Best Answer

No, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.

YES


Can you run 110 and 220 volt circuits in the same conduit?

Yes, 120 and 240 volts can be run in the same conduit.


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.)

No


What is the multiplier for 45 degree offset in conduit bending?

Back set for all conduit sizes is not the same. The greater the diameter of the conduit the length of back set increases. Without the diameter size of the conduit, an answer can not be given.

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.


Do you support same-sex marriage?

Yes. I support the removal of legal obstacles that prevent same-sex couples from exercising their basic civil right to marry the person of their choice.


Why 2 different phase wire are not supposed to pass through same conduit?

According to the wording ,2 different phase wires "can" run through the same conduit. Not only can they, but if they are part of the same circuit they must. And in cases where conductors are paralleled, meaning more than one conductor per phase as is common in commercial and industrial installations, you put one conductor of each phase and a neutral, if one exists, and a ground in each conduit. Not doing so, meaning to put all of one phase in one conduit, causes a voltage to be induced into the conduit and a tremendous amount of heat builds up. Even when using pvc or other non-metallic conduit, somewhere along the way you have something metallic and have the same problem. To simplify, you must put all conductors associated with the same circuit in the same conduit.
