Heavy gauge cable splicing

[kroberts]

I have to splice two heavy power cables together. Given that the cable is in a bimmer, the AWG gauge numbers dont actually apply. The cable would be between 1 and 0 gauge, actual diameter is about .305. I dont have access to a hydraulic swedger or anything like that. I'm pretty good at soldering normal wires but if there was a method for soldering cables, I'm sure I couldn't do it!

Any sparkies out there have any suggestions?

TIA,

Get a split bolt connector. Electricians use this for doing this exact type of splicing. A split bolt connector is essentially a normal looking bolt with a slit down the middle of it. You stick both wires into oppposite sides of the split and then tighten down the nut.

Secondly, you can get a 1/2 inch butt splice that is a short tube of metal with set screws on the side of it so you simply shove your wires in at both ends, tighten up the screws and then cover it with tape or heat shrink.

JScotty,

Where do I find these lifesavers? Are they automotive, industrial, or residential items?

Either sounds perfect.

Thanks

Those (and you want the copper ones) are available at any electrical supply house.

An alternative is a soldered on sleeve and heat shrink tubing. But for that you'll need at least a MAPP gas torch. A better heat source is a oxy-acetelene rig with a small tip.

Split bolt connectors can be found at home depot or any place that sells residential or commercial electric supplies. Its a very common thing. And as jlevie suggested, make sure you get one that is made of copper. Other types will work just fine but you will need to get a tube of OX Guard grease to prevent the corrosion as a result of the mis-matched metals.

Went to Lowes this morning and bought a Mechanical Lug. It looks like it will work.

Thanks,

C- crimp and tool will give you best splice. Tool you will have to rent. Like the name, it’s a c shaped piece of copper that crimps down on you two lines. This can be found at any major electrical store.
