2. Electrical conduit - Wikipedia

   en.wikipedia.org/wiki/Electrical_conduit

   Liquidtight flexible metal conduit (LFMC) is a metallic flexible conduit covered by a waterproof plastic coating. The interior is similar to FMC. Flexible metallic tubing (FMT; North America) is not the same as flexible metallic conduit (FMC) which is described in US National Electrical Code (NEC) Article 348. FMT is a raceway, but not a ...

3. Bonding jumper - Wikipedia

   en.wikipedia.org/wiki/Bonding_jumper

   [2] Some codes require a bonding jumper to be pulled into non-metallic conduit or in electrical metallic tubing that may be exposed to corrosion or mechanical damage. In North American electrical codes, an important bonding jumper is found in main electrical panels, where the system neutral conductor is connected to earth ground. This must be ...

4. Electrical wiring in North America - Wikipedia

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

   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 ...

5. Copper conductor - Wikipedia

   en.wikipedia.org/wiki/Copper_conductor

   This is an essential property in electrical wiring systems. Copper has the highest electrical conductivity rating of all non-precious metals: the electrical resistivity of copper = 16.78 nΩ•m at 20 °C. The theory of metals in their solid state [7] helps to explain the unusually high electrical conductivity of copper.

6. Power cable - Wikipedia

   en.wikipedia.org/wiki/Power_cable

   This metallic shield can consist of a thin copper tape, concentric drain wires, flat straps, lead sheath, or other designs. The metallic shields of a cable are connected to earth ground at the ends of the cable, and possibly locations along the length if voltage rise during faults would be dangerous. Multi-point grounding is the most common way ...

7. Corrugated stainless steel tubing - Wikipedia

   en.wikipedia.org/wiki/Corrugated_stainless_steel...

   The most common CSST is a type of conduit used for fuel gas distribution in buildings. It has a flexible corrugated stainless steel inner layer and an outer yellow or black plastic jacket. Yellow-jacketed CSST was developed first and is the most common. It has a non-conductive plastic yellow jacket. Black-jacketed CSST is relatively new.
