Hi everyone,
We are building the service for an apartment building and are getting several different stories about where to bond the neutrals and grounds together. Here is the scenerio: CT cabinet with trough mounted directly to the side of it. 3 4" conduit runs to feed 3 400A disconnects. The neutrals all will land in the CT cabinet. The engineer is saying all neutrals and grounds (cold water, grounding electrodes, and grounds going to each 400A disco) should be bonded in the trough. Another theory is that the neutrals and grounds should be bonded in each disconnect. Does anyone know what the real deal is? Your input is appreciated.
