THHN wire is moisture resistant thermoplastic allowed for use in dry and wet locations. Maximum temperature is 60 C or 140 F. Being thermoplastic it should not be handled below 0 C as cracking of the insulation could easily occur.
Cross link polyvinyl chloride RW90 (PVC) and THHN are two common types of insulation THHN wire stands for thermoplastic high heat resistant nylon coated wire. THWN stands for thermoplastic heat- and moisture resistant nylon coated wire.
The ampacity of a No. 3/0 THHN copper wire, under typical conditions, is approximately 200-230 amps. This value can vary based on factors such as ambient temperature, installation conditions, and whether the wire is in conduit or not. Always consult the National Electrical Code (NEC) or a professional for specific applications.

For a 125 amp circuit using THHN wire, the appropriate wire size would be 1/0 AWG.
The recommended wire size for a 100 amp circuit using THHN wire is typically 3 AWG (American Wire Gauge).
THHN wire is suitable for use in residential and commercial electrical wiring applications, such as powering outlets, switches, and lighting fixtures.
THHN wire is suitable for use in dry and damp locations for general purpose wiring in residential, commercial, and industrial buildings. It is commonly used for power distribution, lighting, and control circuits.

I would need more detailon your question but what i can tell you is 100' of #10 THHN eire is 8320grams with insulation and 7110 grams as bear copper wire. Now what i am trying to figure out is if that copper wire is 100% copper or not?
No, THHN is not oil resistant. The Underwriters Laboratories' (UL) "Marking Guide Wire and Cable (January 2010)" shows that THHN is not sunlight, oil, or gasoline resistant; it can not be used in cable trays, direct burial, or for submersible pumps. THHN is a heat-resistant thermoplastic rated for 90 degrees C (140 degrees F), can be used in dry and damp locations. See related links below for the UL Marking Guide.

The conductor can be pulled into conduit and then buried but it is not certified for direct earth burial.
