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 is the smallest size of a common grounding electrode conductor installed for multiple separately derived systems?
3/0 awg wire
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 of grounding electrode for 1200 amp service with 3 500 kcmil feeders in parallel?
Hi ,my name isBob,and i want to know what is the minim amperage required for one commercial space 1020.00 sq Ft ? is going to be like an restaurant. Very respectfully, Bob
What size grounding conductor is needed for a 80 amp service?
For service sizes of 100 amps and less a #8 bare copper conductor is required.
If you have a 400 Amp service using 500 MCM What size grounding electrode conductor is required?
#2
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

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.
What size grounding conductor is needed for a 80 amp service?
For service sizes of 100 amps and less a #8 bare copper conductor is required.
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.
Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
What size ground wire for a 400 amp panel in Quebec?
This answer is taken from the CEC. Table 17 states minimum size of grounding conductors. For a service conductor drawing 400 amps a #3 copper grounding conductor is needed. Also see rules 10-206, 10-700 and 10-812 if you have access to the code book.
