What gauge wire do you need for a water ground for a 600amp service?

Answer for USA, Canada and countries running a 60 Hz supply service.
The answer is 3/0 copper or 250 kcmil aluminum and requires that the METAL water pipe have at least 10ft of its length in direct contact with the earth. Using a METAL water pipe as a grounding electrode also requires a supplemental electrode, which is most commonly one or more ground rods.
This is NOT the way most 600A services are grounded and I recommend you consult a licensed electrician in your area to determine what is commonly done in your area.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

How do you ground a 200 amp service with no water main?
You need two forms of grounding according to the code. Grounding to the water main is typically the best ground in a building. If you don't have a water meter you can add an extra ground rod.
What size cold water ground for a 200 amp residential service?
#4 bare copper connected to two 8' copper ground rods 6" apart driven into the ground.
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 size ground wire to water meter for 400 amp service?
You need 2 ground rods of 8' in length. One under the meter base and another one 6' to either side of the meter base. Drive them into the ground with just enough sticking up to connect the ground wire.
What size ground wire for cold water pipe for 325 amp service?
DON'T CONNECT A GROUND WIRE TO A COLD WATER PIPE!!! Use ground rods in accordance with local codes. When in doubt, contact a local electrician or the local building and zoning office of your city or county. Connecting a ground wire to your cold water pipe can result in electrolysis that will eat away at you water pipe. ---------------- Metal underground water pipe is the first grounding electrode listed in the NEC. It is still commonly used in residential installations and is used in commercial installations when available. When the water pipe is used as the primary grounding electrode, it must be supplemented with another electrode which is most commonly a ground rod. Generally speaking, a 325 amp service requires 350 kcmil copper conductors for residences or 400 kcmil copper conductors for commercial installations. In either case these require a grounding electrode conductor of 1/0 ("one ought") copper.
Why is the rain gauge buried in the ground?
The rain gauge should be buried in the ground to prevent it from being toppled.The rain gauge should be placed in the buildings as the heat causes the water collected to evaporated.
Why do the rain gauge stand at about 30cm above the ground?
It stands at 30 cm above ground to prevent water from splashing into it from the ground.

What size wire to ground water pipe?
For a 200amp service you need number 4 copper
Picture of a water temperature gauge on 96 Saturn sl1?
Try searching for 96 Saturn sl1. The photos should have some dash shots and show the gauge. You can also check a service manual for the picture.
What size cold water ground for a 200 amp residential service?
#4 bare copper connected to two 8' copper ground rods 6" apart driven into the ground.
Is water table and ground water the same?
Similar, the water table is where we find ground water, ground water is simply water in the ground
How do you repair a 1986 Mazda B2000 water temperature gauge?
More than likely the gauge is NOT the problem.Just make a jumper wire and disconnect the sending unit wire from the water temperature sender and place one end in the connector and ground it to the block and the gauge should work or show say hot.If it does show the gauge show the needle in the hot it is the sender is faulty and should be replaced.If the gauge does show the needle move to hot and moves to the cold it will be the gauge is bad(not likely in most cases).Have a helper in the truck to turn the key to the ON position not running when you ground the sending wiring to the block to note wether it moves up to hot or down to cold when you do this to simplify the issue.I will bet the sending unit for the water temperature is just worn out most of the time.
What is water that soaks into the ground called?
The water that soaks in ground called as ground water .
How does a water gauge works?
To answer you question more thoroughly I will need more detail because there are several different types of water qauges. You have a water temperature gauge, water pressure gauge and water level gauges.
Why farmers use rain gauges?
They simply use water gages to see how much water is in the ground. It depends on which water gauge you are talking about, it could be the reason i just stated or to see how much it is going to rain, or how much water is below the surface.
What is the water pressure needed for a 6 story building with 30 families?
For water to "climb" 10 meters from ground, there must be 1 ATM. So for 6 story building with aprox. 2.6 m per store, there must be 1.56 ATM water pressure at ground. The volume of water consumed depends on gauge of pipes and debit of pumps.
