From the nations leading manufactures

Carol Wire and Cable
Coleman Cable
American Insulated Wire
General Cable & Wire

We purchase Factory Remnents, and Surplus Overruns and pass the saving on to our customers. At National Supply we specialize in portable cable and wire including SO, SOW, SOW-A, SEOW, SEOW-A, Entertainment Cable, and Type W. Single and Multi Conductor Cables.
We are often asked how we can sell electrical wire at these very, low prices. rest assured all the wire we sell is brand new first quality and 100 percent gauranteed.

Randoms, Remnents or Shorts

Randoms are lenghts of wire to short to make a standard "Put-up".

Put-ups

Put-upsrefur to a standart carten or spool length. Standart put-ups vary in length depending on the product and manufacturer, 250 Ft. 500 Ft. & 1000 Ft. are most common.

Surplus Electrical Wire or Cable

Surplus is an industry term used in the wire and cable manufacturing industry to describe any wire that needs to be liquidated, the reasons can vary. The factory may have had an Overrun.

Factory Overrun

An Overrun can be the left Over material from a custom print.

Cosmetic Imperfections

Cosmetic Imperfectionsmay be a small blemish in the oter jacket, misprinted wire, wire printed using the wrong color ink, sometimes wire that has been double printed. Dirty or even dusty wire will be tagged as surplus, simply because it can no longer be sold as new. The exception would be any printing that would misrepresent the product in any way.

Overstocked Wire

Often times the manufacturer is simply just clearing out the old to make room for the new.

Wire & Cable Liquidators

We are simply liquidators, a clearinghouse for surplus & overstocked electrical wire and cable.

Gaurantee

We Guarantee the quality is equivelant of New because that is exactly what it is. The only real differance is we are able to sell wire well below wholesale prices.

New VS Used

We only sell brand new electrical wire!
We do not sell any wire or cable that has been used or energised!

Industry Terms & Definitions

AWG - Abbreviation for American Wire Gauge. The first number in the product description (e.g.,12/3)

S - Heavy duty, rubber-insulated portable cord. Standard copper conductors with separator and individual rubber insulation. Two or more color-coded conductors cabled with filler, wrapped with separator and rubber jacketed overall 600V.

SEO - Same construction as STO, except insulation and jacket are made of Thermoplastic Elastomer Rubber (TPE) 600V.

SEOW - Same construction as SEO, except suitable for outdoor use. Usually UL listed for continuous submersion in water 600V.

SJ - Junior hard service rubber-insulated pendant or portable cord. Same construction as SJT except insulation and jacket is thermoset 300V.

SJEOW - Same construction as SEOW except 300 volt rated.

SEOOW -Same construction as SEOW, but inner conductor insulation as well as the outer jacket is oil resistant.

SJO - Same as SJ, but oil-resistant outer jacket. Can also be made "water resistant." 300V, 60°C, 75°C or 90°C or 105°C.

SJOOW - Same as SOOW except 300 volt rated.

SLC - Stage Lighting Cable. A 600 volt single conductor cable for use with indoor and outdoor stages, fairs and carnivals.

SO - Hard service cord. Same construction as type S, except oil-resistant jacket. 600V, 60°C to 105°C.

SOW - Same as SO except suitable for outdoor use.

SOOW - Same as SOW but inner conductor insulation as well as the outer jacket is oil resistant.

Water Resistant - UL designation for cords that have an insulation on the individual conductors that passes UL requirements (e.g., ST Water Resistant or ST Dry 105°C, Water Resistant 60°C).

W - CSA Weather and Water resistant Designation for outdoor listed flexible cord that is tested against sunlight requirements (e.g., SOW, SEOW)**.

**Do not confuse this with the mining cable Type "W" which refers to "without ground," such as 4/0-3 W.

W (Type) - An industry designation for a 2kV portable power cable consisting of 1 - 6 insulated conductors. For use in mines and similar severe duty applications. MSHA - Is an agency of the US department of labor Mine Safety Health Administration

Gauge / Conductor

The first number refers to the wire gauge, the following number refers to the number of conductors.
Example 12/3 the first number 12 is the gauge and the second number 3 is the number of conductors.

Portable Cord Letters and Connotations

S = 600 Volt Service Cord (First recognized by UL)

J = Junior Service - 300 Volt

T = Thermoplastic

E = Elastomer (Looks and feels like rubber, but is actually a thermoplastic)

O = Oil Resistant Outer Jacket

OO = Oil Resistant Outer Jacket and Oil Resistant Insulation

W-A = Weather Approved(e.g., SEOW-A)

"W" or "Type W"

"W" is conciderably lighter, easyer to work with and much less expensive to purchase than "Type W". On the other hand Type W is more crush resistant, will tollerate much more abuse and is capable of carrying more current.

Am I required to use a Type W ? Check with your local inspection department to be certain! Unfortunatly there seems to be alot of mis-information about what is required in the carnival or entertainment industry. We believe this stems from an article published in an amusement magizine. The article states that "all" wire used on carnival midways must be Type W. We questioned the auther about this statement, he explained to me that any "W" type wire would be accetable including sow and seow in addition to "Type W" I was hoping after our conversation a follow up article better clairifying what he ment to say, and what he did say would be published. No follow up article was ever published.

We are not making any recomendation one way or the other, we are mearly pointing out that we have seen alot of confusion in this industry as to the meaning and code requirements of these two almost identacle industry terms. Any state, county or even munisapality can enforce it's own set of rules. It is up to you to make sure you are in compliance. The codes are always changing what may be exceptable today may not be tomarrow. I hope this has been helpfull, if you have any questions or comments on this subject please bring them to my attention.

SEOOW or SOOW the choice is yours

	SEOOW	SOOW
Temperature Rating	-50 c to 105 c	-40 to 90 c
Jacket tensile strength (PSI)	2200	1411
Abrasion Resistance	1900	800
Weight	15% Lighter	-----

The results are compairing coleman cable seoprene 105 SEOOW black to thermoset SOOW black.

What Exactly is Elastomer ?

"A class of long-chain polymers capable of being crosslinked to produce elastic compounds, e.g. polychloroprene and ethylene propylene rubber."

"A material which at room temperature stretches under low stress to at least twice its length and snaps back to original length upon release of stress."

"A material that exhibits very low or zero crystallinity and a high degree of flexibility."

SEOW has been evolving ever since it's conception. SEOW is noticably lighter and easyer to work with than SOW and stays cleaner longer. Most people who have used SEOW seems to prefur it over SOW or at least equally as well. There is still some skepticism among those who have not used SEOW before because the jacket is smooth and shiny, resembelling a plastic type material giving the illusion of inferior quality.

We stock both types of wire, if you have a preferance please let us know.
