When I read this book by Carol Fey,
I knew it was going to be easy to understand, but what delighted me was
how she got into things such as why a two-wire cable has three wires, and
why a three-wire cable has four wires, and why the switches at the top
and the bottom of our stairs here at home are called three-way switches,
which doesn’t make sense at first since there are only two of them.
Makes sense now, though. This book is a delight. I also loved the way she
handled the subject of GCFI outlets, low-voltage circuits, and
troubleshooting. She has shown me the magic behind the walls!
