Doug, I can tell you how IT SHOULD BE WIRED such that a Genset could backfeed certain selected circuits (using a BRANCH circuit breaker) and often even via a separate sub panel if so choosen, such that there's no possibility of backfeeding the standard utiity service. They make relatively cheap mechanical slider lockouts whereby the MAIN breaker in a panel MUST BE OFF BEFORE THE BACKFEED BRANCH BREAKER (connected to genset) CAN BE SWITCHED ON. When the utility is hot and the main breaker is ON the backfeed branch circuit breaker (from genset) MUST BE OFF. That way the utility cant fry the genset nor can the genset kill a lineman.
Often when wiring a garage or shop or simply other small loads served by their own separate panel, the small sub panel is fed by a BRANCH circuit breaker in the main panel. If so for 120/240 single phase three wire service THE SUB PANEL NEEDS SEPARATE INSULATED AND ISOLATED NEUTRAL AND GROUND BUSSES
NOTE: When transfer switching from utility to genset, the Genset needs to be configured with a FLOATING NEUTRAL in some cases, but A BONDED NEUTRAL IN OTHERS. It makes a difference in if your switching or bonding the Utility and Genset Neutrals..Ask your electrician about that !!!!
NOT being there I hesitate to venture a guess as to exactly how its wired now (my advice offered above is standard and generic in nature) but I will offer my same standard advice, where fire and life safety is concerned at least consider consulting current practicing (NOT me I'm long retired from power distribution design) professional engineers and electricians and DONT RISK YOUR LIFE ON LAY OPINIONS !!!!!!!!!!!!!

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
