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.

What is best used to mark out the conduits run?
Chalk line is used to mark out the ''conduit run''
What is adequate spacing for supporting rigid metal conduit?
Conduits shall be supported at intervals not exceeding 3000mm.
What size pipe for awg 4?
Conduit is sized by the number of conductors that are being pulled into it. The conduit size of 1/2" will allow one #4 wire to be pulled into it. 3/4" will allow 2 and 1" will allow 4 #4 conductors to be pulled into it.
Is a separate ground wire required for each circuit in a conduit?
Not normally. An elaboration of what circuits are in the conduit and what type of conduit it is would be useful, though, and necessary to give a definitive answer.
Are conduits secured every 5-6 at Electrical service entrance?
Service conduit must be secured every 10 feet and withing 3 feet of a service box.
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.)
How many 10 stranded conductors can you pull in a 1 inch conduit?
Need to know the wire # size to compute wire fill in conduits
What do conduit connectors do?
A conduit connecter is a connecting piece used to connect two individual conduit units together. Conduit connecters can refer to both electrical conduits and pipe/plumbing related conduits.
What kind of conduit can be incasted in concrete?
steel and plastic conduits
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 will happen if an adhesive is used in threads of conduits?
Then you will probably never be able to undo the conduit.
What is the definition of electrical capacity?
The amount of conductors per conduit size example code says 3 number 4 conductors in a 1'' conduit
What size conduit for four 4 cables?
Conduit sizing is based on the number of conductors that are drawn into it. Without the number of 1000 MCM conductors, an answer an not be given.
What is best used to mark out the conduits run?
Chalk line is used to mark out the ''conduit run''
What is adequate spacing for supporting rigid metal conduit?
Conduits shall be supported at intervals not exceeding 3000mm.
Can branch circuits from a panel be pulled in the same conduit if not exeeding the conduit fill requirements?
Yes. The thing that has to be closely watched is the load on the conductors. The conductors will have to be de-rated as the code only gives amperage rating for three conductors in a raceway. So watch the connected amperage to each load and fill the conduit accordingly. This supersedes the conduit fill requirements rule.
What is a conduit?
A conduit is a set of closed canalization circular or not that assures the free passage of conductors and ensures their continuous protection.
