Metal boxes, that have a #8 bond wire running to a niche, and that niche is bonded to rebar, are already bonded. No additional bond is required on the j-box outside lug.
Typically a junction box either contains splices on the energized conductors (thus requiring that the box be individually bonded with a pigtail connected to the EGC), or the box is simply a pull-through point (thus not requiring the box to be bonded individually with a pigtail).Anode Junction Box for Cathodic Protection . Farwest standard anode junction boxes provide a low-cost solution to consolidate multiple impressed current anode cables and a means for monitoring individual anode currents. Build to last, these junction boxes include a Hoffman powder coated steel enclosure, a Micarta insulating panel, copper buss bar, shunts (customer . The outlets in the garage have metal junction boxes, fed by metal conduit containing two wires (hot and neutral). There is almost no voltage difference between the neutral wire and the metal box; how can I tell if the box is truly grounded, and not just tied to a common wire somewhere inside the wall? .
