   The following home services are supported by discrete wiring systems: Information and communications Entertainment Energy management Security and safety Digital home health Aged and assisted living Intelligent lighting and power In new home construction, wiring for all electrical services can be installed before the walls are finished.

3. Electrical wiring in North America - Wikipedia

   en.wikipedia.org/wiki/Electrical_wiring_in_North...

   For power circuits, the color-coding uses the same colors as residential construction, and adds the additional wires used for three-phase systems. Black, Red and Blue are used for hot wires and White is used as the neutral wire in a 120/208 V circuit. Brown, Orange and Yellow are used as hot wires and gray is used as the neutral wire in a 277/ ...

4. Aluminum building wiring - Wikipedia

   en.wikipedia.org/wiki/Aluminum_building_wiring

   Depending on the annealing grade, AA-8176 may elongate up to 30% with less springback effect and possesses a higher yield strength (19.8 ksi or 137 MPa, for a cold-worked AA-8076 wire). [citation needed] A home with aluminum wiring installed prior to the mid-1970s (as the stock of pre-1972 aluminum wire was permitted to be used up) likely has ...

   en.wikipedia.org/wiki/Knob-and-tube_wiring

   [4] [citation needed] This direct routing method has the advantage of reduced cost by allowing use of the shortest possible lengths of wire, but the major disadvantage is that a detailed building wiring diagram is needed for other electricians to understand multiple interwoven circuits, especially if the wiring is not fully visible throughout ...

7. Wiring diagram - Wikipedia

   en.wikipedia.org/wiki/Wiring_diagram

   An automotive wiring diagram, showing useful information such as crimp connection locations and wire colors. These details may not be so easily found on a more schematic drawing. A wiring diagram is a simplified conventional pictorial representation of an electrical circuit. It shows the components of the circuit as simplified shapes, and the ...

8. Electronic symbol - Wikipedia

   en.wikipedia.org/wiki/Electronic_symbol

   Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...

9. Twist-on wire connector - Wikipedia

   en.wikipedia.org/wiki/Twist-on_wire_connector

   Twist-on wire connectors are not generally recommended for use with aluminum wire in the United States. [1] The U.S. Consumer Product Safety Commission disapproves wire nuts for aluminum wire; instead, special crimp connectors are called for, and as of 2011 the CPSC asserted qualified, second-preference approval of a certain kind of screw ...
