2. Wetting current - Wikipedia

   en.wikipedia.org/wiki/Wetting_current

   A related term sealing current (aka wetting current or fritting current) is widely used in the telecommunication industry describing a small constant DC current (typically 1-20 mA) in copper wire loops in order to avoid contact oxidation of contacts and splices.

3. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   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 ...

4. Earth-leakage circuit breaker - Wikipedia

   en.wikipedia.org/wiki/Earth-leakage_circuit_breaker

   An earth-leakage circuit breaker (ELCB) is a safety device used in electrical installations to prevent shock. It consists of either a current sensing mechanism, or a voltage sensing mechanism. Such a protection mechanism may be found in the form of distribution board modules, standalone devices, and special sockets (aka receptacles ).

7. Contact protection - Wikipedia

   en.wikipedia.org/wiki/Contact_protection

   When the contact is operating under power (wet), the sources of the wear are the result of high current densities in microscopic areas, and the electric arc. [2] Contact wear includes material transfer between contacts, loss of contact material due to splattering and evaporation, and oxidation or corrosion of the contacts due to high ...

9. Electrical wiring in North America - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_North...

   The Code gives rules for calculating circuit loading and maximum ampacity. Ground-fault circuit interrupter (GFCI) protection is required on receptacles in wet locations and locations where there exists an easy path for fault current to travel to earth. This includes all receptacles intended to service kitchen counter surfaces, crawl spaces at ...
