When you get tangled up in a live circuit, you can come in series contact with ground or in parallel contact with ground. Grounding can only protect you from the hazards of parallel contact. GFCIs will protect you in either situation. ESTA’s Technical Standards Program has a new proposal regarding the use of GFCIs, recommending their use in any situation that might be wet or damp…Had RCDs and GFCIs been more widely used in the 1960s and 1970s, we might not have lost Leslie Harvey of Stone the Crows, John Rostill of the Shadows and Keith Relf of the Yardbirds. Today, we know better. Let’s not let one more person be injured in an accident that could have been prevented.
