ECN Forum Forums Photo Discussion Forums Violation Photo Forum Old GEC Method (1960's?)

These pics were provided by Ian, "theelectrickid." I am told that this is a typical GEC arrangement from "Leavitt town" homes of the 60's.

First, a bare aluminum wire exits the panel:





Then, under the kitchen sink, the wire terminates at a cold water pipe:




As I understand it, there is no ground rod.


I have a few issues with this method. Perhaps the first one is suggested by the corroded clamp on the pipe, above the one being used .... aluminum wire + brass connector/ pipe = corrosion.

Any thoughts?
