Copper to Aluminum

I was always told that the chemical reaction will not travel upward towards the aluminum conductor if the AL is on top. But, if the CU is on the top, then the stuff will leak down all over the place no matter how much inhibitor is being used.

we must have been typin at the same time 639 At least maybe that proves we were on the same track

GREAT MINDS THINK ALIKE

Cool, thanks for the info!

my old man always told me " A over C" Aluminum over Copper. "A over C" is just a easy way to rememebr it, A comes before C so thats a easy way for me to remember it.

I'm a A over C man also. The main reason for corosion is disimiliar metals with no inhibitor. Continual problems are a result of not cleaning the conductor. "Copperweld is a must clean ,and not only when it's green." I tend to favor fargoes versus other one bolts, or sqeeze-ons. At the secondary if you think you have found the offending connection.... clean behind it {house side} both wires, and put your knife across them and see if the lights get brighter. I would suggest using the knife backside as ,Im terrible at knife sharpening to get little knicks filed out. Just a heads up ,as I had to learn these the hard way . At the weatherhead look for some melting of the insulation.... the cause .... a loose connection, or bad connection. Be safe, 1 Electro-man

OR........
IF YOU SUSPECTA NEUTRAL PROBLEM....PUT YOUR CLAMP ON AMMETER ON THE GRD WIRE, BETWEEN THE METER CAN, AND GRD ROD------------ANY AMPERAGE WILL BE WHERE IT IS TRYING TO FIND A RETURN PATH--AKA GROUND/NEUTRAL...............OR JUST USE THE 'SUPER BEAST'---IT PLACESA LOAD ON THE CONDUCTORS, AND TELLS YOU REAL QUICK IF THE PROBLEM IS THE CUSTOMERS, OR THE UTILITY

I HAVE USED IT TO TRACK DOWN A BAD SECONDARY NEUTRAL CONNECTION (A-C)---3 SPANS FROM THE METER LOOP
