this bussed gutter without a disconnect ahead of it doesn't seem like it is legal. 3-Φ power comes from a small meter can into a ct can and then out the back of the ct can through the wall into the warehouse where it enters a gutter with busses. then it goes to the separate disconnect boxes. is it legal to go into this bussed gutter before a service disconnect? it looks unsafe because someone could get into the gutter and it is unfused inside the building. i couldn't find anything in the code except allowing taps, but in 240.2, "a tap conductor is defined as a conductor, other than a service conductor, that has overcurrent protection ahead of its point of supply that exceeds the value permitted for similar conductors.." so how is this allowed?
