Best way to connect 6ga wire to buss bar?

Zero Cool · 2nd January 2007, 06:03 AM

What is the best way to connect some solid copper 6 gauge wire to some copper buss bars? I am looking for the best attachement method. IR lowest resistance. most solid connection etc.

How do that connect wires in big transformers?

Hydro here uses these types of clamps frequently.

Big crimp on terminals.

Guess i am going to have to fabricate some sort of clamping mechanism or find some really big crimp on lugs and the tool to crimp them.

Go to the hardware store and buy a "ground lug".

So a ground lug is the best, lowest resistance, way to connect a 6ga wire to a copper buss bar?

Seems so archaic.

The advantage of mechanical clamping is that if the wire is overloaded and heats up, solder joints won't melt. You could also drop into an automotive store and pick up some battery cable ring terminators. When I have to do work like that, I usually go to my neighborhood West Marine. They'll tag you an extra buck for the terminator but they have a swaging machine for the crimp connection. You can't do 6 Ga. very well in a set of channel lock pliers.

After the mechanical swage, I'll usually throw a torch on the connector and fill with solder... but never just solder for the reason mentioned above.

People underestimate how easily wires desolder themselves.....

wanna clean the solder off some component leads? Just keep em over a lighter flame for a few seconds and tap em against the counter, then wipe them off...

Oh i would have never suggested soldering alone. Yes i have seen weak mechanical connections that have been soldered heat up and melt the solder out!

I just wanst sure if there was some better means that i was un aware of, or a particular brand of crimp that is best for solid wire etc.

I once saw some cables that had been compressed and RF welded to a crimp lug. now that was cool. bet that equipment is expensive!
