How to test single phase twist lock receptacle to verify 120v or 220v and if its 120v how to find which wire is "hot" and what wires are neutral and ground.
Great content and very actionable; I wound up in a usual situation. I was looking for 3 phases, 30a, 240v, 4 pole, 5 wire diagram. Then realized I only have enough room in my main box for a two-pole breaker: so, I need to change the plug on the end of the PDU from a 5 wire to a three wire; so, I am trying to determine which wires, (colors) to connect to which poles; which would make this process much easier, since I haven't ever wired up a three-phase outlet receptacle before. If you could point me to a good reference point; or walk through that would be great.
If I have a L5-30 outlet and use 10/2 wire to get power from my 3500 watt generator to power up my house, of course limited only and with 120 only, what wires do I attach to my 30 amp double pole breaker? Would I attach the black and white to a double pole?
Are they labeled? You may have labels such as L, N, G L=hot or black (in us). N= neutral or white (is us). G= ground. Sometimes may also be X,Y,G X is hot Y is neutral. G is ground. Also if you look at the prongs that actually plugs in to the female receptacle they may be color coded and 2 of the prongs are the same size/shape those are hot and neutral. The larger of the 3 prongs that also has a 90 angle on it is the ground.
