An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire typically four American wire gauge (AWG) sizes smaller than the wire that is being protected. For example, an AWG 16 fusible link might be used to protect AWG 12 wiring.
Many of these devices protect electrical systems and individual system components from damage when an unwanted event occurs such as an electrical fault. Historically, a single protective function was performed by one or more distinct electromechanical devices, so each device would receive its own number.
Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
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 ...
In traditional plumbing in the UK, the space-heating boiler is set up to heat a separate hot water cylinder or water heater for potable hot water. Such water heaters are often fitted with an auxiliary electrical immersion heater for use if the boiler is out of action for a time. Heat from the space-heating boiler is transferred to the water ...
They are both required to be accessed through a standardized data link connector defined by SAE J1962. Heavy duty vehicles (greater than 14,000 lb or 6,400 kg) made after 2010, [ 1 ] for sale in the US are allowed to support OBD-II diagnostics through SAE standard J1939-13 (a round diagnostic connector) according to CARB in title 13 CCR 1971.1.
American-standard AFCI (arc-fault circuit interrupter) unit circa 2018. The white 'pigtail' is a low-power neutral connection, hard-wired into the unit. Starting with the 1999 version of the National Electrical Code in the United States, and the 2002 version of the Canadian Electrical Code in Canada, the national codes require AFCIs in all ...
Electric fuses are used as a safety device, breaking a circuit by melting if enough current flows to heat them to the melting point. Electronic cigarettes vaporize liquid by Joule heating. Some food processing equipment may make use of Joule heating: running a current through food material (which behave as an electrical resistor) causes heat ...
