People make mistakes. I might have done something like that until reading the article. This caught my eye, > the flow of electric power in the direction reverse to that of the typical flow of power circumvents safety features of the home’s electrical system and can result in a fire. At first I thought they were BSing. A fuse doesn’t care which side is the source, it blows on current. I kept thinking about it and realized what they’re talking about. If you plug a 30a generator circuit into a 15a circuit and then draw more than 15a on that circuit (thereby avoiding the fuse/CB), you’re going to have a bad time. Similarly, even if you’re only drawing 15a on that circuit, but you draw another 15a on another (15a bypassing the fuse and 15a going thru the fuse), you’re still going to have a bad time. It’s a very specific set of circumstances, but it probably happens more than you would think. Because of the fact that they’re only energizing half their circuits, they probably start moving loads to working outlets.
