Aluminium lug to Copper bus bar connection

I don't know about the rest of the world, but here in New York we are required to use 'Noalox' or the equivilent between Al and Cu connections. It's an impregnated grease that you can use under the lug to prevent arcing betweeen the different metals.

Thank you for the comments. We will try it out.

hi yaar, a paste is available in the market which can solve ur prob. all you need to do is apply the paste in such a way that it remains at the contact point of two diffrent metal. byee

i agree with you : i might consider changing the al to cu connection to the end of the cable.. thus making the bus bar connection similar metal.. moving ANY chance of failure to an easier access point to repair or replace.. much rather replace the connector than replace the bus bar

An anti-oxidant and anti-seizing compound improves efficiency and service life of aluminum electrical applications. It typically has suspended zinc particles that penetrate and cut oxidation of aluminum and provides additional inner-strand and inner-conductor current paths for improved conductivity and cooler connections in cable splices. The carrier material excludes air and moisture to prevent further oxidation and electrolysis of the metal contact points.

It is for use with all types of pressure-type wire connectors including screw-on, tap, service entrance and split-bolt. It reduces galling and seizing on aluminum conduit joints and promotes good ground continuity.

Arcing is a different issue - loose connection.

In aircraft power systems weight reduction and copper costs pushed for use of lighter larger gauge aluminum cable for the runs and spliced them to the original design copper cable and connectors. Intalling the splices and applying their messy sealants and thermoplastic tubing with thermoplastic adhesive inside, etc ,etc, was a critical multi-step process. A molecule couldnt get in after that.

the always friendly prc - 1422 series ?... a little heat shrink ..?; good to go?

PRC - 1422 Nope, Thats for fuel tanks.
