The Importance of Using a Breaker Lock for My Generator

I learned the hard way that having a breaker lock for my generator is absolutely necessary. A few years ago, during a power outage, I decided to use my portable generator to power some of my appliances. However, I forgot to turn off the main breaker in my house before starting the generator.
