TEMCo INDUSTRIAL WC0455-40' (20' Blk, 20' Red) 2 Gauge AWG Welding Lead & Car Battery Cable Copper Wire Black + RED | Made in USA

They sell multi-strand thick gauge at the big hardware stores, but if you get 2 or 4 gauge you're looking at a core of 10-20 strands of thick solid line- very hard to shape and pull, especially in tight spaces. After wasting some money on that (although my alternator did run, so I guess it was worth it) I coughed up the cash to get this stuff. I am so glad I did. Redid my alternator, grounding, and starter wiring, including pulling the starter across the vehicle deep in the engine bay. Strung up a dual battery, solar, inverter setup (inverter runs through the firewall to the truck bed). The flexibility of this cable is what made the intricate and tight-fitting design possible.

Having worked with high amperage systems during my career, I'm experienced in the selection of the type of wire and insulation necessary to safely handle lethal current.I've NEVER seen better conductor. We're not talking 12 gauge automotive wire; This is 4/0 fine braid copper used in welding lead, or high amperage ac/dc systems. All this quality in a very flexible jacket at incredibly low prices.I installed it in a class "a" motorhome with 450 amps of solar connected to an 800 amp battery bank, that needed to carry power to the load center 26 feet away without any line drop.Mission accomplished. Best system I ever wired!

Pro's:* Works great* Flexible, durable, soft insulation* low resistance* heavy dutyCons:* Smelly out of the package/ needs to air outSo far the wire has been great. I'm using it for a portable solar setup, and I'm getting much better amps/ total watts than I was with the smaller AWG wire I had on hand.The wire is pretty flexible, and the insulation is soft enough to cut easily, and strip, with the copper wire being thick enough that I don't lose any strands.The seller was also very helpful when USPS lost my package, and fixed the situation quickly.They also have a really great warranty on their products, and appear to want to offer high quality products and customer service.They don't have any UV rating, so I'll update if the insulation starts degrading over time, but so far still like brand new (but without that plastic smell)

I priced this $85 against 2 other vendors who wanted $125 for the same length of identical 4/0. I ordered 1 run just to compare to the 2 other vendors (I buy a lot of 4/0) Sure enough it’s identical. So I bought another run. The photo is of this brand next to another brand costing $40+ more for 20-25 feet

The 4 Awg and 2Awg cables came highly recommended and were every bit as good as I hoped they would be. I ended up using the 4 AWG wire and expect it to last a long time. The cable is very flexible, heat resistant and looks and feels high quality. Easy to crimp and easy to maneuver through tight spaces in a vehicle. With some loom and/or split tubing, the cable should last at least as long as your vehicle. There are certainly cheaper cables available on Amazon and elsewhere but I would recommend getting the highest quality cable one can lay their hands on.

I'm installing a high current charging system so I can recharge my RV (trailer) batteries from the tow vehicle (2018 Sierra) when needed. I wanted high strand count welding cable due to its flexible properties. This cable is made in the USA, rated for high current and comes in both red & black color for easy identification. This is exactly what I wanted at a substantial discount compared to my local welding supply shop. In addition, the local welding shop only carries "black" so the red and black wire provided by TEMCo is a definite improvement.

Made in the USA! You can actually go to the manufacturer's website and check out the pride they put into their materials and work.I've learned a lot about battery cables in the past 6 months, and while I've settled with CCA (copper clad aluminum) in the past when buying from the box stores, I've evolved to using pure copper cables or OFC (oxygen free copper) if I can find it and then using quality lugs that I can crimp on myself. This gives me increased quality control on my projects and helps provide that clean, custom look I've been chasing for years Of course improved performance and reliability don't hurt either.Follow up your quality cable and lug connections with good double or triple walled heat shrink and you'll be on the path to understanding life!This cable is a great compromise between that cheap crap you can buy off the peg at (insert store name here) that's usually too long because one size fits all and that ridiculously priced premium audio cable that you shouldn't have bought.In short, it's a no-brainer to use this stuff.

For car stereos of about 2,000 watts and up, start by upgrading to a custom high output alternator for your vehicle, usually 250-370 amps, whatever is the max possible for your model. Then, buy approximately 25' of this exact welding cable for the "Big 3 upgrade". No capacitor needed or recommended at this point. Match up the best 4 channel amplifier and component speakers with your desired mono amp and subs and you are in business. This 4/0 gauge is even better than the 1/0 for staying cooler on the inside. Just some advice based on my own trial and error. Good luck and this is the best wire you can get for a high-powered sound system!

Wow, super fast shipping! Great cable, incredibly flexible & true 4 gauge! The rubber jacket has a soft feel like silicone tubing, yet is very tough & durable. This IS NOT the cheap, under-sized stuff available everywhere else...this is very high quality, 4 gauge cable. Bought for dual battery setup on a Side x Side...definitely going to order more!

The cable is not very good quality. The plastic coating is soft and very vulnerable to damage. The inner copper looks inadequate. I've seen domestic cabling used to support 10A with more copper and better quality. I'd steer clear of this people.

Great deal for a pure copper high strand count wire.

works great thanks

Used for my winch was the perfect length to reach from my battery to my back hitch on my truck
