9-10, but the conduit may not exceed a certain length, or a certain voltage in order for you to "legally" do it. Many applications allow for conduit fill ratio's that exceed the standards of the NEC ( National Electrical Code) and most of them are short (less than 24") "chases" between control devices mounted in listed Junction boxes for that purpose. It is not advisable to fill a conduit more than the NEC allows for purposes of heat dissipation.
n you run thhn wire in a cable tray
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.
9 - Is this a test answer or do you just want to know for a project you're doing? Take a look at NEC chapter 9 - tables 4 and 5 (in the 2005 edition at least)
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.
yes
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?
According to the National Electrical Code (NEC), the ampacity of a 4 AWG THHN copper wire at 75°C is 85 amps, and 95 amps at 90°C.
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.

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.
