1/4 inch heavy duty power lug

[jmw]

Hello,
Hopefully as a non sailor, I will not offend anyone here by asking an electrical related question. I know that Sailors must do things in the correct, competent manner when it comes to making electrical connections!
I have high quality tinned copper wire (1/0 gauge) from the positive battery terminal.....that I am attempting to connect to a 6 mm alternator output stud......I would like to use an ftz heavy duty power lug (1 gauge) 1/4 hole.......
Considering the fact that 1/4 inch = 6.35 mm -- will a 1/4 lug make an adequate electrical (in terms of resistance) connection with a 6 mm copper terminal stud?
THANK YOU!!!

should do just fine, I would make sure that it is clean and use a lock/star washer to keep it from loosening....

I'm no expert, but I don't think you need that heavy gauge wire for just the alternator.

Thank you!
It is what is recommended for a Big Three Upgrade....with a high amp winch, AM lights and stereo.....it is recommended that Alternator Wire to Battery, Engine to Chassis, Chassis to Body, Body to Battery Ground Wires, etc......be upgraded...

That wire would mainly be sized for the output of the alternator, plus some safety factor. My AO goes to the starter, then to the batteries.
