Ground Neutral and Hot wires explained

Ground neutral and hot wires explained. In this video we look at the difference and purpose of the ground wire, the hot wire and the neutral wire in a north american residential electrical system.

Wiring for AC and DC power distribution branch circuits are color coded for identification of individual wires. In some jurisdictions all wire colors are specified in legal documents. In other jurisdictions, only a few conductor colors are so codified. In that case, local custom dictates the “optional” wire colors.

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 ...

AC Power (120/208/240 Volts) AC power comes in many different types based on how many volts the wires will be carrying. For wires that will be 120, 208 or 240 volts, the following wiring color standards are used.

Today, we are here with another comprehensive Copper and aluminum wire size calculator As we have discussed in detail the topic of “How to calculate the proper wire size for Electrical Wiring. Now you can take the advantage of this calculator to do this job J You can also check the classical Wire & Cable Size Calculator in (AWG) Calculating Wire/Cable Size formula for single Phase Circuits ...

Voltage - Enter the voltage at the source of the circuit. Single-phase voltages are usually 115V or 120V, while three-phase voltages are typically 208V, 230V or 480V. Amperes - Enter the maximum current in amps that will flow through the circuit. For motors, it is recommended to multiply the nameplate FLA by 1.25 for wire sizing.

AC current flows through outer surface due to 'Skin Effect'. Whereas DC current flows throughout the whole cross section diameter of conductor. So DC cable needs Single Strand but AC cable needs Multistranded Copper or Aluminium Conductor bunch fo...

– The calculator allows entry of a voltage drop, but caution should be used when doing so to make sure you are calculating the wire sizes in accordance with NEC article 210-19 (FPN No. 4.) The NEC allows a maximum of a 3% voltage drop on the main branch of a circuit at the farthest outlet of power and 5% total to both feeders and branch circuits to the farthest outlet.

But solid wire is usually easier to secure under screw terminals, such as those found on standard switches and receptacles. In standard usage, though, the wire conductors in conduit or NM cable for household wiring will be 14-, 12- or 10-gauge wire that is a solid copper conductor.

The kit has an impressive high power tone generator which can identify the conductor at a cross-connect point or at a remote end. This kit can be used on single conductors, de-energized AC wiring, coaxial cables and twisted pair wiring.
