Which jumper cables

[TVZ]

I need a new set of jumper cables. I'd like for them to be satisfactory for my MF 1726E as well as automobiles. I will get "heavy duty" ones, as I've had experiences where lighter cables did not do the job when needed.

As I understand, 4-gauge is considered "heavy duty", but 1-gauge is even better for "heavy-duty" equipment. I'm not sure what is meant by "heavy-duty equipment". Do you think that 4-gauge will be satisfactory in all situations for my tractor and automobiles? Or should I go with 1-gauge to be safe?

I used this comany for all my solar projects and have bought jumper cables from them.
High quality and fast shipping. They will build them how you want them. The twin cable they use has TPE insulation which resist abrasion and oil.

Finer 100% copper stranding so the cable remains flexible.

The reason for larger wire is to reduce voltage drop with distance. The length of the cables needs to be considered as well. The voltage drop in the cable is the product of the resistance of the cable multiplied by the current flowing at that time. Any resistance due to corrosion at the battery terminals or the wires attaching the clamp will also drop voltage. The condition of the batteries themselves can also limit current flow. This is really not a simple question but the generic answer would be bigger is generally better. Of course you can always build your own cables out of even bigger wire. Generally welding cable is more flexible than regular stranded cable.

I looked for cables a couple of years ago. Almost all I found in stores were aluminum with copper coating. Many stores had no all-copper jumper cables.

With its high level of electrical conductivity, as well as its heat-resistant properties, copper is commonly used to make wire. Most electrical wire, in fact, is made of copper. With that said, not all wire is made of solid copper. …

Any of the twin lead cable on this web site will make better booster cables then most you can buy.

Kind of OK, fairly good to real good, of course 25 feet at $5.86 a foot hurts a bit plus the cost of the 500-800 amp clamps to go with it. I like 25 ft cables for those times when you can't get to the front of a vehicle.

4 guage will be fine in my opinion. It is good for 140 amps from the NEC 317 tables for conductor ampacity in free air.

You do not need any larger than 2 gage cables. Four gage would do for most cases but 2 is better if you want "heavy duty." Length is an issue most of the times I have needed jumper cables and you need to evaluate what length you need. I would not consider less than 8 ft length and 12ft will be handy. I would not go longer than 12ft because of the voltage drop at high current levels in longer cables. Stay away from aluminum cable which is only a cost advantage and much of that is questionable with the seller being the beneficiary, not you. Whoever above suggested welder cable is right on. If you make up your own cables he is exactly correct that welder cable is a lot more flexible and is made to expect rough use. The clamps should not be taken for granted. Get heavier ones and pay attention to how they connect with the wires.

I had a very nice pair of jumper cables at one time but haven't been able to find them for a while now.

If you bought these clamps how do you attach them to the wire, do you need a special crimping tool?

I beleive that they are using an "open" ring terminal for the cable to lay in which can be closed up with repeated clamping with vise grips or in a vise. My preferred method if I don't have or can't find the right sized crimping tool is my vise (using it as a clamp) and I'll often lay a small pin punch in to get a good solid "crimp" I have also used my press but that is getting into a bit of over kill.
