Jeff,

ILSCO makes an inline waterproof splice that is rated for copper and
aluminum and UL listed. Whatever splice you use has to be direct burial
rated. Part number is USPA-350SS-DB.

Bill.

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.
