We design a lot of commercial buildings that are Pre-engineered metal buildings (PEMB). I would like to provide better direction on a set of plans for the mounting and installation for the electrical work in general. Mainly, along the wall when we cant get stuff on columns. Sometimes we have a few courses of block and sometimes we dont. I've left it pretty generic because I don't want to force things a certain way but I would like to know some good practices the look as clean as possible and still meet NEC support requirements. There is a lot of things like this but this is a big area that my lack of "doing" is limiting the direction I can give. Does anyone have any good resources or recommendations, or even photos. Ive searched some of the PEMB websites for recommendations and even looked through some previous design drawings from them but nothing is coming up. Thanks in advance
