So we arrive to determine why a customers generator continues to blow fuses in the transfer switch. We find the following "installation" of a transfer switch. See pic. So we un-bond the neutral bar, separate the grounded and grounding conductors and correct a slew of additional issues. Underground damage to the conduit and conductors was the actual culprit.
My question however is this. Going by the tap rule 240.21 B 1, the 100 amp SER cable tapped on to the 200 AMP SER cable, fed some 25 ft away from a combination 200 OCPD / meter base, is not in a raceway between the TS and sub panel. So even though it was inspected (lol), it's in violation and needs to be corrected.
But, for the tap rule to apply, is there a max distance or insight rule from the feeder OCP that the tap can installed?
