I think you're asking what size does the grounding electrode conductor need be. This is not determined by the size of the service or your breakers. It's determined in 250.66 by the size of your service conductors. 400A service is typically something like 1000 kcmil aluminum which would require a 4/0 Al or 2/0 Cu GEC.Per Article 250 of the NEC , The minimum size for a grounding conductor for a circuit protected by a 200 amp breaker is #6 copper or #4 Aluminum. This conductor may need to be increased in size for any of several reasons, including the length of the run, available fault current or other reasons that would fill a book.3 Beds, 4 Baths, 5,094 Square Feet, For Sale, $1,599,999 - This property features offers over 5,000 square feet with not a detail spared inside and an outdoor oasis that is truly an entertainer's paradise!

If you have a 320 (400) amp meter base with 2 - 200 amp panels, one on each side usually, then a #2 copper is all you need, however if you are using a meter main panel then 1/0 copper is needed based on the notes to 250.66. Based on power company wire which is 350 kcm then a 1/0 is called for in 250.66 that is 1/0 aluminum. Hambone8780.One opts for a 400 amp service [disconnect]. The ampacity of the service entrance conductors must be 400A or greater. Service drops and laterals are not bound to this requirement, and their ampacity can be determined solely by Article 220 calculations. infinity Moderator. Staff member. Location20 amps require 12AWG. AWG is the preferred means of quantifying wire thickness for most people. Although, if you prefer a different unit of measurement, 12AWG equates to 0.0808 inches (Diameter), 2.053mm (Diameter), and 3.31mm2 (cross-section). 20 Amps Compatibility.The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F).

Re: Parallel Equipment grounding conductor size If this is a 150V-600V wye connected system, then 240.13 applies(it will have ground fault protection). If the ground fault is set to meet 250.122(F)(2) along with meeting the other conditions, then you can use 3/0 egc in each pipe. But why would use use 10 - 3/0 in the first place?The ground wire, often referred to as the grounding electrode conductor, is the link between the ground rod and the service ground connection. Ground wires for residences typically are made of copper and are #6 (6 AWG) or larger. For 200 Amp services, a #4 grounding electrode conductor (ground wire) is required. ….

We do the "400 amp service" also with 2 200 amp panels and a 320 amp meter base. I seen some run 1 #4 to both panels for the water pipe ground. I have also been told you need to run 2 #4 (1 to each panel) or 1 1/0 to both panels. They said you had to add the conductor area together (2 3/0). When I try the math I get 2 3/0=.2790x2=.4580The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F).

cheat room skyrim Here's what I'd do: -go to supplier pull 400A meter base and panel out of their boxes. -check: temp ratings, AL/CU rating, dual vs single lug. -use that info and T2 to choose wire size and parallel vs single run, keeping 12-108 in mind. BTW, a friend of mine priced a job last year based on using AL then. found he could only get a CU rated meter ...Common electrical services include 100, 200, 300, and 400 amps. You need 1¼ inch conduit for 100 amps, 2 inches for 200 amps, 2.5 inches for 300 amps, and 3 inches for 400 amps. The size may differ based on the wire size and the number of wires to put inside the conduit. Multiple factors can affect the conduit size for these electrical services. scottsburg bmvchase bank notarize Parallel conductors are often installed where large ampacity feeders or services are used.
