Neighbor who is handier than I put in transfer panel and said it took
all day.
He did not want to help me - I'll hire electrician.

Mine took about 4 hours. Half that time was running the 8/3 cable and most
of the rest was rewiring the switch from plug in to direct wire.
Actually connecting the switch was maybe 30 minutes.
