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 gold silver copper and aluminum?
The ampacity for copper is 1000A per square inch, in some places is 700A psi.
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.
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.
What is the capacity of 8 gauge wire?
A #8 copper wire with an insulation factor of 75 or 90 degrees C has an ampacity of 45 amps. A #8 wire with an insulation factor of 60 degrees C has an ampacity of 40 amps.

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
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 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 amp size should you use for 2 12s?
The wire ampacity of #12 copper wire with an insulation factor of 90 degrees C is 20 amps. If the load is of a continuous nature e.g. baseboard heaters then the wire has to be de-rated to 18 amps
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.
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 will a number 2 copper wire hold?
Copper wires do not hold amps, they have a cross sectional area capacity to allow amperage to flow. In the electrical trade this is spoken of as "ampacity" of the wire. It is a combining of the two words amps and capacity. A # 2 copper wire with an insulation factor of 60, 75 or 90 degrees C is consecutively rated at 100, 115 and 120 amps.
What is the answer to the analogy fiberglass is to insulation as conduction is to what?
copper
