I have been confronted by a plans reviewer regarding gutter taps that I have never had a problem with before. They are stating that gutter taps are only allowed for AIC ratings of 10,000 or less as the actual insulated multitap or insulated gutter tap is not rated above that. We have typically been utilizing gutter taped panels in building risers so there is only one riser feeding a panel on each floor. The reviewer is referencing NEC 90.7 and the UL white book. He has also contacted Burndy and they supposedly reinforce his position. Has anyone ever run into this, or even heard of this?
