For an 800 amp service with parallel sets of 500 kcmil copper conductors, the grounding electrode conductor size should be based on the largest conductor in the parallel set. The grounding electrode conductor size should be sized based on Table 250.66 in the NEC, which recommends a minimum size of 3/0 AWG copper for 1/0 AWG or larger service-entrance conductors.
A 3/0 copper conductor would allow you up to 100 feet at 800 Amps with only 5 percent voltage drop, assuming 240-volt service. If it were a 3-phase 480-volt service, you could go more than 23 feet with only a 5 percent drop. <<>> The size of conductors for an 800 amp service could be sized in several ways. Using a single conductor is out of the question as the size will be impossible to bend or handle. A 2000MCM wire only has a rating of 775 amps. Most high amperage services will use parallel runs to add up to the required amperage. A parallel run of 600 MCM will give you a total of 910 amps. A triple parallel run of 300 MCM will give you a total of 885 amps. A quad parallel run of 3/0 will give you an amperage of 840 amps. The key here is to find the most economical way of installing the service. Take into account the availability of triple barrel or four barrel lugs, wire costs for the larger sizes and the labour to man handle the larger sizes into the main switch. These size services that I have installed, the customer opted for the four barrel lugs with 3/0 wire. The 3/0 wire is a readily available item even though the lugs may have to be a special order.
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.
The size of a garden needed to feed a family of 4 depends on the types of crops grown and the family's dietary needs. On average, a garden of about 600-800 square feet can provide enough fresh produce to supplement a family's diet. However, this can vary based on factors such as crop selection, gardening practices, and climate.
The wire size used in a service entrance distribution panel is governed by the size of the services over current device. The larger the service, the larger the fault current could be, the larger the ground wire to carry the fault current to ground. If the largest service conductor carries 100 amps use a #8, 200 amps - #6, 400 amps - #3, 600 amps - #1, 800 amps - 1/0 and over 800 amps - 2/0 for the ground wire. <<>> Golden Valley Electric Assoc. in Alaska requires #4AWG copper wire for a ground from the breaker box to earth ground rod. The same goes from the service entrance panel on the pole.
For a 3-phase 800 amp service, the conductor size will depend on various factors, including the type of conductor (copper or aluminum), the installation method, and ambient temperature. Generally, for copper conductors, you might need around 3/0 AWG to 250 kcmil, while for aluminum conductors, sizes typically range from 250 kcmil to 400 kcmil. It's essential to consult the National Electrical Code (NEC) and local regulations for precise sizing based on specific conditions and to ensure safety and compliance. Always consider factors like voltage drop and temperature ratings in your calculations.
For an 800 amp service with parallel sets of 500 kcmil copper conductors, the grounding electrode conductor size should be based on the largest conductor in the parallel set. The grounding electrode conductor size should be sized based on Table 250.66 in the NEC, which recommends a minimum size of 3/0 AWG copper for 1/0 AWG or larger service-entrance conductors.
