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 wanna see pics of some hot rack on rack action!

Haha rack on rack, damn it's been a long day! What's on my mind!

Your problem may be if the support for the original rack will not carry the 2nd rack.

I see rack on rack action all the time, sometimes tripple and quad rack action


Go ahead and hack that young rack on an older rack

Ive done rack on rack only once, but I still talk about it.

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.

Thanks everyone for the suggestions

This is pretty common. Rod couplings are your friend

Rack on rack is always acceptable and encouraged, but crossing swords is never cool!

If the existing rack is supported by threaded rod and you want to install the new rack above the existing one you can use those split nuts and slot the end of your new strut so you don't have to take anything apart.
