A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
Receptacles protected in this manner or with a GFCI circuit breaker should be labeled "GFCI protected". (Outside North America these are referred to as a "Residual-current device" or RCD.)

A home inspector will look for missing, curling, or crumbling shingles. Depending on its condition, or if your roof is over 20 years old, your inspector might suggest you budget for a new roof ...
If the installation's Earth rod is placed close to the Earth rod of a neighbouring building, a high Earth leakage current in the other building can raise the local ground potential and cause a voltage difference across the two Earths, again tripping the ELCB.
Installing a single receptacle is often cheaper or more convenient than providing this GFCI protection at the circuit breaker. In addition, a tripped GFCI receptacle may be more easily noticed and reset, as compared to a tripped GFCI located in a remote circuit breaker panel far from the point of usage.
Old homes may still use older heating and cooling systems or have fewer electrical outlets than you’d like. Similarly, these homes might not be up to modern code, and renovating to bring things ...
