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.

∙ 7y agoI have never heard of the electrical term intimated conductor. Conductors are rated on their insulation factor. The number that is stamped on the conductor's insulation is the maximum ambient temperature that the conductor can be submitted to. Most home building cables are rated at 75 and 90 degrees C.

What is the difference between thhn and romex?
THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor. Romex is a brand name for a nonmetallic sheathed cable, it has multiple conductors inside, the insulated ones are insulated with THHN insulation.
Is THHN oil resistant?
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.
Five 8 aluminum conductors with THHN insulation are to be routed through a conduit found in a boiler room with an ambient temperature of 75 degree C. What would be the ampacity of each conductor?
#8 aluminum thhn 90 degree wire is rated at 30 amps. Remember to de-rate the wire for more that three conductors in a raceway and the second de-rate for the ambient temperature. Most students miss the de-rate for more that three conductors in a raceway.
Can you run 8 gauge thhn wire for 30a circuit?
yes
What size copper wire is equal to 0 aluminum?
#1 copper thhn
What is the temperature rating of THHN WIRE?
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.
How does temperature affect power rating of carbon resistors?
Its normal power rating is at room temperature. For a temperature of 75 degrees, halve the rating.
Can you run thhn conductors exposed?
n you run thhn wire in a cable tray
What is the difference between thhn and romex?
THHN is a heat resistant thermoplastic insulated conductor, usually a single conductor. Romex is a brand name for a nonmetallic sheathed cable, it has multiple conductors inside, the insulated ones are insulated with THHN insulation.
The rating T130 on a transformers label?
I think this refers to the continuous temperature rating, which is the maximum rated winding temperature allowed for a maximum ambient air temperature of 40deg C.
Can you operate a transformer below kva rating?
What limits the use of a transformer is its operating temperature, as excessively-high temperature will act to break down its insulation. The temperature reached by a transformer is a function of its rating (expressed in volt amperes), so operating a transformer below its rating is perfectly okay.
What is the ampacity of each five no 8 aluminum conductors with thhn insulation being routed through a conduit with ambient temperature of 75 Celsius?
School question. The answer can be found in your electrical code book.
