MaxineFor an 800 amp service, typically a 3/0 or 4/0 copper conductor or 250kcmil aluminum conductor would be appropriate for the grounding wire. However, it is recommended to consult with a qualified electrician or the local electrical code for specific requirements based on the installation conditions.

What wire size to use from breaker box to earth ground rod?
We recommend using a #6 copper wire for the connection between the breaker box and the earth ground rod. This size wire is commonly used for grounding purposes and is sufficient for carrying the electrical current safely to the ground rod. Be sure to consult with a qualified electrician to ensure the proper materials and installation for your specific situation.
What size ground wire should you use on a 1200 amp service?
For a 1200 amp service, you should use a copper ground wire of at least 3/0 AWG or an aluminum wire of at least 250 kcmil to meet the National Electrical Code requirements. It's always recommended to consult with a licensed electrician to ensure the proper sizing and installation of the ground wire.
What size ungrounded conductor for 800 amp service?
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.
What size conductors are needed for 800 amp service?
For an 800 amp service, typically 4/0 AWG conductors are needed for the hot conductors and 2/0 AWG for the neutral conductor in a 3-phase system. However, it is recommended to consult with a qualified electrician to determine the exact size based on the specific installation requirements and local electrical codes.
800 amp service using parallel sets of 500 cu what size grounding electrode conductor?
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.
