I guess I didn't really look hard enough at first it does say 240v on the furnace. I was looking at the other thing on the plate
it says 208 - 240v (120v ground) 60hz

So, short answer is no, you can't run normal 120V stuff on this circuit as it doesn't look like there is a neutral. All is not lost though, you still could put a couple 240V PDUs onto one of those circuits. As I linked, you could pick up a couple of cheap managed PDUs for $100 shipped. Any modern PSU can handle 240V and will be more efficient that way anyway. |

I've never used one before. how does it work? do I run the two 240v wires into it? or do I need to wire up a 240v plug??? I made the one for our dryer, so I've done that before. just not sure how they work, |

I also don't understand how they rate the PDUs. some of them say like max 16a?

ok this one has a decent explanation, it says max output 16a per socket

I have one of those, they're quite nice. Personally though, if I were buying more, I'd go with the Avocent posted as it's managed. |

how would I put more than one 240v socket if there is only one set of wires? |

Junction box, or perhaps a 60A subpanel. |

PDUs have two ratings. The first is the total rating, which in that case is 30A. The second is the per-outlet rating, in this case 10A. Why would you need 3 of them? For instance, while the Pulizzi one you linked has 24 C13 sockets (so probably 10-13A rated each), the whole bar is only rated to 20A in total. Three phase. You're looking to run 19 S1s, correct? You can downrate a receptacle, so here would be my minimal cost suggestion if you don't want your electric heater anymore. Install two utility boxes with a L630R. (~$50) Wire the two existing 50A lines to them. Buy two of the PM10i-30a's (~$100) Plug all your PSUs into the PDUs. Plug the fans/switches into a 15/20A 120V circuit on the wall. |

ok.
I contacted a place local that sells old hardware, they have some PDUs. some are 20a max and some are 30a.
some have L6-20 and some have L6-30.
this is my plan right now:
wire two L6-30 220v outlets from the existing wires running into the furnace.
buy two L6-30 PDUs with 30a max from this place, they want $30 a piece
if I want to go back to using the furnace at some point it'll be just a simple deal to remove the two util boxes and put the wires back into the furnace.
this place wants $30 per PDU and said they'll give me a bunch of shielded power cables with it
