Let's assume you have a separately derived system consisting of a transformer in it's own enclosure and a disconnect(or overcurrent) device in a separate enclosure. You have two jumpers. One from the transformer neutral to it's own enclosure and the other from the transformer neutral through any connecting conduit to the disconnect/overcurrent enclosure and then connected to the equipment grounding terminal bar. Which of these is the system bonding jumper?
