A 750 MCM wire with an insulation factor of 90 degrees C is rated at 500 amps. De rated to 80% will allow 400 amps on the wire. A 900 MCM wire with an insulation factor of 75 degrees C is rated at 520 amps. A 1500 MCM wire with an insulation factor of 60 degrees C is rated at 520 amps. Parallel 250 MCM will give you the same usage. A 250 MCM wire with an insulation factor of 75 or 90 degrees C are rated at 255 and 265 respectively. 255 x 2 = 510 x 80% = 408 amps. 265 x 2 = 530 x 80% = 424 amps.
What else can I help you with?
What is the wire size needed to feed a 400 amp service with parallel copper?
It depends on the length of the run
What size wire for 200 amp service?
For a 200 amp service, it is recommended to use 3/0 copper or 4/0 aluminum wire. These wire sizes are suitable for handling the electrical load of a 200 amp service with the appropriate safety margin. It is important to consult with a qualified electrician and adhere to local electrical codes when determining the wire size for a 200 amp service.
What wire size for 70 amp service at 240 volt?
For a 70 amp service at 240 volts, you would typically use a wire size of 4 AWG copper wire. This wire size is suitable for carrying 70 amps of current safely over a 240 volt circuit. Be sure to consult local electrical codes and regulations to ensure compliance with requirements in your area.
What size ground wire should you use on a 1200 amp service?
You need to say whether it's a 150 amp service or a 1200 amp service it has to be one or the other. <<>> A 1/0 copper conductor with an insulation factor of 90 degrees C is rated at 155 amps. There is no ground wire stated for a 150 amp service so the next size up is a 200 amp service. The ground wire for this size is #6 bare AWG. Without knowing what types of loads that are coming off of the distribution a reduced neutral can not be recommended. The neutral will be the same size as the service conductor which is 1/0.
Can you tap off of a 200 amp service for 2 100 amp panels?
Yes, but at every reduction in wire size there has to be a breaker sized to the smaller wire size. The wire size for 100 amp panels is recommended at #3 copper conductor. From the 200 amp feeder panel you will require a 100 amp two pole breaker for each of the two 100 amp services. Keep in mind that if you run the 100 amp services close to maximum this will take away the capacity of the 200 amp service for other branch circuits coming off of it. Also keep in mind that if the panels are located, not in the same building as the 200 amp service that the 100 amp panels will be treated as separate services and will have to be constructed like a 100 amp service. This includes ground rods. Also the bonding screw will have to be removed that connects the neutral buss to the panel enclosure.
