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). In ...
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.
There are several alternatives for connecting newer appliances to two-prong receptacles without rewiring the building: removing the grounding pin of the plug (unsafe), replacing the receptacle with a three-prong outlet (unsafe without proper ground), or replacing the receptacle with a Ground Fault Circuit Interrupter (GFCI).
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 ...
Each type specifies characteristics of an enclosure, but not, for example, a specific enclosure size. Note that higher numbers do not include the lower-numbered tests. For example, types 3, 4 and 6 are intended for outdoor use, but type 5 is not. A NEMA enclosure rating does not mean that it also meets the same UL enclosure rating. [2]
Hubbell had been one of the first to manufacture flush toggle switches for alternating current only. The first Safety Receptacle was designed and produced as were the original "grounding only" devices which helped to set the standards for the industry. And while Hubbell was busy on land, the company found new opportunities at sea.
There are free-hanging wire and circuit board mounted versions of both tabs and receptacles. All widths come mostly in one of two tab thicknesses: 0.032 and 0.020 in (0.8 and 0.5 mm). All widths come mostly in one of two tab thicknesses: 0.032 and 0.020 in (0.8 and 0.5 mm).
Tamperproofing is a methodology used to hinder, deter or detect unauthorised access to a device or circumvention of a security system. Since any device or system can be foiled by a person with sufficient knowledge, equipment, and time, the term "tamperproof" is a misnomer unless some limitations on the tampering party's resources is explicit or assumed.
