Low-voltage (no more than 30 volts) wiring must be buried at least 6 inches deep. Buried wiring runs that transition from underground to above ground must be protected in conduit from the required cover depth or 18 inches to its termination point above ground, or at least 8 feet above grade.

is it true, how deep is electric line buried?
In addition, National Codes dictate the depth, below ground, these lines must be buried. Some low voltage underground circuits could be as shallow as 18 inches, while most higher voltage circuits will be deeper than 24 inches.
In any case, how deep does Schedule 80 conduit need to be buried? Schedule 80 PVC needs to be buried 18" to meet NEC table 300.5. The depth for PVC can be reduced to 12" with a 2" thick concrete cap (but it's easier to just dig down 6 more inches). Schedule 80 pipe can be connected to structure above ground since you said it was listed sunlight resistant, so that is an option.
In spite of, can Schedule 40 conduit be buried?
Schedule 40 PVC Conduit is used in walls, floors and ceilings in accordance with NEC 352. According to NEC 352 it can also be buried directly into the earth, encased in concrete, and used in areas exposed to direct sunlight.
Can I use indoor wire in conduit outside?
It's important that you follow National Electrical Code (NEC) rules when running an indoor wire through a conduit outdoors. You need to ensure that the conduit is buried deep enough within the ground: 24 in. ... of cover for a PVC conduit, and 6 in. of cover for RMC and IMC conduits.

Originally Answered: How far can you run 12 gauge wire on a 20 amp circuit? About 400 feet. After that voltage drop is a factor and the gauge will have to be increased or the voltage increased.
How far can you run 10 gauge wire for 30 amps? 10-gauge wire is usually used for short 30 amp runs. If you plan on going over 150 feet, 8-gauge wire or thicker will be needed.
The answer: It's possible, but not advisable without an electrician evaluating the situation. You should never just upgrade from a 15-amp breaker to a 20-amp one just because the current one is tripping. Otherwise, you may burn your house down via electrical fire.
RULES OF THUMB “Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps
, and 6-gauge is good for 55 amps,” and “The circuit breaker
or fuse is always sized to protect the conductor [wire].”
The National Electric Code (NEC) sets the required burial depth of electric wire in rigid, non-metallic conduit, such as PVC, at 18-inches. Cable in any conduit, including PVC, that is buried at this depth is not in danger of being severed or disturbed by normal digging.
PVC conduit provides protection for electrical work that is buried underground. ... Among all conduit types, PVC is lightweight and versatile. Available in a variety of thicknesses or grades, PVC is well suited for direct burial or above ground work. PVC conduit is also used for many electrical requirements.
