A Must Read Book

The fourth edition of Earl Roberts’ book, Overcurrents and Undercurrents, subtitled “All about GFCIs, AFCIs, and Similar Devices, Plus New Safety Product Ideas” is now available at a special price for all Mike Holt Newsletter readers.

This book contains over 200 pages and 45 illustrations, and it details the history of electrical shock and electrical fire protection progress.

Mike Holt’s Comment: Earl is a great friend of mine and an outstanding historian on the progress of electrical safety. I encourage you to purchase this book and take the time to read it. I’ll be taking a vacation in the next few weeks - I have my copy and my plan is to read it again this year.
