The GE-215 (1963) [3] [8] was a scaled-down version of the GE-225, including only six I/O channels and only 4 kilowords or 8 kilowords of core. The GE-205 (1964). [2] The GE-235 (1964) [3] was a re-implementation of the GE-225 with three times faster memory than the original. [9] The GE-235 consisted of several major components and options ...
A thermal switch (sometimes thermal reset or thermal cutout (TCO)) is a device which normally opens at a high temperature (often with a faint "plink" sound) and re-closes when the temperature drops. The thermal switch may be a bimetallic strip , often encased in a tubular glass bulb to protect it from dust or short circuit .
Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure. Wiring is subject to safety standards for design and installation.
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.
The first two-way radio remote controls utilized a harness of wires extending speaker, microphone, and controls for options such as channel selection or CTCSS switches. This limited a base station to being within tens to hundreds of feet from the user's workstation. Early systems often had volume unit meters, clocks, and switchboard keys. [4]
Safety regulations of the utility must prevent any attempt to open the disconnector while it supplies a circuit. Standards in some countries for safety may require either local motor isolators or lockable handles (which can be padlocked). IEC standard 62271-102 defines the functionality and features of a disconnector.
From 2010 to late 2014, GE Appliances & Lighting was a sub-business under GE Home & Business Solutions. [ 12 ] On September 8, 2014, General Electric agreed to sell the company to Electrolux , a Swedish appliance manufacturer and the second-largest consumer appliance manufacturer after Whirlpool Corporation , for US$3.3 billion in cash.
The toggle light switch was invented in 1916 by William J. Newton. [2] As a component of an electrical wiring or home wiring system, the installation of light switches is regulated by some authority concerned with safety and standards. In different countries the standard dimensions of the wall mounting hardware (boxes, plates, etc.) may differ.
