What Wire size for 225 amp commercial panel?
3/0 or250 aluminum
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.
What wire size for 125 amp service?
The short answer, if using copper, is 0 AWG, commonly referred to as 1/0 or "one ought". Type of wire depends on location & temperature, but in my common scenario I am using 1/0 THHN inside a 2" schedule 40 PVC conduit (3 - 1/0 wires plus a 4 ga bare ground) to run indoors, a distance of about 25 feet from my main panel to a sub for upstairs. I could go into more detail regarding outdoor, direct burial, grounding, aluminum wire, etc but would need more details.
What is the ampacity of an ACSR?
WIRE AMPACITY TABLE ACSR DIA.(OUt) CCC 795MCM 1.093" 900 A 556.5MCM 0.927" 730 A 336.4MCM 0.721" 530 A 4/0 0.563" 340 A 3/0 0.502" 300 A 2/0 0.447" 270 A 1/0 0.398" 230 A 2 0.316" 180 A 4 0.250" 140 A 6 0.198" 100 A
Can you double up on insulated wires for greater ampacity?
According to the 2008 National Electrical Code, the smallest wire that can be run in parallel is a 1/0 AWG (American Wire Gauge). If the wire you are using is smaller than a 1/0 AWG, you will need to increase the size of the wire to handle the amperage (Table 310.16 of the NEC).
What size copper wire is equal to 0 aluminum?
#1 copper thhn
What wire size for 100 amp sub panel 250 ft from main panel?
1/0 copper thhn covering. 3/0 aluminum again thhn covering
What Wire size for 225 amp commercial panel?
3/0 or250 aluminum
What cable for 150 amp Service Entrance Cable?
200 amp service entrance wire should be AWG # 2/0 copper or 4/0 aluminum.
Can you run two 60 amp sources in parallel to get 100 amps out?
No they can not, because the electrical code states that wires in parallel can only be 1/0 AWG and larger. The ampacity of 1/0 wire is 150 amps. The ampacity of a wire for 60 amps is #6 which is much smaller that 1/0 wire.
In a residential 200amp service is 100 amps the maximum that each of the two phase conductor can transmit or can they both carry 200 amps?
Each hot leg to the neutral wire of the service has the ampacity of 200 amps, that is why 3/0 wire is required. A 3/0 copper wire with an insulation factor of 90 degrees C is rated at 210 amps.
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.
What gauge of electric wire needed for a 160' run at 125 amps?
A 2/0 copper conductor will limit the voltage drop to 3% or less when supplying 125 amps for 230 feet on a 240 volt system.
What is the weight of 3-0 copper wire per foot?
what is the weight of 300 MCM Copper wire
What gauge wire for 100 amps?
120/240 single phase dwelling NEC 310.15(B)(6) #4 copper or #2 Al otherwise, NEC 310.16 #3 copper THHN or #1 Al THHN 2/0 Aluminum. <<>> A #3 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 100 and 115 amps respectively. A #1 aluminum conductor with an insulation factor of 75 or 90 degrees c is rated at !00 and 115 amps respectively.
What size copper wire should you use for 240 volts 200 amps?
3/0 wire 3/0 wire
