What gauge of cooper service wire for 200A service to meter box and service panel?
bed
Can a 200A 240V house panel be fed by number 2 conductors from a service entrance meter panel with 200A main breaker?
Absolutely not. #2awg conductors are only good for about 100 amps depending on Cu or al. see nec table 310-16.
Can you add 100 amps to 200 amp ratred box?
No, if the UL Rated Listing for the Panel is 200A than that's it. You cannot have 300A flowing through a 200A Panel.
Can a 30 K W gas emergency generator support a 200 amp residential service with a voltage config of 220 120 volts?
Need to know what voltage the generator is outputing. The maximum voltage a 15kW generator will support at 200A is dependent on service voltage and configuration, the rated generator voltage, the power factor and the load frequency. If this is a typical service to a residential unit, eg. 220V single phase, then the generator will not be able to safely support 200A.
If you have a 200A Meter Main Combo do you need a main 200A breaker in the panel?
When I went to a 100 amp service I could not find a 100 amp. breaker in stock. I used a 60 amp. breaker and have never blown it. The 200 amp you are using can handle up to 200 amps, but if you use a smaller breaker it will only handle up to that amperage. The 200 amp is usally the total amperage of all the breakers comming out of the box. You will probably never come anywhere near using 200 amps at one time.
What gauge electrical wire is required to upgrade your electircal service to 200A if your incoming service is underground?
4/0 Aluminum or 2/0 Copper type USE.
What gauge of cooper service wire for 200A service to meter box and service panel?
bed
What is the minimum size alluminum ground for a 200A service?
250 mcm
What size cable is used for house wiring?
Copper SE cable gauge 00 from the meter socket to the breaker panel for a 200A service. Then 8, 10, 12, and 14 gauge wire depending on the load.
Can you run a service line from your existing 200A service 150 feet to a 40A service in your barn?
As long as you do it according to local code, there's no electrical problem with it.
What size aluminum wire for a 220v 200a service in conduit undrreground at 180 ft?
250 MCM aluminum minimum
Can a 200A 240V house panel be fed by number 2 conductors from a service entrance meter panel with 200A main breaker?
Absolutely not. #2awg conductors are only good for about 100 amps depending on Cu or al. see nec table 310-16.
What is the estimated cost of upgrading from 60A panel and replaced with a new 200A service?
Doing it yourself or hiring an electrician? Yourself: About $300. An Electrician: About $2000
What is maximum continues current rating of motor?
200A
200a composite number or a prime?
200 is composite.
Can you add 100 amps to 200 amp ratred box?
No, if the UL Rated Listing for the Panel is 200A than that's it. You cannot have 300A flowing through a 200A Panel.
If you have a 200A service panel is it true that you actually have 400A because you have two legs because your breakers add up to more than 200A?
The short answer to your question, is "yes" if you are talking about 120 volts. The panel is rated 200A @ 240v. In reality, service panels should be rated in watts (or kilowatts) We are charged by watts and we use electricity in different combinations of volts and amps, but watts remains a constant. (hence the reason we are charged by that value) So, as you noted, there are two legs, that each pass through a pair of interconnected 200 amp breakers. With 240v appliances, power is tapped from each leg, so at no time can 200 amps be exceeded. But with 120v appliances, power is tapped from one leg and terminated to the neutral leg. It is possible to draw a total of 400 amps from both legs, to the neutral. (actually, it's more complicated than that, as the neutral would never see more than 200 amps, and power is actually being routed in series between loads of each leg, so in reality it's still only a max 200A at 240v)So, for further clarification, let's get back to the watts thing. Watts can be calculated mathematically. Watts = volts X amps. So 240v times 200A equals 48,000 watts. That is your service panel's rated wattage. Now, the math can be reversed. 48,000 watts divided by 120v equals 400A.A simple way to present the question would be, "Could you have twenty 20 amp single pole circuit breakers at full load in a 200A service panel?" The answer would be, "yes."
