Hello..

Last year when the power went out I managed to hook my Gen to my pressure switch on my well.

I tried to do it this year and the second I turn on the power at the generator it blows the braker.

Here's what I did.

I disconnected the two leads on the out sides of the pressure switch (black and white) this is the power coming in. I attach my 2 leads from the gen.

Now the tricky part. I hooked up my plug to the cable.

I used the white and black lines. I attached the white and black to the "long" blades. This would not be the (G) or the (N). I still hooked up the Green to the Ground cause I could, and made sure the other end of the cord was taped off.

Now this is the same set up I used last year except it's a new plug and cord.

Why is the braker on the Gen Blowing. .

I did Isolate the well from the house power so there is no chance of be back flowing onto the grid..

Assuming this is all wired properly, we have no idea, there must be a short somewhere. You will need a volt and ohm meter.

Measure the generator plug, should be 240 volts.

Unplug the cable from the generator and disconnect the wiring at the switch. Use a ohm meter and test across the two feed wires, there should be no reading. Test across each of the feed wires and ground, there should be no reading.

Try connecting the feed to the generator and leave the switch disconnected, see if the generator will send power without tripping. You should get 240 volts to the wiring at the switch.
