David Shapiro
David Shapiro has been a licensed electrical contractor and consultant in the Washington, DC area for a bit over thirty years. He's also IAEI-certified as an inspector (both general and 1-2 family) and plan reviewer. Maryland and Washington, D.C. have authorized him to perform third-party inspections, focusing on residential work.
As a member of IAEI, you probably know him best as secretary of the George Washington Chapter--that is, unless you read his long-running Residential Wiring column in Electrical Contractor. At the same time as he's worked with his tools, he's written and edited articles, columns and books. He is proudest of Old Electrical Wiring and Your Old Wiring, and of his selection by Creighton Schwan to co-author Behind the Code.
