Reader Says What?
Your July 2106 issue just arrived, and I was reading your very appropriate article on GFCI outlets (Circuit, Interrupted, p. 22). Your writer gave a good non-technical description of the device and the need for regular testing, but made one error (IMHO) and one omission. The error is that it’s not likely that a circuit breaker will trip if you get shocked by touching the hot wire since the current will be minimal — much less than the trip rating of the circuit breaker. The omission is that there are inexpensive plug-in testers that will allow testing of the GFCI and all downstream protected outlets. I have one at home and one on the boat, and test all GFCI outlets regularly. It also tests for reversed connections, missing grounds, and other related problems.
