My neighbor tells me to get a transfer switch. What is that exactly?
A transfer switch is a device that is fed by both utility and generator power. It isolates the two types of power from each other so a back feed does not occur. National Electrical Code requires a device like this if two types of power are going to feed the house. Always get a qualified electrician to install your transfer switch. The potential danger to workers and neighbors from back feed is great when utility power is restored unless your transfer switch functions properly.
