Terri, you don't have to say this.... They're all experts here....<p>Terri, you don't have to say this.... They're all experts here....<p>
If you are just noodling around, without power company approval, make sure you disconnect from the line if the outside power goes off so you don't have some poor lineman touching the lines that are still hot from your inverter, sychronous motor, or whatever, because he thought it was shut down from a distribution point.<p>Terri, you didn't have to say that...

Yeah, Terry, I have known about the possibility of cooking a lineman. I do know of a local farmer that obviously did not know ( or did not care :mad: ) about such things. Actually what happened was the utility had connected his double throw disconnect improperly, and when he flipped it over to auxillary power, the PTO driven generator was connected directly to the line. He claims that when he kicked the generator in, his 25 KW generator cart instantly flipped over on its back before it blew the breaker.

A synchronous generator lets the line make up the difference between its output and the power requirement. Its safe because it stops generating if the line shuts down.

And around here where the cows out number the line men 100 to one, we shunt our grid to ground with a dead short when working on sections. <p>Already installed on the major pole points, for exactly this reason.
