Garage - Protecting Wiring Installation

eastment

Hi all, new to this forum, first post.

Background:
I live in Colorado, North of Denver. I'm building a garage/barn (pole building - metal siding/roof). I plan to install the all of the electrical and have a question about wiring protection. FYI - this is my first home/garage wiring project.

Per NEC 300.4 "Protection Against Physical Damage" it states "Where subject to physical damage, conductors shall be adequately protected."

Questions:
1. Since my building has a ceiling height of approximately 12', is it acceptable to run my wiring (NM sheathed cable) along the sides of the trusses/bracing/eave purlins etc. (all wiring to be run @ 11' to 12' above ground) without providing protection such as EMT,FMC, PVC, etc.? i.e. is a ceiling with all exposed framing and structural members typically viewed as an area that would require protection of wiring?

2. I was thinking I'd affix the NM to the wood members with plastic cable staples or U-shaped nails. If the answer to question #1 is "yes" then how would you affix the NM to the wood members in the ceiling? FYI, this building will not have any drywall installed; all framing and structural members are exposed.

Thanks in advance or the response.
