What size neutral for 60 amp circuit?
what kind of circuit? if it's a subfeed from one panel to another same size as hot wires. if it's a straight 240 volt circuit #8. depends on what kind of circuit.
Can you run coaxial in the same PVC conduit as the electric service?
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.
What will happen if someone only connect one of the wires to the bulb holder?
If someone only connect one of the wires to the bulb holder, the circuit will be open and the lamp will not light. This is the same principal that a switch in the circuit does. It opens and closes the circuit.
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.
Does the short or long wire get hottest in a circuit?
This will depend on the circuit configuration, and the wire. For two equivalent types of wire (same covering, thickness, cross section, but different lengths) in a series circuit, where the surrounding on both wires is kept equivalent, heating will be equal per unit length (meaning the wires will reach the same temperature); The longer wire will use more power, which will cause more room heating (due to the longer length), but the wires themselves will reach the same temperature. For the same two wires in a parallel circuit, the smaller wire will heat up more due to a larger current flow through it, thus a higher I^2 * R loss (heat loss) per unit length. If two wires are put in parallel, and have different lengths, but are made to have the same resistance, the exact same amount of current will flow in each, but the shorter one will inherently have a higher resistance per unit length, causing it to become hotter than the longer wire.
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 you put low voltage sound wires and low voltage light wires in the same conduit?
noyou can not
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.
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 two 2 pole single phase circuits in the same conduit?
Yes, this only adds up to four wires. The wire sizing is dependant on the amperage of the two single phase loads. Remember to calculate the conduit fill of the four wires to make sure that you have the correct size conduit for the installation.
What kinds of accessories are used in full conduit wiring?
If the conduit has reached its limit as to how many wires can be in it, there is only one course of action and that it to install another conduit parallel to the existing one. The electrical code book only allows a certain cross sectional filling of any conduit size. The rule is based on the dissipation of heat from the conductors in the circuits through the conduit walls. Once the wire fill has reached that figure no more wires should be pulled in because of insulation heating. Over time the heating of the insulation could lead to insulation breakdown and then short circuiting of the existing conductors that are in the same conduit.

Can you use existing PVC conduit run from basement to 8th floor for 120v circuits for chillers?
The simple answer to your question is yes. But there are limits to how many wires can be in any conduit, and the current carrying capacity of the conductors can be affected by distance, ambient temperature, and how many conductors are contained in the same conduit. Other things to consider are, Can you physically fit the wires in there? Would it be easier to run a new conduit? Do you have the manpower necessary to get the work done?

How many neutral wires are needed for lighting and outlets?
If they are on the same circuit you only need 1 neutral wire in the circuit.
