I need to run 14-2 UF-B from the panel to outdoor lighting. The cable run will go up a concrete block wall, across engineered trusses and down another concrete block wall before exiting through a conduit embedded in the building slab. Options for the block walls appear to include running the UF-B through Sch. 40 conduit or stapling it to a 2x4 mounted to the wall. Do both of these methods meet NEC requirements?
Options for the trusses appear to include stapling to the truss face when running with the trusses but a 2x4 needs to be installed for crossing trusses. Is that correct or can I simply staple to the bottom of the trusses whether the run is parallel to the trusses or crossing them?
Thanks for your help.
