  2. Generator interlock kit - Wikipedia

    en.wikipedia.org/wiki/Generator_Interlock_Kit

    A generator interlock kit (or a transfer switch), eliminates the need for extension cords to power appliances. [2]Like a transfer switch, an interlock kit lets the generator energize the panel and all of its circuits (up to the load capacity of the generator); not just corded appliances.

    Simplified single line diagram of a single-phase transfer switch to select either 'city' (utility) power or local generator power 3-phase Intelligent transfer switch. A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a ...

    {Beer bottles in South Africa were different from in other countries.} Dumpie [340 ml, 11.98 Imp. fl. oz.]: A short-necked recyclable beer-bottle with a rounded body; the word is a nickname for a person who is short and fat. It used to be 12 Imperial ounces [341 ml] (3/5 of an Imperial pint), like the Canadian "stumpy" beer bottles.

    South African National Standard 164: Plugs and socket outlets for household and similar purposes for use in South Africa is the South African Bureau of Standards' standard for domestic AC power plugs and sockets. As a former British colony, South Africa's electricity standards are of British derivation, and it uses 220/230 V at 50 Hz AC. [1]

    Comparison of a linear power supply and a switched-mode power supply Linear power supply Switching power supply Notes Size and weight: 0.12 W/cm 3, 88 W/kg [28] Smaller than linear power supply. Compared to linear, a SMPS that is 20 kHz is 1/4, 100–200 kHz is 1/8, and 200 kHz–1 MHz types can be even smaller. [28]: 5–8

  7. Power-line communication - Wikipedia

    en.wikipedia.org/wiki/Power-line_communication

    Power meters often use small transformers with linear amplifiers in the range of tens of watts. Most of the expense of any PLC system is the power electronics. By comparison, the electronics to encode and decode is usually small, in a special-purpose integrated circuit. Thus even the complicated OFDM standards can still be economical.

  8. Linear alternator - Wikipedia

    en.wikipedia.org/wiki/Linear_alternator

    A linear alternator is essentially a linear motor used as an electrical generator. An alternator is a type of alternating current (AC) electrical generator. The devices are often physically equivalent. The principal difference is in how they are used and which direction the energy flows.
