CSI (the Construction Specifications Institute) publishes the MasterFormat list to standardize the organization of construction specifications.

Where does an arc flash spec belong according to this standard? There is a designation for "Overcurrent Protective Device Coordination Study" (26 05 73) which I will probably use.

What CSI number does your organization use for arc flash specs?

FYI, after further googling, it appears that arc flash studies are generally placed in section 26 05 73.

Matt,
we've been using 26 05 70 as a catch-all for our studies (arcflash, coordination, harmonic, short-circuit, load-flow & voltage-drop, power factor correction). if I was starting from scratch though, i'd probably go with 26 05 73.

Matt,

We use 29 05 93 APPARATUS COORDINATION, INSPECTION, AND TESTING. Like Gil, we put all the studies in there. Our reasoning is that one company is going to create a model and do all the studies so we may as well save virtual ink rather than repeat the same requirements in different sections. Unless your client has a standard, you could use any section number that makes sense. The CSI titles are a beginning, not an end.
