Wiring Definition and 169 Threads

Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure.
Wiring is subject to safety standards for design and installation. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals.
Associated circuit protection, control and distribution devices within a building's wiring system are subject to voltage, current and functional specification. Wiring safety codes vary by locality, country or region. The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards amongst member countries, but significant variations in design and installation requirements still exist.

    How Is a Power Recliner Wired for Multiple Functions?

    As far as I can tell there are three circuit states that control the recliner foot rest, raise it, lower it, and off. How is this wired, how does the switch function etc...? I assume the up and down switch flip the polarity across the motor, but that is all I can seem to reason out...

    Why Does Changing Wire Gauge Affect Voltage and Current in a Generator?

    I am building a small generator. 12 - 5/8″ magnets rotating around 9 - 3/4″ diameter, 28-gauge copper enameled wire. Not under load, I am getting 50 volts at 1 amp. But when I increase the wire size to 24-gauge, I am getting 15 volts at .25 amps. I thought amps go up when volts go down.

    Electrical Load Cell Wiring Length Question

    I would like to weigh our pet parakeets. They are rather skittish, so the idea I came up with was to hack a digital scale so as to put the controls and display some distance from the scale. Then I would add a perch to the scale. When one of our birds lands on the scale, I could turn on the...

    How are the connectors on the DC linear actuator utilized in wiring?

    A am working on a project that uses this 12V DC linear actuator. The actuator utilizes a magnetic coil and plunger inner design (I believe this is just a solenoid). This actuator will need to use both directions of movement for the project. In terms of wiring, what do the two female connectors...

    Hard Wiring of Animal Behaviors

    I often hear that a certain behavior of an animal is "hard wired". I get the analogy, but what does that really mean in the brain? What two things are "wired" together and what is the actual "wire"? If a dog runs after a squirrel (dogs are of course "hard wired" to chase squirrels), are his eyes...

    I What is the Role of Superconductors in Lossless Wiring and Power Transmission?

    Zero resistance in wiring seems to be the technology in the future. Any resistance in the transmission wiring acts like loads so it's like the current wastes itself on the resistances in the wiring and heat that occurs. So lossless wiring seems to be the ultimate goal. In Large Hadron Collider...
