An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...
If the size is not known, it is difficult to distinguish by eye or measurement between the 2.1mm and 2.5mm ID plugs; some suppliers suggest simple methods. [ 1 ] Maximum current ratings commonly vary from unspecified up to 5 A (11 A for unique high-power versions from some companies [ 2 ] ), with 1 A, 2 A, and 5 A being common values. [ 3 ]
NEMA 1-15P (two-pole, no ground) and NEMA 5-15P (two-pole with ground pin) plugs are used on common domestic electrical equipment, and NEMA 5-15R is the standard 15-ampere electric receptacle (outlet) found in the United States, and under relevant national standards, in Canada (CSA C22.2 No. 42 [1]), Mexico (NMX-J-163-ANCE) and Japan (JIS C 8303).
An extended specification, THWN-2 permits use in wet locations and conductor temperatures up to 90°C simultaneously. [18] There are additional restrictions on such wire's use not mentioned here (for example, neither THHN nor THWN may be exposed to sunlight, or directly buried in the ground [20]); see the NEC for details.
Clock diagram for the regular (>50 V) connector series, viewed looking in to the socket end. The extra-low voltage connector also supports keying, although in this case the angle is the position of the minor key, assuming the major key is at the 6h position (180°).
The first types of small modular telephone connectors were created by AT&T in the mid-1960s for the plug-in handset and line cords of the Trimline telephone. [1] Driven by demand for multiple sets in residences with various lengths of cords, the Bell System introduced customer-connectable part kits and telephones, sold through PhoneCenter stores in the early 1970s.

The CEE 7/5 socket and CEE 7/6 plug are defined in French standard NF C 61-314 "Plugs and socket-outlets for household and similar purposes" (which also includes CEE 7/7, 7/16 and 7/17 plugs) The socket has a predominantly circular recess which is 15 mm (0.591 in) deep with two symmetrical round apertures and a round 4.8 mm (0.189 in) earth pin ...
The connectors on the cord are connected pin for pin, (pin 1 to pin 1, etc.). Pins on male connectors are numbered (from right to left, viewed from outside of the connector, with the five pins upwards, and facing them): 1–4–2–5–3. Holes on female connectors are also numbered 1-4-2-5-3, but from left to right (facing the holes).
