I would like to remove an existing cable from the breaker panel, that feeds a single home run outlet, and wire it to a consumer UPS that I will locate near the panel, through a junction box.
Questions:
- To join the power cord from the UPS to the junction box can I put a NEMA 5-15 inlet on the box and use a consumer power cord?
- Instead of a NEMA inlet (a) could I do it with an IEC C14 inlet? (b) could I just insert a consumer power cord into the box with strain relief and splice wires inside the box? This would all be on the surface near the breaker panel, nothing inside walls but also no conduits.
- As a further optional step, if the junction box additionally is fed raw power and I add a switch to bypass the UPS, can I just switch the hot or must the neutrals be switched too? The grounds? I assume the UPS input and output grounds are bonded but I don't know about the neutrals. The inlet hot would never be connected to the raw power hot, but is there still any unacceptable danger in this arrangement?
This question is instructive but the answers focus on the practicality of running new cable from room to room. My situation is to use existing, to-code, wiring from the basement to the room, and adds the idea of switching to raw power.
