The appearance of this plug is sometimes confused with a NEMA 10 connector, rated for 240 V, but the NEMA TT-30 is a 120 V device. The hot and neutral blades are angled at 45° from vertical and 90° to each other, unlike NEMA 10 devices (where the angles are 30° and 60° respectively), also the plug is slightly smaller than a NEMA 10 and ...
Meets the requirements of the Mine Safety and Health Administration, 30 CFR Part 18 (1978). 11: General-purpose. Protects against the corrosive effects of liquids and gases. Meets drip and corrosion-resistance tests. 12 and 12K: General-purpose. Intended for indoor use, provides some protection against dust, falling dirt, and dripping non ...
The enclosure is the only part of the equipment which is seen by users. It may be designed not only for its utilitarian requirements, but also to be pleasing to the eye. Regulations may dictate the features and performance of enclosures for electrical equipment in hazardous areas, such as petrochemical plants or coal mines.
One GFCI receptacle can serve as protection for several downstream conventional receptacles. GFCI devices come in many configurations including circuit-breakers, portable devices and receptacles. Another safety device introduced with the 1999 code is the arc-fault circuit interrupter (AFCI). This device detects arcs from hot to neutral that can ...
Arc-Fault Circuit Interrupter (AFCI) protection is required to protect nearly all finished areas of a home with the exception of bathrooms. This device, which can be a circuit breaker or the first outlet on a circuit, is designed to detect hazardous electrical arcing in the branch circuit wiring as well as in cords and plugs.

Care should be taken if Argentinian standards or faulty wiring swaps the active and neutral pins. Care should also be taken with the 10 A version with the round pin as physically compatible, but electrically incompatible NEMA 7–15 connector used for 277 V 15 A connections is encountered in commercial or industrial settings in the Americas.

This is surrounded by a circular shroud on the male connector, which fits into a matching recess on the female connector. The standard defines connectors with 3, 4 and 5 pins, but a non-standard variant with 7 pins (6 in a circle plus one in the centre) is commercially available; [ 6 ] this can be used for star-delta starting of three-phase motors.
