Sorry if this has been discussed before, I could not find anything.
My question deals with bonding requirements of flexible metal conduit going from the secondary side of the transformer to the disconnecting means. It seems that the different inspectors here have varying interpretations of how that should be done. Some require bonding on both ends, some on just one end, and others not at all.
Really, the only code reference I can cite for this is the requirement for an Effective Ground Fault Current Path in 250.4(A)(5), but that of course is totally up to interpretation as to what is effective or not.
Personally, I think bonding one end or the other would be sufficient.
Does anyone else have some ideas about this?
