How do you make a generator cord that would be a four prong male plug on one end and a three prong male end on the other for a 240v 30a that would plug into a house wall plug?

If your generator is designed to work as backup power for a house, it will be wired to your electrical feed through a transfer switch. If you attempt to power your house through a plug-in connection, particularly a 120V connection, you will probably not power the entire house and all the power that your house uses will be fed through one circuit breaker. An improperly installed back up generator is very dangerous, and is unlikely to work as you hope.

These types of extension cords are dangerous. This is because the end that plugs into the generator is a male end. The other end of the cord must be a female end so as to not have "hot" exposed blades on the other end. To tie a generator into an existing distribution system, a double pole double throw switch must be used. This is so that the utilities distribution system can not be energized by the generator. From the emergency side of the DPDT switch install an extension cord with the male end on it. In normal operation these exposed blade ends will be de energized. When the generator is needed, plug this short cord from the switch into the generators extension cord. Turn the DPDT switch to the emergence generator side and the load will be energized from the generator. Back feeding a generator into an existing house plug can and has killed linemen working on the primary side of the system during a power outage. The home owner forgot to shut his main breaker off. These types of installations leave the homeowner open to litigation.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances
always use a test meter to ensure the circuit is, in fact, de-energized.

Wire connected to the rounded prong in a three prong plug?
The equipment grounding conductor is attached to the rounded prong in a three prong plug. Electrical work is dangerous, call a qualified electrician to install. Improper wiring could lead to personal property damage, you or someone else being injured or killed!
What is wrong if you changed a four prong to a three prong and the dryer is not heating?
My question is WHY did you replace a four prong dryer plug with a three prong! 220 volt Electric dryers require two hot legs, a neutral and a system ground wire. Sounds as though you shunted one of the hots or the neutral. You need to install a four prong plug of the same configuration and wire it exactly as the original.
How do you make an extension cord that would be a four-prong male plug on one end and a three-prong outlet on the other for 240V 50A that would plug into a generator to power a welder?
Answer for UK, Europe and countries running a 50 Hz supply service.A four-prong socket on the generator implies that it's a 3-phase generator.The welder appears to be single-phase load working at 240 v 50 A but provided the generator is rated at 415 v 36 kVA that means it can supply 240 v 50 A on each phase, between line and neutral.Given the voltage and power of the generator an electrician should be employed to identify the socket correctly, do the wiring and ensure earthing is correctly completed. Without this the system is dangerous, someone could get electrocuted.
What type of appliances have three prongs?
The third prong is to protect from shock. If there is any way for you to come in contact with a conducting surface on the appliance you have the third prong.
