GFI
God, I don’t know why this drives me up a wall so much. It shouldn’t, but it does. I so badly want to scream ITS GFCI
Yeah, well, that ship has sailed even worse than the bay-lun ship.
I first heard it called a GFI, maybe around 1980. GFCI came later. And these were required by code starting in 1971! They are also called ALCIs. All these things are RCDs (or RCCDs), and a combo unit is an RCBO.
The CPSC Fact Sheet from September 2010 starts out
A ground fault circuit interrupter, called a GFCI or GFI,....
And are you ready for this from Wikipedia?
In the
United States and
Canada, the device is called a
ground fault circuit interrupter(
GFCI),
ground fault interrupter (
GFI) or an
appliance leakage current interrupter (
ALCI). In the
United Kingdom, these devices are known by their initials
RCD, and a combined RCD+MCB (
miniature circuit breaker) is known as a
RCBO (
residual-current circuit breaker with overcurrent protection). In
Australia a protection device with this function is called a
Safety Switch or
RCD.
They are all RCDs. Try calling it that!
A residual-current device (RCD), or residual-current circuit breaker (RCCB), is a device that instantly breaks an electric circuit to prevent serious harm from an ongoing electric shock. Injury may still occur in some cases, for example if a human falls after receiving a shock.
