The electrical room we are working in is really tight and there is a lot of emt being ran. I'm thinking about building a rack on top of another rack. I don't see anything in the CA building codes that says that I can't. I called the building inspector for that City and he told me to ask someone else lol!! Thanks

I think heat dissipation may be a problem

I see it all the time. The key is the working within the hardware limitations. You may need an engineers aproval in some spots.
Depending on the site.
Also being in California you may have seismic issues of bracing to contend with.
If there is no other way, just make sure to support your rack individually where possible.
I don't believe heat will be an issue.

If you visit some of the strut manufacturers websites they will have loading information for different sizes of strut, allthread, and weights of different sizes of conduit with wire. That should get you started.

Erico Caddy may have some info too.
