Discuss Earthing across flanges in the Industrial Electrician Talk area at ElectriciansForums.net
Why would you want to? don't the big bolts form a good enough connection? done any testing.With regards to electrical continuity across pipe flanges to bs 7671 I cannot find anything on how to size flat braided cable. Could someone point me in the right direction please is there a rule of thumb with regards to bolt size? Thanks
Not always,often the big bolts will do very little to aid continuity. The pipes are glass/resin or plastic coated with a non conductive gasket between flanges. Even older pipes are heavily painted and cant be relied on for decent continuity.Why would you want to? don't the big bolts form a good enough connection? done any testing.
