't seem to find a chart that cross-indexes lamp cord, sp1, sp2, gauge and amperage ratings. Lots of charts that say, "if you have 18 gauge, it can handle X chassis amps and Y transmission amps..." which is fine if you know what gauge wire you have. However, if you DON'T... arghhhh

My brain isn't working with my Google searches -- or here, either!!!

Anybody have a quick, down-n-dirty chart???

-dirknerkleNot sure if this is what you're looking for, but here is what the National Electric Code says about it: http://ftp.resource.org/bsc.ca.gov/title24_part03_dice/title24_part03_page0292.pdf

Keep in mind that the 1 or 2 in SPT1 and SPT2 has nothing to do with its current carrying capacity, it is just the thickness of the insulation.

Thanks -- that's just what I was looking for! Now I can just go back to being a senior and not having a clue in general -- at least according to my kids...

Hey All

So i have read that SPT2 isn't cannot handle UV rays. I know as a kid i always got away with using whatever extension cords i could find. But that was on a small scale, now i am bigger and my display is much bigger. This will be my first serious year. I was hoping to get some quick advise about the cheap SPT2 wire everyone talks about. (I got some of the cheap stuff at lowes.) How many seasons has someone ran using this wire before seeing insulation breakdown that caused them to get rid of the wire?

Also i was thinking, i have old paint lying around, maybe i could do a quick dip treatment?

Anybody else have suggestions for making standard SPT2 hold up to the weather?

(Next time i order wire, i guess i will get the good stuff from mcmaster carr.)

Thoughts?

I have brown indoor cords that I have been using outdoors at Christmas for over 10 years and haven't had to replace one yet. That includes 4 winters in Michigan.........

[lboucher]

I figured i would hear as much.
I mean its not like we are using the extension cord outside all year round.
The cord is only outside 2.5 months out of the year, and half of that time it is probably covered by snow.
While it goes against my better judgement, i want to put the burdon of proof on those that think useing SPT2 is a problem.

Anyone else have good long term experience.

Ref: Delmar's Standard Textbook of Electricity 4th Ed.
Ref: NEC Table 310.16


SP1 has 12 runs of a solid core, small guage wire
SP2 has 16 runs of a solid core, small guage wire
SP3 has 24 runs of a solid core, small guage wire
SP4 has 48 runs of a solid core, small guage wire

GaugE.....CM.....Max Chassis amps.....Max Wire Run Amps
22.....0642.....07.....0.9
20.....1022.....11.....1.5

16.....2583.....22 .....3.7

--CALCULATIONS--
R = resistance of the wire
K = ohms-cm per foot
L = Length of wire in feet
CM = circular mils (area of wire)

To find:
SIZE OF WIRE: CM = (KxL)/R
LENGTH L = (RxCM)/K
TYPE K = (RxCM)/L

Finally, as I'm only in my second year of this wonderfull hobby, I went to
someone who has it all figured out already: http://www.planetchristmas.com/WireSize.htm

Best of luck,
