Cu to Al Splicing [RE-wrenches]

[Jeff Clearwater]

<x-flowed>

Hi Travis,

Yes I'm familiar with the Polaris and Burndies etc. - use them all 
the time.  Basically the same as what I described but more expensive. 
They are basically a dual rated (Cu/AL) butt connector with 
insulation and anti-corrosives in them.

What I was looking for was any ways that folks use to ensure no 
corrosion even with these dual rated connectors.

Thanks!

Jeff C.
