3 Types of Electrical Cables With THHN Wires
When 3 electrical cables all use the same THHN wire conductors what sets them apart? The amount of protection in the overall jacket.
1. Romex® Cable
Romex® cable uses THHN wires and an overall PVC jacket rated for indoor use only. The thin PVC jacket is designed to be cost effective rather than a universal cable that can be used indoors and outdoors. The jacket wraps the conductors together for ease of installation rather than protection.
2. MC Cable
MC Cable, or metal clad cable, is used indoors without conduit. The aluminum armor jacket acts as conduit so that you don’t have to buy Romex® cable and conduit for the same installation. MC cable also uses a green THHN insulated electrical wire for a ground instead of a bare copper ground which allows it to be used outdoors.
3. UFB Cable
UFB cable offers the most protection with a strong PVC jacket the covers each THHN wire individually. As you can see in the picture each electrical wire is secure in its position and it looks difficult to damage. UF stands for Underground Feeder because it can be used outdoors and directly in the ground.
How to Trade Excess Electrical Wire for Cash
Save All of Your Electrical Wire
Make sure you save all of your copper electrical wire so that you can turn the excess into cash. Copper is worth a lot of money right now, $3.30/lb to be exact (Oct. 2013). A metal scrap yard will offer you about $2.80/lb of pure copper because they need to melt the insulation off and sell the copper for a profit. Saving copper wire is like saving change because it adds up quicker than you think.
Metal Scrap Yards
In order to get cash for your copper you will need to bring it to the nearest metal scrap yard. They will weigh it and let you know the going rate for the type of copper you have. THHN building wire for instance, will get you a higher rate of return than an extension cord. Extension cords use very thin strands of copper and an expensive rubber jacket to make them more flexible. Those hurt your chances of getting $2.80/lb for the copper weight because of the additional work the scrap yard needs to do.
Cold hard CASH is what you will receive when you bring your excess electrical wire to the scrap yard. They don’t give checks or receipts which make it an attractive method for thieves to steal wire and turn it into cash.
Just remember to save your excess electrical wire in a safe place. Telling people what you’re up to is like telling people where you stash your money away. I suggest trading it for cash whenever you reach 50-100 pounds because it’s worth in the area of $150 to $300.
Electrical Wire Scam
Copper is worth money, therefore copper wire is worth money. Did you know that the walls of your home are filled with expensive copper wire that thieves want to get their hands on? Do you know what they do with it once they steal it from you?
Difficult to Trace
When a thief steals copper wire from a home or building they bring it directly to a scrap yard. This is similar to bringing old jewelry to “Cash for Gold” locations in order to get CASH for your jewels. If you’ve never been to a scrap yard just imagine a junk yard because the look of both are fairly close.
A scrap yard isn’t the type of place that gives you great customer service and a receipt for your transaction. They’re the type that take any copper from any person at any time and melt it down immediately so that there isn’t a trace of it at all.
Electrical Wire Scam
1. Steal credit cards
2. Purchase copper electrical wire online
3. Bring it to the scrap yard
4. Run away
The funny part here is that the police cannot, and will not, track down the culprit. There are too many jurisdiction issues for them to catch the criminal. The situation ends up in an argument between the supplier of electrical wire and the credit card company because the individual who’s card was stolen won’t be paying the bill.
Avoiding the Scam as a Supplier
1. First Flag: Suppliers should make sure to check the shipping address of the credit card before shipping the electrical wire. 2. Second Flag: Check the sale price of the wire. Typically, these “individuals” purchase online so that they don’t have to talk to anyone in person. If you’re smiling because you made great profit on a large order it’s probably too good to be true. 3. You should call and have a conversation with the person to be sure that it’s a legitimate purchase. Ask them a few questions to feel out what they’re doing with it and let them know you have to ship it to the same address that’s on the credit card.
I hope everyone avoids these scammers! They’re everywhere!
3 Stranding Options for Electrical Wire
1. Solid Copper
Solid copper stranding means that there is a single strand of copper acting as the conductor. Common sizes of THHN wire that use solid stranding are 14, 12 and 10 AWG. NMB and UFB cable also use solid stranding for the 14, 12 and 10 AWG cables.
Contractors, electricians and installers use these sizes of electrical wire in homes and buildings. They want the cables to be stiff instead of flexible so that they hold their form during installation. An extension cord on the other hand, is manufactured very flexible so that the user can handle it easier on a daily basis.
