Electrical installations. An earthing system (UK and IEC) or grounding system (US) connects specific parts of an electric power system with the ground, typically the equipments conductive surface, for safety and functional purposes. [1] The choice of earthing system can affect the safety and electromagnetic compatibility of the installation.
5-4-3-2-1. "5-4-3-2-1" is a 1964 song by British band Manfred Mann, written by the group's eponymous keyboardist Manfred Mann along with Mike Hugg and Paul Jones. Released as a single on 10 January 1964, the track peaked at #5 on the UK Singles Chart, [1] becoming the band's breakthrough single and first commercial hit as the theme tune for the ...

The designation NM XX-Y indicates, respectively, the type of sheathing (in this case, non-metallic), the size of the main conductors, and the total number of circuit conductors (exclusive of the grounding conductor). For example, NM 14-2 cable contains three conductors (two plus one ground) at 14 gauge, a size typically used for circuits ...
v. t. e. The Boeing 737 MAX passenger airliner was grounded worldwide between March 2019 and December 2020 and again in 2024 – after 346 people died in two similar crashes in less than five months: Lion Air Flight 610 on October 29, 2018, and Ethiopian Airlines Flight 302 on March 10, 2019.
A grounding transformer or earthing transformer is a type of auxiliary transformer used in three-phase electric power systems to provide a ground path to either an ungrounded wye or a delta-connected system. [1][2] Grounding transformers are part of an earthing system of the network. They let three-phase (delta connected) systems accommodate ...
5-4-3 rule. The 5-4-3 rule, also referred to as the IEEE way, is a design guideline for Ethernet computer networks covering the number of repeaters and segments on shared-medium Ethernet backbones in a tree topology. [1][2] It means that in a collision domain there should be at most 5 segments tied together with 4 repeaters, with up to 3 mixing ...
In kinematics, a five-bar linkage is a mechanism with two degrees of freedom that is constructed from five links that are connected together in a closed chain. All links are connected to each other by five joints in series forming a loop. One of the links is the ground or base. [1] This configuration is also called a pantograph, [2][3] however ...
