If building is serviced with 480 volts and you put a meter between ground and hot what will be the reading?
For alternating current, and assuming the supply transformer is properly grounded, you will have 240 volts to ground. 480 volts; single phase will have Line1 and Line2, both with 240 to ground and 480 across both Lines : three phase will have Line1, Line2, and Line3, all will have 240 to ground, and 480 across any two Lines. Same is true for 240 volt service, 120 to ground and 240 across. 120 volt service is 240 volt service using ground as neutral.

What is the reading ground to neutral?
Ideally ground and neutral should be at the same potential, but as there is current in the neutral wire and no current (normally) in the ground wire there can be a difference. I have personally measured over 25 VAC on the neutral relative to ground in some systems.
Are the neutral and ground bonded in a sub-panel of an out building?
No, in a sub-panel of an outbuilding, the neutral and ground should be kept separate and not bonded together. This is to prevent the potential for ground loops and to ensure proper functioning of the grounding system.
How can the type of ground beneath a building affect the buildings response to seismic waves?
It can affect the strength, durability, or the sturdiness of the building. If the ground beneath it is sand, It is more than likely to fall during an earthquake or something. Sand is a horrible foundation for a building. Loose soil can also affect the building in the same way, making it slide or sink into the ground.
How do you calculate a building footprint?
To calculate a building footprint, you typically measure the length and width of the building's base or foundation. You then multiply these measurements to get the area of the building in square feet or square meters. This calculation provides an estimate of the ground area covered by the building.
How can you read a ground fault using a meter?
To read a ground fault using a meter, you can use a digital multimeter set to measure resistance. Disconnect the ground wire and touch one probe to the ground wire and the other probe to the ground terminal. A reading of 0 ohms indicates a direct short to ground and signifies a ground fault.
Why building foundation have large horizontal area of contact with the ground?
this is because when the area of contact between the ground and the building increases the pressure exerted by the building will be less for the same force.
Why does building foundations have a large horizontal area of contact with the ground?
Building foundations have a large horizontal area of contact with the ground to distribute the weight of the structure evenly and prevent it from sinking or tilting. This helps to provide stability and support for the entire building. The larger the contact area, the more effectively the weight of the building can be spread out, reducing the risk of structural failure.
What is the reading ground to neutral?
Ideally ground and neutral should be at the same potential, but as there is current in the neutral wire and no current (normally) in the ground wire there can be a difference. I have personally measured over 25 VAC on the neutral relative to ground in some systems.
A firefighter places a ladder against a building The ladder forms a 47 angle with the ground What is the measure of the angle between the ladder and the building?
43 degresses
What is the different between basement and semi basement?
One or more floor of a building that are completely below the ground floor is basement. A floor of a building that is half below ground, rather than entirely such as a basement is semi basement.
What is the difference between villa and a condominium?
a villa is ground level. it comes from spanish/mexican for dwelling. a condominium can be on ground level, but is always in a high rise building
What is a camping ground?
A Camping ground is a group of any number of "Camping Sites", grouped together, that are usually serviced and monitored by a business or the state. It usually costs some amount of money to "reserve" a camping site within the camp ground or get "admission" to use the camp ground area. Rules and regulations are different between all camping grounds, so ask the appropriate officials.
What is the standard height requirement for a NEC disconnect in a residential building?
The standard height requirement for a NEC disconnect in a residential building is typically between 5 to 6 feet above the ground level.
Why are buildings built on stilts in Longyearbyen?
So air can pass freely between buildings and the ground. Permafrost exists underground, so if heat from the buildings radiated into the ground and melted it, the ground would sink and the building foundations would be compromised.
How can the type of ground beneath a building affect the building's response to seismic?
It can affect the strength, durability, or the sturdiness of the building. If the ground beneath it is sand, It is more than likely to fall during an earthquake or something. Sand is a horrible foundation for a building. Loose soil can also affect the building in the same way, making it slide or sink into the ground.
What are the reading of dumpy level on staff when you do levels of ground?
When using a dumpy level to determine ground levels, you will record the reading on the staff where the cross-hairs of the level align with the staff. This reading represents the height of the level line above the ground at that point. By taking multiple readings at various points, you can create a profile of the ground levels across the area.
What do you call the support of a building that is usually constructed below ground level?
The support of a building that's usually constructed below ground level is called a basement. Sometimes it is also the "Base" contruction of a building.
