Envelope #19: GFCI outlet and structural engineering?

Happy Thursday – This is Back of the Envelope, where I share SE-related tip bits that help you become smarter (I hope).

Today, I am going to talk about GFCI outlets.

(Wait… what?)

You know, one of those electrical outlets with two buttons in the middle. You typically find them in the bathrooms and kitchens.

“But how is that related to structural engineering?”

Well, not directly, but there are some inferences that I’d like to share. Bear with me here – it’ll be fun!
