Nbcs Mike Tirico Explains Why He Exited Kentucky Derby Coverage Severe Nut Allergy What Happened To ? Sports Host Leaves Early Over
A conductor installed on the supply side of a service or within a service equipment enclo‐ sure (s), or for a separately derived system, that. A switch board will be used instead of a panelboard. I'm planning an installation similar to the image attached.

Primary is supplied by utility, but the transformer is customer owned. Why does the nce requires this separate ssbj, rather than permitting bonding the transformer case to the secondary grounded conductor? Ssbj is bonded to both the transformer enclosure and the mdp enclosure (not sure exactly where).
Also Read:
The ssbj in each raceway is sized according to the conductors in each raceway.
Ssbj, sized per 250.102 (c) is run with the secondary a, b, c, n. So convert your parallel conductors to a single conductor and look the size up in the table. I understand sbj is where you bond your secondary neutral to ground. How come the ground fault at the load (that will pass through the egc [then] the ssbj [then] the system bonding jumper to return to the source), needs a 700 kcmil [that].
The ssbj would be in parallel with the neutral if you installed an sbj in both transformer and first diconnect enclosures. But that is not permitted, even by the exception. The grounding conductor is actually a ssbj (supply side bonding jumper) and for a transformer secondary it can be sized according to the size of the ungrounded conductors in. So i am trying to understand the different terminology for all the bonding jumpers.
