No, the utility company wants nothing but the service wires in the service stack. Another weather head can be installed to accept your cable and telephone service positioned adjacent to the service stack. If underground service a separate conduit to the comunications pull box will be needed.

When paralleling a service must the sets of conductors be in separate conduits or can they be in the same conduit?

They can be either separated or combined. What governs the choice is the size of the service and the conductors feeding the service and the ability to physically connect metering equipment to larger size conduits. When paralleling conduits make sure all the phase wires are in their individual conduits to cancel the field effect of the wires. Eg. conduit 1 - L1 + L2 + N , conduit 2 - L1 + L2 + N. Likewise with three phase, conduit 1 - L1, L2, L3, conduit 2 L1, L2, L3.


Can you put two wires in one conduit and two wires in another conduit of the same circuit?

No, each conduit should only contain wires from the same circuit. Mixing circuits in a conduit can lead to interference and safety hazards. It is always best practice to keep conductors of the same circuit together to prevent potential issues.


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.


Can you have only one current carrying conductor in a conduit?

You can have only one current carrying conductor in a conduit, but that conduit must have a slot to relieve the eddy currents that will be created by the transformer effect created by the conductor. It is better to run the neutral or opposite conductor along with the hot conductor together in the same conduit, or through the same penetration, so as to minimize this effect.


What are some examples of a tee joint in the electrical trade?

A tee joint in the electrical trade is a conduit fitting. It is used in conduit work where there needs to be a device connected into the main conduit run. An example of this is where a light switch needs to be installed into the conduit run. The main conduit run starts at the distribution panel and proceeds to a lighting fixture. On the way a switch is needed to operate the light fixture. In the main conduit run a tee fitting is installed so as to pick up the switch for the fixture. When the conduit system is complete the wire is then drawn in. The "hot" conductor is pulled to the tee fitting and then diverts to the switch box to pick up the switch and then back up the same conduit to the tee fitting and then on to the lighting fixture. Splices are not usually made in tee fittings.

Is it legal to support a conduit from another conduit of the same size?

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.

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 you mix line and load in same conduit?

No


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.)

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.


Can you run parallel 4 ought aluminum conductors in the same 4 inch conduit?

Yes. Actually they should be run in the same conduit. You don't ever want to run parallel separately.


Does coaxial cable give more cable than white cable?

no there about the same one's just white


Can you run different phases in the same conduit?

No, you cannot run different phases in the same conduit. In electrical systems, different phases must be kept separate to prevent interference and ensure proper functioning of the system. Mixing phases in the same conduit can lead to imbalanced loads, increased heat generation, and potential safety hazards. It is important to follow electrical codes and standards to maintain the integrity and safety of the electrical system.
