What size electrical wire is required for 20 amp breaker 275 feet away?

Would probably go with 10 gauge since 12 would do normally, a 275' length is a long run. Voltage drop would be a concern, especially if the load of the device had a high start up demand. Air conditioner, refrigeration unit, air compressor, etc.

To answer this question correctly a voltage must be given, since sizing the wire is all about voltage drop over a distance.

For a 20 amp circuit at 275 feet, you should use at least a 10 gauge copper wire to minimize voltage drop and ensure safety. This size wire will help maintain the proper voltage levels over the distance. Be sure to consult your local electrical code and a qualified electrician for specific requirements and installation guidelines.

Exterior electrical service wires should be at least 3 feet away from?
Exterior electrical service wires should be at least 10 feet away from swimming pools to prevent any potential hazard.
Exterior electrical service should be 3 feet away from what?
Windows that can be opened.
Is 10-3 wire heavy enough for a washer-dryer combination if they are 50 feet away from the breaker box?
No, for a 50-foot run from the breaker box, 10-3 wire is not heavy enough for a washer-dryer combination. It is recommended to use 8-3 wire for this distance to ensure safe and efficient electrical supply for the appliances.
How far should exterior electrical wires be from windows?
Exterior electrical wires should be a minimum of 3 feet away from windows to prevent potential hazards like accidental contact, electrical shock, and interference with window operations. It is also recommended to consult local building codes for specific guidelines regarding wire placement near windows.
What is the maximum height allowed in CA for the circuit breakers New panels the meter sits physically lower than the heighest breaker and as such the top breaker if the meter is 6 tall is even?
In California, the National Electrical Code (NEC) typically requires a minimum of 6 feet and 7 feet clearance in front of and above electrical panels, respectively, for safety and accessibility. However, local regulations and building codes may have specific requirements that vary. It is best to consult with a licensed electrician or the local building department for precise guidelines in your area.
How many feet away does the electrical box have to be from the actual meter?
It has to be at least eighty feet away Not it has to be fifteen

Can a meteorite of some size on impact give off an electrical charge enough to effect a cars electrical system at 1000 feet away?
No, a meteorite impact would not produce an electrical charge large enough to affect a car's electrical system 1000 feet away. The amount of energy released upon impact would likely be insufficient to cause such interference at such a distance.
Is 10-3 wire heavy enough for a washer-dryer combination if they are 50 feet away from the breaker box?
No, for a 50-foot run from the breaker box, 10-3 wire is not heavy enough for a washer-dryer combination. It is recommended to use 8-3 wire for this distance to ensure safe and efficient electrical supply for the appliances.
What is the minimum distance required by code that a vent needs to be away from an air intake?

How much loss from power pole to 200 amp breaker box then off 400 feet then split at a pump house then another 30 feet to a 100 amp breaker box?
The loss of voltage over a distance depends on factors such as wire gauge, current flowing, and resistance. For a 200-amp service at 400 feet and then branching off another 30 feet to a separate 100-amp service, there could be a noticeable voltage drop. It is recommended to consult with a licensed electrician to calculate the exact voltage drop and determine if any voltage compensation measures are needed.
