I have two computers, one in the basement and one on the third floor, which I would like to run off the same plug-in UPS (expensive, so I don't want to purchase another one). There is already conduit going up to the third floor. What do I need to properly (to-code) install a UPS protected outlet on the third floor which shares the plug-in UPS in the basement? Is there a code-compliant solution? Are you allowed to plug a cord into a UPS which goes into a junction box, is spliced to THHN, and then into the house wiring?
Thank you for your time, William
PS: I am not asking for instructions on how to install an outlet. The outlet that the UPS plugs into in the basement is already GFI protected. There are enough spare cubic inches in the box to support an additional device and wiring.
