2. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   Rigid nonmetallic conduit (RNC) is a non-metallic unthreaded smooth-walled tubing. Electrical nonmetallic tubing (ENT) is a thin-walled corrugated tubing that is moisture-resistant and flame retardant. It is pliable such that it can be bent by hand, and is often flexible although the fittings are not.

   The conduit methods were known to be of better quality, but cost significantly more than K&T. [2] In 1909, flexible armored cable cost about twice as much as K&T, and conduit cost about three times the price of K&T. [6] Knob and tube wiring persisted since it allowed owners to wire a building for electricity at lower cost.

   This type of cable is the least expensive for a given size and is appropriate for dry indoor applications. The designation NM XX-Y indicates, respectively, the type of sheathing (in this case, non-metallic), the size of the main conductors, and the total number of circuit conductors (exclusive of the grounding conductor). For example, NM 14-2 ...

   en.wikipedia.org/wiki/Electrical_wiring

   Insulated wires may be run in one of several forms between electrical devices. This may be a specialised bendable pipe, called a conduit, or one of several varieties of metal (rigid steel or aluminium) or non-metallic (PVC or HDPE) tubing. Rectangular cross-section metal or PVC wire troughs (North America) or trunking (UK) may be used if many ...

6. National Electrical Code - Wikipedia

   en.wikipedia.org/wiki/National_Electrical_Code

   The NEC specifies acceptable numbers of conductors in crowded areas such as inside conduit, referred to as the fill rating. If the accepted fill rating is exceeded, then all the cables in the conduit are derated, lowering their acceptable maximum ambient operating temperature. Derating is necessary because multiple conductors carrying full-load ...

   Once they reached their final standing position, however, Amabile placed his arms on either side of Johnson's waist and began to spin her in a cartwheel, but once she rotated 180 degrees, her body ...
