A Leviton GFCI "Decora" socket in a North American kitchen. Local electrical code requires tamper-resistant socket in homes, and requires a GFCI for socket within 1 metre of a sink. The T-slot indicates this device is rated 20 A and can take either a NEMA 5-15 or a NEMA 5-20 plug, though the latter type is rare on household appliances.
A safer and more reliable alternative identified in the US and Canadian electrical codes is to replace the outlet with a Ground Fault Circuit Interrupter (GFCI) breaker outlet. [3] Cheater plugs are also used to break ground loops in audio systems. [5] This practice has been condemned as disregarding electrical safety.
A receptacle tester for North American wiring. An electrical outlet tester, receptacle tester, or socket tester is a small device containing a 3-prong power plug and three indicator lights, used for quickly detecting some types of incorrectly-wired electrical wall outlets or campsite supplies.
Tamper-resistant GFCI duplex receptacle type 5-20RA, which can take 5-15 and 5-20 grounding plugs and 1-15 non-grounding plugs These versions of the 5-15R or 5-20R receptacle are residual-current devices , and have "Test" and "Reset" buttons (and sometimes an indicator light which may be normally on or normally off per the vendor's design).
(This does not mean they always do, as practical performance depends on installation details and the discrimination enhancing filtering in the devices.) Therefore, by electrically separating cable armour from the cable circuit protective conductor, a devices can be arranged to protect against cable damage only, and not trip on faults in ...
The CEI 23-50 P 40 socket, which is quickly becoming the standard in Italy along with CEI 23-50 P 17/11, accepts CEE 7/4, CEE 7/7, CEE 7/16, CEE 7/17, CEI 23-50 S 10, CEI 23-50 S 11, CEI 23-50 S 16 and CEI 23-50 S 17 plugs; its drawback is that it does not accept SPA 11, SPB 11, SPA 17 and SPB 17 side-entry plugs; however almost no appliance is ...
However a 10 A 5-pin plug cannot fit a 32 A 5-pin socket, as the plugs are in different groups and not only are their diameters different, but the position of the conductors also varies by a few degrees (for example the group 7/8 32 A plug has its L and N pins at 9 o'clock and 3 o'clock, while the group 1/2 20 A plug has its L and N pins at 10 ...
IEC 60906-2 is based on the NEMA 5-15 and NEMA 5-20 plug and socket systems and was originally published in 1992. The object of this part of IEC 60906 is to provide a standard for a safe, compact and practical IEC 125 V system of plugs and socket-outlets that could be accepted by many countries as their national standard, now or in the near future.
