14-2 W/G NM-B Wire White Non-metallic sheathed NM-B cable is used in normally dry installations in residential wiring, as branch circuits for outlets, lighting and other residential loads. Its applications are outlined in NEC 2008 and NEC 2011 Article 334.

Also used for wiring of machine tools (stranded), ap- pliances, and control circuits not exceeding 600 volts. STANDARDS: 1. Listed by UL as Type THHN or THWN per Standard 83, and as Type MTW per Standard 1063 (stranded items). ... Listed by UL as Sunlight Resistant (1/0 AWG and larger, black only).

16mm is roughly AWG 5. Extrapolating that each change in AWG of 1, at that end of the scale, 5AWG wire can carry 62.5 amps at 60 degrees C If copper. Aluminum is 47.5 amps at the same temperature.

The difference between pins and k-wires is mainly diameter: IM pins—also referred to as Steinmann pins—are between 1.5 mm (1/16 inch) and 6.5 mm (1/4 inch) in diameter, while K-wires are 0.9 to 1.5 mm (0.035, 0.045, 0.062 inches) in diameter.

A weber per square meter (Wb/m²) is a unit of the magnetic flux density, commonly denoted as B, equal to tesla. A particle carrying a charge of 1 coulomb and passing through a uniform magnetic field of 1 tesla at a speed of 1 meter per second perpendicular to the said field experiences a force of 1 newton.

2/0 AWG will handle around 190 amps, whereas 2 AWG will handle around 94 amps. This is slightly misleading as the length of the wire must also be considered and the % voltage drop acceptable. For a 3% drop where the load is 20 feet from the battery and you are drawing 100 amps then you would need 2/0.

The conductors are type THHN. All are wrapped with a polypropylene (plastic) assembly tape and an outer aluminum interlocked armor. (This cable should not be installed in damp locations or areas exposed to sunlight.) NM-B is used for general indoor circuit wiring in locations that are normally dry.

One nanometer (1 nm) is equal to 10-9 m or 0.000000001 m. A nanometer is 10 times smaller than the width of your DNA, and 10 times bigger than the size of an atom. Even though nanoscale is very small, it is at least 109 or 1,000,000,000 times bigger than a quark. Quarks are really, really, really small.

Indicate whether boron atoms are paramagnetic or diamagnetic. Answer: The B atom has 2s22p1 as the electron configuration. Because it has one unpaired electron, it is paramagnetic.

The solid conductor THHN wire has a solid copper conductor and its American Wire Gauge (AWG) is sized 14-10. The stranded conductor THHN wire, on the other hand, has an AWG size of 14-4/0 and stranded conductor of 19 copper strands. The aluminum conductor is not made of soft hardened copper but with aluminum.

14 grams of nitrogen is equal to 1 mol of elemental nitrogen. There would be 6.02 × 10^23 atoms of nitrogen.

The most common gauges are 10, 12 or 14. Larger numbers represent smaller sizes or gauges of wire. Tip: If a project calls for longer lengths of wire (such as 80 or more feet from the breaker), increase the gauge size to ensure that enough electricity can pass through it.

NM is usually labeled by the gauge of the conductors and the number of conductors in the assembly. Regardless of the manufacturer, a label includes the wire gauge and the number of insulated wires. For instance, 12/2 NM has two insulated 12-AWG conductors housed in the outer jacket along with an uninsulated ground.

1 nm corresponds to 3x10^17 Hz. For comparison, the equivalent figures for ultra-violet light are 100 nm, 3x10^15 Hz and 1.2 Kev.

Wire thickness is identified by its American Wire Gauge (AWG) number. The lower the gauge number, the thicker the wire. Thicker wire presents less resistance to current flow. ... Thick wire (12 or 14 gauge) is recommended for long wire runs, high power applications, and low-impedance speakers (4 or 6 ohms).

(This cable should not be installed in damp locations or areas exposed to sunlight.) NM-B is used for general indoor circuit wiring in locations that are normally dry. It may be used for both exposed and concealed work and may be fished (pulled) through wall cavities.
