Does the metal conduit count as a ground?
No, each conduit must contain a separate grounding conductor.
When is it permissible to wire tie a wire to a conduit?
What kind of wire? If it's a power wire, why is the place wired with conduit? Commercial buildings must put all power wiring in conduit, so if you're planning to run romex in a commercial building, the answer would be "no", it's not permissible. If it's data wire, note that there may be some "crossover" interference if the data wire follows a power wire for very much distance. It's usually not a problem to cross a conduit and tie to it, but it's generally recommended that you not tie data cable to conduit.
Does triplex wire need to be in conduit under a house?
Yes. If they are single wires they need to be in a conduit.
Does the Nec allow grounding electrode conductor to be run in conduit that has other conductors in the conduit and what code section?
No, the bare copper grounding conductor can not be in a conduit with other conductors. It can be in conduit by itself to provide mechanical protection for the wire.
How is wire pulled into a conduit of 100 feet?
A 100 foot fish tape and wire lubrication will be needed to make this wire pull.

What is conduit wirimg?
Conduit wiring is simply wiring that you find in a conduit. Typically, a conduit is a small round tube, usually metal but sometimes plastic, that carries wires from one area to the next. Wire has a tenancy to sag and get tangled and such when it is laid out in long distances. The conduit serves to protect the wire and to ensure it stays linear and it stays in place.
Is a separate ground wire required for each circuit in a conduit?
No, a single ground wire can be used for multiple circuits in a conduit as long as it meets the sizing requirements based on the largest circuit conductor in the conduit. The ground wire provides a path for fault current to safely return to the source in case of a fault or short circuit.
Why should phase and neutral wire be put together in the metal conduit?
to prevent live conduit in case of short circuit
What is the difference between one current carrying conductor in a conduit and a hot and switch leg in a conduit?
In the first part of the question there will be only one wire in the conduit, in the second part of the question there will be two wires in the conduit.
Is it permitted to use flexible conduit over 6 feet in length as a grounding means?
No. The new electrical code change does not allow any flexible conduit to be used as a ground means. It is now required to have a green ground wire pulled into the conduit with the other conductors in the flexible conduit. This grounded bonding conductor is not counted as wire fill when calculating the size of the flexible conduit to use
Does the Nec allow grounding electrode conductor to be run in conduit that has other conductors in the conduit and what code section?
No, the bare copper grounding conductor can not be in a conduit with other conductors. It can be in conduit by itself to provide mechanical protection for the wire.
What size conduit for 400amps?
The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.

What are synonyms of conductor?
transmitter, wire, channel, conduit, director, pilot
