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.
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.
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.
To split one circuit into two branch loads within a junction box, connect the hot wire from the circuit to a wire nut and then connect two separate hot wires to the wire nut, each leading to its own branch load. Repeat the same process for the neutral and ground wires, ensuring proper connections and wire terminations.
For a 60 amp circuit, a 6 gauge wire is typically used as the neutral wire. This wire size ensures proper grounding and safety for the circuit. Make sure to always consult the National Electrical Code (NEC) and local codes for specific requirements in your area.
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, the conduit has to be supported individually from a supportive structure. The spacing of the strapping is related to the size of the conduit.
When two different phase wires pass through the same conduit, there is a risk of inductive coupling between the wires. This can lead to interference and distortion of the electrical signals, potentially causing malfunctions or damage to the electrical system. Additionally, having two phase wires in close proximity can increase the likelihood of short circuits or electrical faults. It is important to follow proper wiring practices to ensure the safety and efficiency of the electrical installation.
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.
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.
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?
If they are on the same circuit you only need 1 neutral wire in the circuit.

Yes, 120 and 240 volts can be run in the same conduit.
Traveler wires are used in a three-way electrical circuit to connect two switches that control the same light fixture. They allow for the switches to work together to turn the light on and off from different locations. The traveler wires carry the electrical signal between the switches, allowing for communication and coordination in the circuit.
