Where to Put the N-G Bond

Supply Side Bonding

Supply Side Bonding

The raceway from the transformer to the panel is not and does not contain an EGC. No mater where the supply side bonding jumper is installed, you need a supply side bonding jumper between the transformer and the panel. The SSBJ can be a non-flexible metallic raceway or a wire.
In either case the EGCs originate in the panel with their associated circuit conductors.

Don,
Thanks for defining EGC 'origin' at the equipment panel differentiation from the Supply Side 2014 NEC 250.102 vs 250.122 EGC bondings. Table 250.102(C)(1) delineates the system conductor sizing of the bonding jumper. rbj
