2. Tamperproofing - Wikipedia

   en.wikipedia.org/wiki/Tamperproofing

   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.

3. NEMA connector - Wikipedia

   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).

4. Residual-current device - Wikipedia

   en.wikipedia.org/wiki/Residual-current_device

   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.

5. Tamper-resistant security module - Wikipedia

   en.wikipedia.org/wiki/Tamper-resistant_security...

   A tamper-resistant security module (TRSM) is a device that incorporates physical protections to prevent compromise of cryptographic security parameters that it contains. There are varying levels of protection afforded by TRSMs: Tamper-resistance: make intrusion difficult, usually by employing hardened casing

6. Vandal-resistant switch - Wikipedia

   en.wikipedia.org/wiki/Vandal-resistant_switch

   Tamper-resistant switches (or tamper-proof switches) are types of vandal-resistant switches which are not intended to be operated except by authorized users. They may control special functions, such as auditing of voting machines , operation of power tools or equipment, enabling of security alarm systems (e.g., arming and disarming), or ...

7. Electrical wiring in North America - Wikipedia

   An outlet is defined by the NEC as "a point in the wiring system at which current is taken to utilization equipment". [1] This definition includes receptacles, lighting, motors, etc. Ordinary switches control but do not consume electricity, and therefore are not defined as outlets in this sense.

8. NEMA enclosure types - Wikipedia

   Weather-resistant. Protects against falling dirt and windblown dust, against weather hazards such as rain, sleet and snow, and is undamaged by the formation of ice. Used outdoors on ship docks, in construction work, and in tunnels and subways. 3R: As 3, but omits protection against windblown dust. 3S: As 3, but also operable when laden with ice.

9. AC power plugs and sockets - Wikipedia

   en.wikipedia.org/wiki/AC_power_plugs_and_sockets

   BS 546, "Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50-60 Hz) circuits up to 250 V" describes four sizes of plug rated at 2 A, 5 A (Type D), 15 A (Type M) and 30 A. The plugs have three round pins arranged in a triangle, with the larger top pin being the earthing pin.
