A 350 MCM aluminum conductor with an insulation factor of 90 degrees C is rated at 260 amps.
The conductor can be pulled into conduit and then buried but it is not certified for direct earth burial.
Wire size determines how much current can be safely conducted. Insulation type and rating determines other factors, such as where the wire can be used and maximum voltage. It should be noted that the high voltage lines that are hanging from the really large electrical towers are among a class of wires that have NO insulation around the outside of the wire. They are instead, connected to the towers with large insulators that prevent electrical energy from being lost through the towers.
The frequency has no direct relationship to the size of wire. Wire is sized as to the amount of current a load draws in a circuit.
No, it is not possible to run Romex wire directly underground in a basement. Romex wire is not rated for direct burial underground and should not be used in this application. Instead, you should use UF-B (underground feeder) cable or conduit with appropriate wiring for underground installations.
you need to test it with a multi meter, set on the right settings. if you knew the voltage you could get an appropriate light bulb to suit the voltage and put that across the wire to test if there is current.

The current rating of an 18AWG wire is typically around 16 amps.
The current rating of a 10AWG wire is typically around 30-40 amps.
The current rating of an 18 AWG wire is typically around 16 amps.
The maximum current rating for a 20A wire gauge is 20 amperes.
The maximum current rating for an 18AWG wire is typically around 16 amps.
For a 100 amp service installation, you should use a type of direct burial wire called "Type UF-B" wire.
The maximum current rating for a wire that can safely handle 10 wire amps is 10 amps.
The maximum current rating for an 18 AWG wire is typically around 16 amps.
For a 100 amp direct burial installation, it is recommended to use copper wire with a minimum size of 3/0 AWG (American Wire Gauge) or larger. Copper wire is preferred for its conductivity and durability in underground applications.
The maximum current rating in amps for a 10 AWG wire is typically around 30 amps.
Wire in conduit for underground feeders has to have an insulationrating for wet and damp locations. In the marketplace there is also wiring thathas an insulation rating for direct burial that does not need to be installed into conduit.
