What is the ampacity of gold silver copper and aluminum?
The ampacity for copper is 1000A per square inch, in some places is 700A psi.
What size copper grounding electrode conductor is required for a service that has three sets of 600 kc mil copper conductors per phase?
The grounding conductor of a service distribution is sized by the ampacity of the service. By just stating the wire size, this does not give this information, as many variables enter into what wires are used depending on length, ambient temperature and insulation factor to name a few.
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 size of parallel wire for 900 amp service?
Conductors by code are only allowed to be loaded up to 80 percent. In this case an over size wire set will be higher that what the wire is rated for in the code book. A 600 MCM copper conductor with an insulation factor of 90 degrees C is rated at 455 amps. Paralleled together will give an ampacity of 910 amps. After the derate the maximum amperage allowed is 728 amps. So to get the full 900 amp the wire size has to be increased to a 1000 MCM copper conductor with an insulation factor of 90 degrees C which is rated at 585 amps. Paralleled this give you an ampacity of 1170 amps. After the derate the maximum amperage allowed is 1170 x 80% = 936 amps
What is the ampacity of a 10 sq mm Aluminium wire?
A 10 mm squared conductor is equal to a #8 AWG. A #8 copper conductor with an insulation factor of 75 or 90 degrees C are both rated at 45 amps.
What is the ampacity of gold silver copper and aluminum?
The ampacity for copper is 1000A per square inch, in some places is 700A psi.

How many amps does 4 0 copper hold?
A 4/0 copper wire can typically carry about 230-260 amps of current. The actual ampacity can vary depending on factors such as installation method, temperature, and insulation type. It is important to consult the National Electrical Code (NEC) or a licensed electrician for specific ampacity ratings.

Amp capacity of 10 gage copper wire?
in most circumstances the ampacity of a 10 awg wire is 30 amps but should not be loaded to more than 80% of its capacity as a rule of thumb. there are certain instances were these values can change but like i said under "normal" conditions 30amps
Calculate copper losses at 75c?
Copper Loss at 75 C = Copper Loss at Ambient Temperature C * (310/(235+Ambient Temperature C))
What is the ampacity of a NM-B cable?
Allowable ampacity for 10-2 copper NM-B is 30 A.http://www.cerrowire.com/default.aspx?id=46
The ampacity of a number 12 aluminum wire with rhw insulation installed in a raceway that has 19 other wires is?
A #12 copper conductor with an insulation factor of 90 degrees C is rated at 20 amps. A #12 aluminium conductor with an insulation rating of 90 degrees C is rated at 15 amps. These conductors ratings only applies to three conductors in a raceway. To apply the derate to the conductor requires the size of the raceway. From 7 to 24 conductors in a raceway, both aluminium and copper conductor's ratings have to be reduced by .70, so 15 amps x .7 = 10.5 amps and 20 amps x .7 = 14 amps respectively.
What is the ampacity of a 10 sq mm Aluminium wire?
A 10 mm squared conductor is equal to a #8 AWG. A #8 copper conductor with an insulation factor of 75 or 90 degrees C are both rated at 45 amps.
What is the capacity of 8 gauge wire?
The capacity of 8 gauge wire is typically around 40 amperes for general household electrical wiring. It could vary based on factors like insulation type, installation method, and specific application requirements. It's important to consult local electrical codes or a professional electrician to ensure proper usage.
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.
How many amps can a 2.5 sq mm wire conduct?
It will taken 8 amps <<>> The conversion of 2.5 sq mm wire to AWG is equal to a #12 wire. The ampacity of a #12 copper wire with an insulation factor of 90 degrees C is 20 amps.
