crossing each other at an angle greater than 15 degrees) should attain the above 2'-0" minimum when feasible; however, physical constraints may reduce such separation to 1".
NOTE:
A minimum separation of 2'-0" must be maintained between N.I.S. conduit systems and i
fluorescent lighting fixtures and lighting l
system conduits except for conduits crossing at an angle of more than 15 degrees.
e.
Minimum separation between conduits containing powerj cables (Raceway functions 10, 20, 1G, 2G, 1K. 2K and SK) for a run of 10 ft. or more shalli not be less than the outside diameter (00) of the largest conduit.
Combinations exclusively between Non-1E and Non-1E functions (1K, 2K and SK) shall be addreissed to engineering on Figure 2 (Punch List) of Reference 1-A.
l f.
Minimum separation between a
conduit containing safety related cables and associated cables and the top of an open bottom tr->
having different train ling or channels shall be two (2) feet in cable i
spread room and three (3) feet in general plant j
area.
This separation may be reduced to four (4) inche:s when the tray has a solid cover. When the con-I duit above an open tray contains non-safety related cable, the minimum separation is one inch and no covers are required.
