Angie's List and NBC Bay Area both highlighted an October 2002 ruling in a New Jersey Superior Court, which found that FPE (Federal Pacific Electric), the manufacturer of the Stab-Lok breakers and panels, "knowingly and purposefully [sic] distributed circuit breakers which were not tested to meet UL standards as indicated on their label".
Zinsco would remain with copper in both their panels and breakers until the third major copper shortage in the early 1960s, when they would switch to an aluminum bus. In 1963, Zinsco introduced the R-38 twin breaker, which was the only twin circuit breaker that also made contact on both bus-bars for 240 volts in a single breaker space.
Ordnance crest "WHAT'S IN A NAME" - military education about SNL. This is a historic (index) list of United States Army weapons and materiel, by their Standard Nomenclature List (SNL) group and individual designations — an alpha-numeric nomenclature system used in the United States Army Ordnance Corps Supply Catalogues used from about 1930 to about 1958.
Residual-current device (RCD), also residual current circuit breaker (RCCB) A circuit breaker triggered by unequal currents in line and neutral wires (i.e., electrical power is passing to earth). Mandatory for most circuits as of 17th Edition regulations. Residual current circuit breaker with overcurrent protection (RCBO)
A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.
Such devices may be found in the form of either a circuit breaker, known as an earth-leakage circuit breaker (ELCB), or built into a socket (aka receptacle). Voltage-operated ELCBs can still be found in the wild, though these largely fell out of favour after the invention of the current-sensing based RCD (aka GFCI) technology.
Circuit breaker – resettable fuse in the form of a mechanical switch; Resettable fuse or PolySwitch – circuit breaker action using solid state device; Ground-fault protection or residual-current device – circuit breaker sensitive to mains currents passing to ground; Metal oxide varistor (MOV), surge absorber, TVS – Over-voltage protection
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
