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 main reason for connecting a ground wire to the end of a conduit being used to protect the wire?
== == Think about it. The conduit is metal, and can be touched by people. It is carrying live wires and is connected to steel junction boxes. What would happen if a hot wire accidentally touched the steel conduit? The ground wire is there to keep the conduit from going live in a fault condition. You want to ground any metal surface a user can touch in case of faults.
If you have a motor that must remain adaptable to several sizes of belts what is the maximum length of flexible metal conduit you can use before the conduit requires fastening?
Adding an extra length of shaft on the existing shaft to take extra pulleys will put an extra load on the bearings supporting the shaft. In the long term this would shorten the life of the bearings. The makers might be able to supply more information like the side-load specification for the bearings. If in doubt support the outer end of the shaft.
What is rigid metallic conduit?
The metal which does not undergo any kind of deformation under the action of external forces on it is a rigid metal. It will not change in size, shape and position in response to external actions.
One problem when using rigid metal conduit in a residence is that installation of the conduit may?
One problem of using rigid conduit in a residency when it is not needed is that project will very quickly over run the budget of the project. Labour will be at least 5 times more expensive to install rigid over NMD90 cable.Another problem will be the tight bends required in home wiring as compared to the radius bends that rigid conduit requires.
Is 2 ft adequate spacing for the supports for expanded metal for a ATV trailer?
It's okay as long as you never load anything heavier than an standard size ATV.
What are electrical conduit fittings used for?
An electrical conduit is a tube used to protect and route electrical wiring in a building or nonbuilding structure. Electrical conduit may be made of metal, plastic, fiber, or fired clay. Most conduit is rigid, but flexible conduit is used for some purposes.
Does the metal conduit count as a ground?
No, each conduit must contain a separate grounding conductor.
What is metallic conduit?
Metalic conduit is a metal tube that is used to shield wiring from damage, water contamination, contact with people. As opposed to plastic conduit.
Is it better to use metal or pvc conduit?
PVC conduit is better then metal as it won't corrod under ground and theres less of a chance of electrical shortages.
What happens when you drop a magnetic object through a metal conduit?
It will induce a slight (as in negligible and unnoticeable) current in the conduit.
Why should phase and neutral wire be put together in the metal conduit?
to prevent live conduit in case of short circuit
Is it permitted to use flexible metal conduit over 6 ft in length as a grounding means?
is it permitted to use flexible metal conduit over 6 ft in length as a grounding means
What does a 10 foot rigid metal conduit weigh?
depends on size....
Can you run electrical along a metal fence?
Yes, as long as it is in a plastic conduit.
What is RSC in electrical?
In electrical terms it represents Rigid Steel Conduit. It is also known as Rigid Metal Conduit (RMC).This is not to be confused with Electrical Metallic Tubing (EMT) also known in the trade as thin wall conduit.
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.
