My colleague and I have been in a quandry about an installation that we were confronted with.
There is a 200 A main service panel with a 100 A panel next to it. The two panels are connected with steel conduit, about 6" apart.
The second panel (I am purposely not useing the term sub here) is fed from a 100A breaker from the main, #2 AL wire and also has a #3 copper to the neutral bar, as well as #6 Cu to the ground bar. It has a bare #6 going outside to earth ground as well.
Here's where it gets tricky -- the neutral and ground are bonded in the second panel and the neutral and ground wires are randomly attached.
There are no feed through lugs on the main panel.
So -- can a panel which meets distance and wire protection requirements for a tap through be wired in this manner? It seems like the second panel meets all the requirements of a tap through installation, except for the use of a breaker in the main panel as the feed.
Maybe I don't get it. I have read about this in great detail. I am mostly in carpentry so you can fairly tell me to get an electriction, but unfortunately, we are getting different opinoins from them as well.
This is my first post -- I've been a reader here for years though and really appreciate all the sound discussions that I have read. Thanks in advance....
