2. Junction box - Wikipedia

   en.wikipedia.org/wiki/Junction_box

   A small metal, plastic or fiberglass junction box may form part of an electrical conduit or thermoplastic-sheathed cable (TPS) wiring system in a building. If designed for surface mounting, it is used mostly in ceilings, concrete or concealed behind an access panel—particularly in domestic or commercial buildings [2].

3. NEMA enclosure types - Wikipedia

   en.wikipedia.org/wiki/NEMA_enclosure_types

   Below is a list of NEMA enclosure types; these types are further defined in NEMA 250- Enclosures for Electrical Equipment. 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 ...

4. Distribution board - Wikipedia

   en.wikipedia.org/wiki/Distribution_board

   A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.

5. Electrical enclosure - Wikipedia

   en.wikipedia.org/wiki/Electrical_enclosure

   An electrical enclosure is a cabinet for electrical or electronic equipment to mount switches, knobs and displays and to prevent electrical shock to equipment users and protect the contents from the environment. The enclosure is the only part of the equipment which is seen by users.

6. Automotive fuse - Wikipedia

   en.wikipedia.org/wiki/Automotive_fuse

   As the fuse element melts, it creates a high resistance to reduce the magnitude and duration of the current flowing through the fuse to protect the electrical circuit and connected equipment. [17] Frequently, these are used in close proximity to starter battery fuse boxes. They are used also in electric vehicles, e.g., in forklift trucks.

7. Electrical junction - Wikipedia

   en.wikipedia.org/wiki/Electrical_junction

   An electrical junction is a point or area where (a) two or more conductors or (b) different semiconducting regions of differing electrical properties make physical contact. [1] Electrical junctions types include thermoelectricity junctions, metal–semiconductor junctions and p–n junctions. Junctions are either rectifying or non-rectifying.
