"Why build a cord? Why not use a 4-wire cord and leave neutral flapping in the breeze? It's harmless." No, it's not.
It connects normally and safely, either to the generator or hardwired NEMA 14 socket wired into the electrical grid. Now you have an "adapter cable" you can use for North American testing of the equipment. The other end could be any of the following: Really simple: you use a 3-wire cord that has a NEMA 14 male plug, and you don't hook neutral to any wire. The NEMA 14 series is the universal socket, because it provides neutral in case it is needed. Getting from "universal donor" NEMA 14-30 to 240V-only The best cure is to reduce the amount of "imagining rules" that you do, actively avoid sophomorism, and simply listen to best advice from the experienced. Generally, if a person feels brutalized by incessant safety warnings from concerned citizens, it's because they have communicated loathing or alarming ignorance for the above rules or the electrical code generally. Real simple: bolt it to the machine before you plug it into the wall. Now, what happens with a cord that is male plug at one end, and bare wires or lugs at the other? (e.g.
That is simply so the energy sources are always shielded (by virtue of the sockets being female).
220 PLUG WIRING 4 PRONG HOW TO
The first corollary of that rule is that no cord may have male plugs on both ends. Every four-prong, 240-volt outlet or plug has a terminal for each of the hot wires as well as for the neutral and ground.

Things which supply power must have female sockets, and things which draw power must have male plugs.
