What size is the grounding electrode of a 400 amp service 500CM?
In Canada the grounding electrode requirement is for two steel 5/8" x 10' copper clad rods spaced 10 feet apart.
What size copper grounding electrode conductor is required for a service that has three sets of 600 kc mil copper conductors per phase?
The grounding conductor of a service distribution is sized by the ampacity of the service. By just stating the wire size, this does not give this information, as many variables enter into what wires are used depending on length, ambient temperature and insulation factor to name a few.
What size romex for 60 amps of service?
A 300 MCM copper conductor with an insulation rating of 90 degrees C is rated at 320 amps. Parallel the feeders to obtain a total of 640 amps. This will be acceptable as service feeders for a 600 amp service.A 400 MCM aluminium conductor with an insulation rating of 90 degrees C is rated at 305 amps. Parallel the feeders to obtain a total of 610 amps. This will be acceptable as service feeders for a 600 amp service.
How to ground and bond a panel?
It must be grounded outside with two 8' copper ground rids driven fully into the ground. One under the meter and one 6' to either side connected together with the proper size copper ground wire. The above answer leaves out the requirement for a grounding connection to a metal water pipe. The NEC actually makes the ground rods supplemental to the water pipe. We don't usually consider the water pipe as the primary grounding electrode but that is how it is treated in the code. Depending on the size of your service, the grounding electrode conductor to the water pipe may actually be a different size than what connects to the ground rods, which are allowed to be connected with 6 AWG copper regardless of the size of service.
What is an grounding electrode conductor?
It is the conductor that is used in service distribution panels that bonds the distribution panel's neutral bus bar to the ground electrode (rod). This brings all of the distribution panel neutrals that are connected to the same supply system to the same potential, that being zero. Should a supply service neutral open this ground wire will maintain the systems integrity until repairs can be made.
For a parallel feed to a 1200 Amp service 3 phase what size is the grounding electrode to main service with 3 600 mcm parallel runs?
500 mcm
What size is the grounding electrode of a 400 amp service 500CM?
In Canada the grounding electrode requirement is for two steel 5/8" x 10' copper clad rods spaced 10 feet apart.
If you have a 400 Amp service using 500 MCM What size grounding electrode conductor is required?
#2
800 amp service using parallel sets of 500 cu what size grounding electrode conductor?
The size called for is one ought (0). There are addendum to this rule depending on where you live in the country. Check the addendum to this code rule in your area.
What size service ground is needed for a 350 parallel service?
From the question it is hard to establish whether the service size is 350 amps or the service conductors are 350 MCM in parallel. If the service is 350 amps, the grounding conductor is #3 bare copper wire. Parallel 350 MCM conductors will allow for a 600 amp service. The grounding conductor for a 600 amp service is a #1 bare copper wire.
How many ground rods are required for a 200amp service in Indianapolis?
According to the NEC, if the ground rod supplements another grounding electrode such as a metal water pipe, you are required 1. If the ground rod or rods is your only grounding electrode, you are required at least 2, at least 6 feet apart. Check with your local jurisdiction for local requirements.
How do you find a good online tranlater?
Grounding Electrodes and Grounding Electrode Systems All grounding electrodes present at a building or structure must be bonded together to form a grounding electrode system, as required by NEC® Section 250.50. Doing so eliminates voltage gradients, and also improves reliability and grounding performance over time by creating redundancy. If one electrode is damaged, destroyed by corrosion, or removed, other electrodes are available to maintain the all-important connection from the service equipment to ground. Section 250.53(B) states that two or more grounding electrodes effectively bonded together are considered a single grounding electrode system. Permitted Electrodes The NEC recognizes the following seven types of grounding electrodes [250.52(A)]: Metal underground water pipe Metal frame of a building or structure Concrete-encased electrodes Ground ring Rod and pipe electrodes Plate electrodes Other local metal underground systems or structures (piping, tanks, well casings, etc.)

What should the clearance be from service entrance panel to grounding material?
grounding material is not a good word but as short as possible is a good answer the entrance panel must be connected to the best possible ground this is called the grounding electrode the grounding electrode conductor connects to the ground bar in the entrance panel if the panel has a a neutral the neutral bar can be bonded to the ground bar Grounding electrodes form best to worse well casing water pipe (NOT plastic) buried plates or wire grid or bonded reinforcing steel driven rod if you are talking about distances to the panel it should be centered about shoulder height doors need to have about 2' of clearance in all directions weather open or shut
Iec 60502 2xfgy 61kv xlpe can you use the armour as grounding conductor?
NO some armored cable has a ground some sealtite has copper in the helix wit the drain shield some liquite has no conduction at all all armor is a helix which is a coil and acts as insulation at hi frequency xlpe cross linked polyethylene is an insulator service cable is never used for grounding grounding electrode conductor grounding equipment conductor grounding conductor are all separate from service cables if a tall trucks hits an overhead cable you dont want to lose the ground in short NO
Do you have to have a safe and efficient grounding system?
It is an electrical code requirement that every service must have a grounding system.
