The following refers to supply service conductors. No attachment point shall exceed 30 feet. Across highways, streets, lanes and alleys not less than 18 feet. Across driveways to residential garages not less than 14 feet. Across driveways to commercial and industrial premises not less than 16 feet. And across ground accessible to pedestrians only not less than 11 feet. Primary conductors clearances are; 2.5 to 23 Kv clearance is 20 feet, 34.5 Kv clearance is 22 feet, 46 Kv clearance is 23 feet, and 69 KV clearance is 25 feet.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.
IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
No, the ground wire should be attached to the green or bare copper wire. The black wires are typically live or hot wires and should never be connected to the ground wire.
The ground wires should not be terminated on the neutral bus. They should be terminated on to the ground bus which should be located on the back wall of the distribution panel. The wires don't have to be pigtailed when inserted into the ground bus. More that one wire can go under the terminal screws if you are running out of room. Shut the panel off and remove any ground wires that are now under the neutral bus terminals and move them to the ground bus. Some panels use a lug for a ground bus. All ground wires into the lug and tighten. In a ground fault condition it is the ground wires that are connected to the ground potential that trip the breaker, not ground wires connected to neutrals. Be safe.

In home wiring, hot wires are typically colored black or red, while ground wires are usually green or bare copper. In computer wiring, ground wires are typically black, while hot wires are often colored according to industry standards, such as red or yellow.
If you are connecting a 4-prong dryer cord to a 3-prong outlet, the extra ground wire (green or bare copper wire) should be left unconnected. Do not try to ground it by connecting it to the neutral terminal or anywhere else. This is to prevent creating a ground loop and potentially causing a safety hazard.
Check ground wires... and all connections.

No! check with your power company.....
When installing outdoor electrical wire above ground, it is important to take safety precautions such as using weatherproof materials, ensuring proper grounding, avoiding overloading circuits, and following local building codes. Additionally, wires should be protected from physical damage and installed at a safe height to prevent accidental contact. It is recommended to consult a licensed electrician for proper installation and safety measures.
No, ideally there should be no voltage between the neutral and ground wires in an electrical system.
There should be no reason to install two ground wires in the same conduit. Code requires that only a single path should be required if it is to carry a fault current. This ground wire should be single and continuous from the device back to the distribution panel. It is the fault current that is carried on the ground wire that trips the breaker or fault protection device. Don't confuse grounding wires with bonding wires.
There should be 2 or 3 wires. A hot, a neutral and sometimes a ground.
ten feet or more is a nice distance.

The NEC doesn't specify. Generally they are installed vertically with the ground on bottom. In the world that I work in the ground is always installed on top. This is so if a gap exists between an outlet and the plug, anything falling into the gap hits the ground first and not across the hot and neutral wires simultaneously. Expanding on this premise an outlet installed horizontally with the neutral on top is the most safe installation. But I have never seen this done.
Yes, any flexible conduit that has live wires drawn into it must have a ground wire also installed with the "hot" conductors. The reasoning behind this rule is that the flex in the conduit is coiled and has a long length to it. The continuation of the grounding medium through the tightness of the conduit connectors to the flex was not considered a properly secured grounding system so to overcome this weakness in the grounding system, a ground wire now has to be installed.
