I got a call from a homeowner the other day.
He said he was replacing the switches in his mobile home and now his breaker kept tripping.
I went out and found that he had these type of devices in his mobile home. He had removed them and was installing Decora switches in their place without a box. I installed boxes so that the Decora switches could be installed. His connections to the switches were very poor. It's a good thing that they didn't work and the breaker was tripping. I find alot of bad connections done by homeowners. Wires twisted together with just tape over the connection and no wirenut. I'm surprised more houses don't burn down.
