I am an electrical engineer working in San Jose, Costa Rica. We try to apply NEC in Costa Rica as much as local conditions permit.
It is standard prectice here to do concrete trenches within electrical rooms (in the floor) and then do feeders between panelboards using those trenches. Some sort of cable tray will usually be installed inside the trench and the cable would be laid on top of the trench.
Would this be and acceptable practice per NEC?
What would be the limitations on cable gauge that could be installed there?
What would be the limitations on the cross section?
I thank you for your help.
