What size conductors for 3 phase 175 amp circuit breaker 120-208 thhn copper 25' in sch 40 PVC?
A 2/0 copper conductor with an insulation factor of 90 degrees C is rated at 195 amps. It is not stated if this is a motor feeder, if it is, the feeder has to be rated at 125% of the motors full load amperage. If this is a service and the 175 amps is the main disconnect rating then the 2/0 will work fine.
How many amps 8 gauge wire?
A #8 copper conductor with an insulation factor of 60 degrees C is rated at 40 amps, insulation factor of 75 or 90 degrees C is rated at 45 amps.If the breakers rating is 90 degrees C then the amperage can be boosted for 60 degree wire to 40 amps, 75 degree C wire to 50 amps and 90 degree C wire to55 amps.
What is the weight of 500mcm thhn insulated copper cable per foot?
The weight of 500MCM THHN insulated copper cable is approximately 1.002 pounds per foot.
How many amps is a 3 gauge copper wire rated for at 115 volts?
A #3 copper wire with an insulation rating of 90 degree C has the capacity to receive 105 amps. This is the most common or standard insulation that most calculations are based on. It is the insulation that governs the rating of the voltage. House wiring cables are insulation rated at 300 volts. Most other wiring insulation is rated at 600 volts. Special wires have a insulation factor of 1000 volts. The higher the insulation temperature factor is the higher the rating of current through the wire becomes. #3 at 60C is 55 amps, at 75C 65 amps, at 90C 105 amps, at 110C 120 amps, at 125C 130 amps, and at 200C 145 amps.
How many amps 10 gauge wire?
The NEC limits the overcurrent protection of #10 copper to 30A. This means that that a continuous load supplied by the #10 cannot exceed 24A unless the breaker is rated for 100% continuous duty. Don't forget to apply any derating factors as required in table 310.16 of the NEC. For derating you can use the appropriate temperature rating column i.e. 90 deg for THHN dry location but in no case can you exceed 30A. It depends upon What type of wire and how that wire is being run. Standard ratings for residential wiring is a maximum of 30 amps for a #10 wire. To get technical, I think the maximum amperage of #10 wire run enclosed (like in metal conduit) is 33 amps. Most building inspectors will go by the 30 amp rule. 10 copper wire will hold 30 amps /we use this size wire for electrical dryers. For aluminum wiring the maximum loading is lower. 10 gauge aluminum hold 25 AMPS.
What is the current carrying capacity of a 10 gage THHN copper conductor?

A #1 aluminum conductor with an insulation factor of 75 or 90 degrees c is rated at !00 and 115 amps respectively.
Allowable ampacity of 10 copper thin wire rated at 75 degree Celsius?
Isn't it 35, according to the NEC 310.15(B)(16) Table.
If service is fed with service entrance conductors of 500 MCM THHN copper and fused at 400 amps What would be the minimum size of a copper grounding electrode conductor?
For a service rated at 400 amps using 500 MCM THHN copper conductors, the minimum size for a copper grounding electrode conductor (GEC) can be determined using the National Electrical Code (NEC) guidelines. According to NEC Table 250.66, for a service of 400 amps, the minimum size for a copper GEC is 4 AWG. However, if the GEC is connected to a ground rod, it must be a minimum of 6 AWG copper.
What size conductors for 3 phase 175 amp circuit breaker 120-208 thhn copper 25' in sch 40 PVC?

What wire gauge is needed for a single phase 60 amp circuit?
#6 wire is good for 65 Amps as long as it is type THHN.
How many amps 8 gauge wire?
A #8 copper conductor with an insulation factor of 60 degrees C is rated at 40 amps, insulation factor of 75 or 90 degrees C is rated at 45 amps.If the breakers rating is 90 degrees C then the amperage can be boosted for 60 degree wire to 40 amps, 75 degree C wire to 50 amps and 90 degree C wire to55 amps.
What is the ampacity of a No 3 0 THHN copper 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.
What is the amperage rating of 500 MCM copper conductor?
It depends on a lot of factors. Generally speaking, if the insulation is THHN then the rating is 350 amps. If the insulation is THWN then the rating is 310 amps. The ampere rating for wire depends on the temperature of the environment it will be used in, the insulation rating and the number of circuits installed in a conduit. There are also other factors to consider... like voltage drop in long runs.
How many amps will thhn 6 wire carry?
Depends on how far you want to carry that load.For short distances, 6 AWG THHN rated at 90C, used at 30C ambient, is permitted for up to 75 Amps when in a 3-conductor cable or conduit.In free air, it may be "capable" of handling up to 105 amps.NEC Table 310.16 and 310.17.
