BS 1362 specifies sand-filled ceramic-bodied cylindrical fuses, with dimensions of 1 in (25 mm) in length, with two metallic end caps of 1 ⁄ 4 in (6.4 mm) diameter and roughly 1 ⁄ 5 in (5.1 mm) long. The standard specifies breaking time versus current characteristics only for 3 A or 13 A fuses.
CEE 7 is a standard for alternating-current plugs and sockets.First published in 1951 by the former International Commission on the Rules for the Approval of Electrical Equipment (), it unified standards produced by several continental European countries.
SN 441011-1: Description of the systems with risk analysis and national deviations from the IEC 60884 series; SN 441011-2-1: Standard sheets and construction specifications for plug-in devices with degrees of protection IP20 and IP55; SN 441011-2-2: Multiple and intermediate adapters, extension cables, socket strips as well as travel and fixed ...
The ground hole is officially D-shaped, although some round holes exist and many plugs have round ground pins. Both current-carrying blades on grounding plugs may be narrow, since the ground pin enforces polarity, but outlets have a wider opening for the neutral blade to prevent ungrounded polarized plugs from being put in backwards.
IEC 60906-1 (IEC designation "Type N") [1] is an international standard designed "to provide a standard for a safe, compact and practical 16 A 250 V AC system of plugs and socket-outlets that could be accepted by many countries as their national standard, even if not in the near future."
A variety of different kinds of IEC 60320 plugs and sockets. IEC 60320 Appliance couplers for household and similar general purposes [1] is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A. [1 ...
The fluorescent green spacers, which firmly attach the receptacle to the metallic sub-structure, are made necessary by using 5 ⁄ 8 in (16 mm) drywall instead of 1 ⁄ 2 in (13 mm), or by slightly-misplaced device box housings. Over time, electrical codes in the US and Canada began to require additional safety features in the basic NEMA 5-15R ...
The symbol connected to the dot (usually the symbol found to the right) denotes the polarity of the center/tip, whereas the symbol connected to the broken circle denotes the polarity of the barrel/ring. When a device or adapter is described simply as having "positive polarity" or "negative polarity", this denotes the polarity of the center/tip.
