This is a lot safer since the transfer switch is interlocked so the utility power can't backfeed the generator inlet. |

Surely you don't mean paralleling (jumpering) both phases so they act as a single phase?!? How would that work for 240VAC loads? At best they'd see a net 0VAC across their inputs. |

It's fun to play "What can I Rube up and make work in a pinch today" but when dealing with line voltages that can be a dangerous game. |
