When overheating, the temperature of the part rises above the operating temperature. Overheating can take place: if heat is produced in more than expected amount (such as in cases of short-circuits, or applying more voltage than rated), or; if heat dissipation is poor, so that normally produced waste heat does not drain away properly.
To avoid this, the cored fusible plug was developed in the 1860s to give a wide opening as soon as the alloy softens. This has a solid brass or bronze centre, soldered into place by a thick layer of the low-melting-point alloy. When overheated, the plug does not release any steam or water until the alloy melts sufficiently to release the centre ...
Internationally, the NEMA 5-15P plug and NEMA 5-15R receptacle are the basis for the International Electrotechnical Commission's IEC 60906-2 standard IEC system of plugs and sockets-outlets for household and similar purposes – Part 2: Plugs and socket-outlets 15 A 125 V a.c. and 20 A 125 V a.c. [24]
The standard specifies both a 2-pin unearthed and 3-pin earthed plug system, equivalent to IEC Type N. SANS 164-2 was designated the "preferred standard" in 2013, and South Africa is in the process of transitioning to it as the dominant system, expected to be completed by 2025 to 2035.
Schuko sockets can accept two-pin unearthed Europlug (CEE 7/16) and CEE 7/17. Less safely, Schuko plugs can be inserted into many two-pin unearthed CEE 7/1 sockets and into some sockets with a different form of earth connection that will not mate with the earth contacts on the Schuko plug (e.g., some variants of the Danish socket).
Ryobi Limited (English: / r aɪ ˈ oʊ b i / ry-OH-bee or / r i ˈ oʊ b i / ree-OH-bee; Japanese: リョービ株式会社, romanized: Ryōbi Kabushiki-gaisha, IPA: [ɾʲoːꜜbi]) is a Japanese manufacturer of components for automobiles, electronics, and telecommunications industries.
A power conditioner (also known as a line conditioner or power line conditioner) is a device intended to improve the quality of the power that is delivered to electrical load equipment. The term most often refers to a device that acts in one or more ways to deliver a voltage of the proper level and characteristics to enable load equipment to ...
IEC 60884-1 para 9.2 does stipulate that "it shall not be possible, within a given system, to engage a plug with a socket-outlet having a higher voltage rating or a lower current rating". IEC 60884-1 para 6.1 defines the preferred voltage ratings for single phase plugs and sockets as 130 V or 250 V.
