While at the local electrical supply house recently, I overheard a DIYer asking the counter man how to install a residential generator transfer switch. To my surprise, the counterman began to explain the connections to him. Then I got to wondering..
If the DIY guy mistakenly miswired the utility and common connections, and properly made the generator connection, upon throwing the transfer switch and starting the generator, the utility transformer would be back-fed, thereby providing primary voltage to the transformers input terminals and potentially harming(or worse)a utility worker. I thought about intervening, but chose not to. Any thoughts?
