I have a few questions on the bonding/grounding at a rectifier site. Here's what I have: 240v 1phase 3-wire drop from transformer to a disconnect. The 2 ungrounded conductors are fused and the grounded conductor lands on a bus bar in the disc. Then, 3-wires (2 black ungrounded & 1 white grounded) go to a rectifier, which is used for cathodic protection. . The 2 black wires land on a 2-pole bkr and the white wire lands on a terminal strip that is bonded to the enclosure. There is a ground rod connected to the rectifier enclosure and the enclosure and there is also 120v circuit being used in the rectifier enclosure. Is there code violations here?? I thought the ground rod and grounding electrode conductor as well as main bonding jumper should be in the first available disconnecting means and then a grounded conductor and egc are seperate from that point on. Can anyone please help me with this as this is the first part of my problem??
