Swivel joints may not give metal to metal connection. For these it must be verified that the electrical contact resistance is consistently less than 1 MƒÇƒ|ƒnNormally the resistance across a swivel joint is low enough (a few kƒÇ) but some greases can be highly insulating and electrical continuity across swivel joints needs to be checked. Checks should be done for several positions of each joint because the resistance can vary. If continuity over a swivel joint is inadequate, the resistance can be reduced by changing to a more conductive grease or by providing a bonding link across the joint.
