    CQD 9/23/22

    Hello Code Friends, 250.30C states if the Separately Derived System (SDS) is located outside, the grounding electrode connection shall be made at the source location. If the SDS (customer-owned transformer) is located outside, does it matter if the system bonding jumper is installed at the transformer or the main bonding jumper is made at the first disconnecting means?

    Thank you,
