Tinned Copper Earth Bars
Tinned Copper Earth Bars
(OP)
Hi,
Can someone please assist. Do we need to tin copper earth bars when bolting tinned copper cable lugs to it. I am working on a project where we have coflicting opinions. Some bars are in a substation and some on site for plant earthing. Project is in the UK.
Best regards

As long as the connections are dry, copper oxide should not form.
RE: Tinned Copper Earth Bars
I agree with you. I was refering to the oxide that often forms on the surface of the bars over time. Once a connection is bolted up, with clean surfaces, oxidation does not usually form in the connection. A corrosion inhibiter applied to the surfaces prior to bolting up is a good idea.
