I just installed a 50 foot ug feeder to a 100 amp main breaker panel located in the tack room of a horsebarn in pvc conduit.It ran from a 200 amp comb.meter disconnect on the side of a house to the barn.I tappped[crimp conn.] the wires with the house conductors into the 200 amp breaker.The inspector said the barn panel exceeds tap rule.Where does 240.21[5] come in to play?Should I have installed a means of OCP off the 200amp disconnect before feeding the barn panel?
