When paralleling a service must the sets of conductors be in separate conduits or can they be in the same conduit?
It is common practice to run paralleled sets of conductors in separate conduits to ensure proper current sharing and to reduce the risk of electromagnetic interference. However, they can be run in the same conduit as long as the conduit is sized appropriately to accommodate all the conductors and complies with local codes and standards.
Are conduits secured every 5-6 at Electrical service entrance?
Conduits are typically secured at multiple intervals along the length of the conduit, usually every 3 to 5 feet depending on local building codes and requirements. Inspections are conducted to ensure that the conduits are properly secured and supported at the electrical service entrance to prevent damage and maintain safety standards. It's best to consult with a licensed electrician or building inspector for specific regulations in your area.
What is the minimum size of service conduit?
Answer for USA, Canada and countries running a 60 Hz supply service.Conductors should not be smaller than #8 copper. With that that in mind a 1" conduit would work. Better to use at least 1 1/2-2" depending on the amps of your service. Bigger is always better!As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can you have only one current carrying conductor in a conduit?
Yes, a conduit can accommodate only one current-carrying conductor, provided it meets the installation requirements outlined in the National Electrical Code (NEC) to prevent overheating and maintain safety standards. Conductors should have sufficient space within the conduit to dissipate heat and prevent insulation damage.
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.
Does the metal conduit count as a ground?
No, each conduit must contain a separate grounding conductor.
When paralleling a service must the sets of conductors be in separate conduits or can they be in the same conduit?
It is common practice to run paralleled sets of conductors in separate conduits to ensure proper current sharing and to reduce the risk of electromagnetic interference. However, they can be run in the same conduit as long as the conduit is sized appropriately to accommodate all the conductors and complies with local codes and standards.
When exist a junction box EMT conduit must be supported with how many inches?
When exist a junction box EMT, conduit must be supported within 18 inches.
Can a three phase circuit be installed in the same conduit or in different conduits?
The conductors of any three phase circuit must be run in the same conduit. If the circuit requires a neutral, it must also run with the conductors in the same conduit. (If they were to be run in more than one conduit or raceway, the circuit would not operate properly.)
Can multiple feeders be in same conduit?
Yes they can. If the feeders are of different sizes, then a conduit fill calculation must be made to ascertain that the conduit does not become overfilled. Cross sectional areas of the conductors are found and it is then determined what the conduit cross sectional fill will allow.
Can you run insulated wires in a conduit pipe?
Except for the ground wire they must be insulated.
Are conduits secured every 5-6 at Electrical service entrance?
Conduits are typically secured at multiple intervals along the length of the conduit, usually every 3 to 5 feet depending on local building codes and requirements. Inspections are conducted to ensure that the conduits are properly secured and supported at the electrical service entrance to prevent damage and maintain safety standards. It's best to consult with a licensed electrician or building inspector for specific regulations in your area.
Do you need a mast to run aerial wire from a garage with a 100 amp fuse box to an office trailer?
Yes, it must have a standoff, and the proper service head in. I would run it underground instead of overhead. Use underground wire in a conduit.
What is the code for strapping EMT conduit from a box?
The 2008 NEC code states that conduit must be strapped within 36" or 3 feet from every box or connector, then every 5 feet is acceptable from there.
To use gadgets they must be attached to the windows taskbar?
CIS 5.2 Brooklyn College, correct. They must be attached to the Sidebar!!
What is another name for thin wall conduit?
Another name for thin wall conduit is EMT (Electrical Metallic Tubing). It is a type of conduit made of steel that is commonly used for protecting and routing electrical wiring in commercial and industrial construction.
