Say I have an SDS transformer, feeding two sets of secondary conductors, each to separate disconnects as permitted by 240.21(C) and table 450.3(B) note 2. Typically, we can make the N-G bond for an SDS at either the transformer or the first disconnecting means. Then there is the exception allowing a bond on both ends for outdoor SDS's if there is no parallel path. But in this case, is it correct that there is no requirement to make the bond ONLY at the source of the SDS, despite the fact that a parallel path for neutral current between the two disconnect enclosures will be created if the bond is at the first disconnects?
