Hi all, I want a busbar with a particular shape to fit in a housing. It will be used to earth all shielded cables. Is there a particular copper grade for busbars? Will the bar in the link below do the job? http://www.ebay.co.uk/itm/COPPER-BA...UK_Crafts_Other_Crafts_EH&hash=item1c3fd8f301 Thanks in advance.