Stranded wires use multiple smaller AWG’s and wind them together to get the same diameter as a solid strand would be. For instance, instead of using a single 10 AWG solid strand of copper one could also get a 10 AWG wire with 19 strands. Obviously those 19 strands are not all 10 AWG or it would be much larger in diameter. The math is calculated to determine what size is needed for 19 strands to equal 1 strand of 10 AWG copper. That way, both diameters of copper, solid or stranded, both exert the same amount of current.
3. Flexible Stranding
Typically, electrical wire used in homes or buildings does not come in a flexible option because the cables are installed and never touched again. However, extension cords and power cables are uncoiled to be used for the day and the coiled back on to the reel for later use. Generators cables and welding cable come to mind as flexible cables with very thin stranding.
If you need a flexible cable we can most definitely upgrade your electrical wire to a power cable. Just remember that power cables have a lot of design involved in them for outdoor wear and tear that feed into the price such as flexible stranding and thick rubber insulation.
5 Types of Electrical Wire
1. Indoor NMB cable or Romex® 12/2 cable
NMB stands for Non-Metallic because it has a PVC jacket instead of a metal clad jacket. It is a basic indoor electrical wire used to deliver power from an electrical box to lights, outlets and appliances. It cannot be used outdoors because the jacket is not prepared to handle the wear and tear.
2. MC 12/2 Electrical Wire
MC stands for Metal Clad due to the interlocked armor surrounding the THHN wires. The aluminum armor also acts as conduit when used for indoor applications. Many times NMB electrical wire is required to be installed within conduit for indoor applications, but now MC cable can act as the electrical wire and conduit in one.
3. UFB 12/2 Electrical Wire
UFB stands for underground feeder because it has the added protection to allow it to be buried in the ground without any additional conduit, raceway or tray. There is a slightly higher cost for UFB because it has more to offer than NMB cable and MC cable.
4. Tray 12/2 Electrical Wire
Tray cable is also a direct burial cable like UFB cable. However, UFB cable is “flat” which means each conductor lies next to each other as if they were lying on the floor next to one another. Tray cable is round which means the wires are slightly twisted together with the jacket surrounding them. Tray and UFB have slightly different applications so be sure to discuss each situation with your supplier or electrician first.
5. PLTC 12/2 Electrical Wire
PLTC stands for Power Limited Tray Cable. Power Limited means 300 volts instead of 600 volts. Simply saying “tray cable” will call out 600 volts. PLTC electrical wire is commonly used for electronic applications rather than electrical, but they have very similar attributes when compared to each other.
As you can see there are slight differences between each type of electrical wire. Putting the wrong type of wire in the wrong application could cause many problems such as a jacket that got eaten away too soon, too much voltage travelling through the cable or even that you paid too much for your product because you didn’t understand enough about the cable characteristics.
5 Ways to Get Rid of Copper Electrical Wire
If you have excess copper electrical wire you can get money for it easier than you think. Take a look at 5 different ways of turning your copper wire into cash:
1. Copper Scrap Yard
You can bring your excess electrical wire to a copper scrap yard and receive about 70% of the current copper rate. If copper is at $3.50/lb you will get about $2.45/lb of copper you have. Also bear in mind that they will give you a lower rate when you have a lot of insulation covering the copper. They’re interested in the pure copper and that it. The insulation creates more work for the scrap yard because they need to burn it off before melting the copper down.
eBay is always a great place to get rid of any product you don’t need. Make sure you check the scrap yard price first, then try to get a little bit more than that on eBay. You have a fully functional electrical wire that someone can buy for a discounted price. You should be able to get more than the scrap amount of it’s not going to be worth it for you.
When you put your electrical wire on eBay you should also include it on Craigslist and Amazon if you have the accounts. Some people like to use eBay, some like Craigslist and some like Amazon. If you want more people to see your wire you can’t just expect them to visit all 3 websites. Be proactive if you really want top dollar for your wire.
You can call a few electrical contractors, electricians or installers in your area to see if they need your length of wire. Be sure to offer them a price that’s a bit higher than the scrap amount but lower than the online retail price. The contractor will be happy that they got a discount and you’ll be happy that you made more money than scrapping it.
5. Your Supplier
Many times you can call the supplier that you bought it from to return it for cash. They will accept the electrical wire if it’s still in good condition but they may not give you as much as the scrap yard. Many suppliers like to also sell high quality products rather than returned items so they will accept the return and scrap it themselves. They aren’t necessarily trying to make money on the transaction but they want to make you happy without then selling a returned item to another customer.
