You do not use a ground wire in the connection from the meter base to the distribution panel. A bonding wire may be required if the service is using PVC conduit.
For a 200amp service you need number 4 copper
You bond the 200 amp service before you call for an electrical inspection. Without this connection the service will not pass and you will not get a connection by the utility company.
Each hot leg to the neutral wire of the service has the ampacity of 200 amps, that is why 3/0 wire is required. A 3/0 copper wire with an insulation factor of 90 degrees C is rated at 210 amps.
If the service pole is only rated for 50 amps, that is all it is designed to handle. The service pole has to be upgraded to handle a home that has a 200 amp entrance panel. Call an electrician and pay for his/her expertise!! Your Family is too important to rely on the advice of a salesperson. I believe your asking how would you add a 50a service pole using your 200amp service? I would highly recommend having a licensed electrician do the work for you as electricity will kill you if you even touched the wrong spot!! Otherwise, You would need all the necessary items from possibly a home improvement ctr and a book on how to do wiring plus all the necessary permits from your town or city etc... (without the proper permits your insurance carrier wouldn't have to pay if a clain were ever made and traced back to your wiring!) Check your 200amp box to see if you have at least 2 empty slots as you'll need at least that many to run that amount of power, 220 volts, Hope this helps a bit.
for USA, Canada and countries running a 60 Hertz supply service.This is a complex question that requires you to do some reading, as it confuses even electricians. The applicable reference is: NEC 220.40 Feeder and Service Calculations.Typically if you are asking this question you should call an electrician to help you. However if you read the applicable NEC article you will be able to calculate your own service.This can be done by using a clampmeter, this is a instrument that clamps over the main incoming cable ( hot wire ) where it enters the distribution board. You set the meter to read amps and this gives you the total amps being used at that time.I always ask the customer to find their electrical useage for the last twelve months. Use the highest month in KWHr, divide that by days in month, then hours in day, then supply voltage such as 240-volts. This will show the highest average ampere demand for which your service conductors are supplying. Don't forget to convert to watts at the end.Surprisingly, most homes average about 10 amps continuous or less. Minimum service rating is 100 amps.If you are paying $.1 per KWHr and the bill is $150 over 30 days, then you used 1500 KWHr, or 8.68 amps per hour continuously on average.You could simply install socket power readers on all the outlets that have electrical appliances attached to them, and that would give you an indication of your power usage. If you wanted to know amps, then that's something else all together.In residential installations, this is usually not a necessary factor to calculate. The utilities companies usually only offer 100 amp, 200 amp or 400 amp service. The typical new home in today's market will use the standard 200 amp service.If you have concerns like having a garage that you will do work in using electrical equipment, then you would want an electrician to calculate the additional load. 200 amp service is quite adequate for most purposes unless you have the aforementioned scenario. My son has a welding shop and business and operates the entire shop with 200amp residential service including a 3 phase generator.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-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
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.
For a 200amp service you need number 4 copper
200 amp service in chicago uses 3 aught.
#6 bare copper wire.
3/0 copper wire with 90 degree insulation is rated at 210 amps. 75 degree insulation is rated at 200 amps.
You bond the 200 amp service before you call for an electrical inspection. Without this connection the service will not pass and you will not get a connection by the utility company.
thanks ,it should be 400amps.
Each hot leg to the neutral wire of the service has the ampacity of 200 amps, that is why 3/0 wire is required. A 3/0 copper wire with an insulation factor of 90 degrees C is rated at 210 amps.
A #4 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 85 amps.
Increasing the ampacity of your service will not cure power drops. If your main breaker has not tripped then your connected load is under 200 amps. The power drops are the responsibility of your utility company. They are required to keep the voltage within a 10% tolerance. When asked some utility companies will connect a recording volt meter to your line to check your claim of low voltage. Call them. Log the time when the power drops over a week. If they will not monitor your line give them the list of the power drops that you recorded as this may help them. You are probably at the end of the line and connections up stream are probably the cause of your power fluctuations.
Not directly, you would need to transform 480v circuit to 120v with a transformer first.
The wires can be as long as they need to be to make the connection. It is a fact that as the length of the wires are increased, the size of the wire also has to be increased, to over come the voltage drop due to the internal resistance of the wire. A 3/0 copper conductor with an insulation factor of 90 degrees C is rated at 210 amps. This is the normal size for a 200 amp service. If the service is further away, then the increasing of the wire size starts at 3/0.
