What else can I help you with?
Do you have to encase rigid and PVC conduit in concrete that has high voltage wires from a transformer?
If you are talking about the primary wires to the transformer then yes they have to be encased in concrete.
What is the difference between one current carrying conductor in a conduit and a hot and switch leg in a conduit?
In the first part of the question there will be only one wire in the conduit, in the second part of the question there will be two wires in the conduit.
If a light bulb is connected between 2 wires and both wires have 300 volts of electrical energy is the light bulb lit?
A light bulb connected between to wires, each having 300 volts to ground that are in phase, will not light, because there is no differential voltage available to do any work. If each wire has 300 volts to ground and are out of phase (600 volts between them) the light bulb will be lit, if it is rated at least for 600 volts, otherwise it will burn out.
Is voltage drop across each device the same in household circuits?
No, even though these are parallel circuits, the voltage drop across each device is not the same in house hold circuits, or anywhere, for that matter. Different devices pull different currents. A toaster, for instance, pulls many times what a light bulb pulls. Since wires do not have truly zero resistance, those differing currents result in different voltage drops across the wires that lead to the devices. That small voltage drop in the wires results in a different voltage drop across each device, even though the device/wire is connected to the same voltage source.
How did we use wire to make our voice travel?
Wire is made of metal which conducts electricity. Run a pair wires a fair distance and put a voltage on it, (say from a battery) at one end. The voltage can be detected at the other end. Now, if we can make the voltage vary in time with the vibrations from our voice, the same variations can be detected at the other end. In the early days the voltage was changed by running the voltage through a carbon microphone. The sound pressure waves on a diaphragm compresses the carbon and alters the resistance and hence the voltage on the wire. Now we need a way to turn this varying voltage back into sound. This was done using an electromagnet. At the receiving end the wires are connected to a fine wire wrapped around an iron pole. The varying magnetic force can be used to attract a metal disc, which as it moves also moves the air and sound is heard.This of course is an over simplification. The success is in the fine tuning of the device at each end, to do the job effectively and make it work. These days electronics is used to amplify the signal, make it louder, clearer and travel further. Sensitive mirophones are used to pick up the slightest sound, with the aid of more electronics.
Do you have to encase rigid and PVC conduit in concrete that has high voltage wires from a transformer?
If you are talking about the primary wires to the transformer then yes they have to be encased in concrete.
What type of conduit is used for 480 volt 3-wire?
Conduit is just a medium to get the wires from one place to another. There is no voltage restrictions in low voltage wiring (750 volts or less). When it comes to conduit fill, electricians are governed by the electrical code conduit fill tables. The conduit is sized to accommodate the conductor size for a specific load.
How many wires are typically accommodated in a PVC conduit according to the "How Many Wires in PVC Conduit" chart?
The "How Many Wires in PVC Conduit" chart typically accommodates up to 9 wires in a PVC conduit.
When do you derate wires in conduit I know the code says more than 3 current carrying conductors but is there a length of conduit run when you should start to derate?
There are two things here to keep in mind. If you are trying to add more conductors to an existing conduit run use the cross sectional area of the conduit to see if more wires can be fitted. The second thing that's relates to length is the voltage drop at the load. To size the conduit work backwards from the load amperage to size the wires. If a long distance is involved a voltage drop calculation will be needed. Then select the conduit size to accommodate the wires recommended for that load amperage. The length of conduit run is not brought into the equation on de rating wire size it is always about keeping the voltage up at the load end of the run by increasing the wire size and selecting the proper conduit size for that wire.
What are the best practices for installing low voltage conduit in a residential setting?
When installing low voltage conduit in a residential setting, it is important to plan the layout carefully, use appropriate materials, follow local building codes, and ensure proper grounding. Additionally, it is recommended to label the conduit for easy identification and to leave some slack in the wires for future maintenance.
What is the purpose of a conduit sweep in electrical installations?
A conduit sweep in electrical installations is used to smoothly change the direction of a conduit without sharp bends, reducing the risk of damaging the wires inside and making it easier to pull wires through the conduit.
How many 12/2 wires can fit in a 3/4 conduit?
In a 3/4 conduit, you can fit up to three 12/2 wires.
What information does the conduit wire fill chart provide for determining the appropriate amount of wiring that can be safely installed in a conduit?
The conduit wire fill chart provides information on the maximum number and size of wires that can be safely installed in a conduit based on the conduit's size and type of wires being used.
Does triplex wire need to be in conduit under a house?
Yes. If they are single wires they need to be in a conduit.
What information does the conduit wire capacity chart provide for determining the maximum number of wires that can be safely installed in a conduit?
The conduit wire capacity chart provides information on the maximum number of wires that can be safely installed in a conduit based on the wire size and type of insulation.
What information can be found in the wires in conduit chart?
The wires in conduit chart provides information on the types and sizes of wires that can be safely installed in different types of conduit. It includes details on wire gauge, insulation type, and maximum current-carrying capacity for each wire size.
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.
