I am a little confused about the very first row of the table. " In fabricated ducts". The table indicates N for everything except OFNP & OFCP.
It appears that the table is allowing installation of OFNP & OFCP in fabricated ducts without a metal raceway, however the column to the left
states " In fabricated ducts as described in 300.22(B)" that requires a metal raceway for everything. If this is the case, then why is the first row separated from the second row "In metal raceway that complies with 300.22(B)?
