How do you connect a 4 prong generator twist and lock and 4 wire cable to a 3 prong transfer sw receptacle?

Answer 1

Generally, the screws that the wires go on are color coded. The two hot wires(black & red) go on the brass colored screws, the white goes to the silver screw, and green goes to the green screw. There are many variations on the configuration of the plug, so no answer would be foolproof. There should be some kind of diagram that came with the plug though. It would also be best to turn off all breakers to the load, and check for proper voltages when the generator is running before turning breakers back on and using the power.

Answer 2

Your question is likely based on the mistaken impression that you can power your house this way if there is a power outage. If you are even thinking this you are not capable of pulling this off without potential dire consequences. There is no polite way to say this, you would be stupid to try this. McIver could do this, but you shouldn't try this unless you want to burn down your house and perhaps kill you and your family. To provide backup generator for your house you need an automatic or manual transfer switch to connect the generator.

Answer 3

The four blade receptacle that is on your generator has the ability to to generate 120/240 volts. This is what your house voltage is 120/240. To take advantage of the generators output you should be considering using a four wire installation to the transfer switch. By only using a three wire you will only be able to supply either 120 volts or 240 volts but not both. Depending on the amperage configuration of the generator receptacle the top blade hole should be the neutral, bottom blade hole the ground and across the left and right blade holes 240 volts or left to top 120 volts and right to top 120 volts.

Answer 4

You will need to install a 4-prong to 3-prong adapter plug to connect the 4-prong generator twist and lock to the 3-prong transfer switch receptacle. Make sure the grounding wire is properly connected to the grounding terminal of the transfer switch receptacle. It's important to follow safety guidelines and consult an electrician if needed.
