  • Great post, but there's a mistake in the description of GFCI outlets (I know it's an older tutorial, but it should be corrected): a GFCI does not shut off current if it detects an "abnormal amount of current"; that's what a breaker does. A GFCI shuts off current if it detects a current imbalance between the line and return wires. A GFCI isn't going to protect you from shocks, or protect an element that's malfunctioning from overload; what it protects against is current being routed outside the system (aka, a "ground fault"),

No public wish lists :(
