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.

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.
Are elec main breaker boxes predetermined on how many 15amp and 20amp breakers you can install in the number of slots?
No. If you look at your current main panel and look at the size of the mail breaker you might have 200A or so. Then if you add up all the breaker amperage ratings you will likely exceed the main breaker value. This is because the design of the various circuits takes into account the normal load on each circuit and expects that duty factors of each circuit will not be constantly at the maximum values. If you had a clamp-on amp meter you could easily determine how each of the current breakers was loaded under various circumstances.
Is it possible to run 2500 feet of underground cable from one 200A breaker box to another 200A breaker box without a power loss?
According to voltage drop calc.you would need to run a 900mcm cable min. for 200 amp 240 volt Every cable has loss because every cable has resistance. It is basic physics.

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.
What should you do if your 200A breaker panel is full and you need to add three forty amp two pole singal throw breakers?
First you need to determine if addition of the new breakers will exceed the 200A service under normal operating conditions. If so you will need to go to power company and increase service and put in a larger main panel. If you have the capacity for the extra current you can add a sub-panel and add the breakers there as well as the breakers you will remove from main panel to accommodate the sub-panel breaker. Another way depends on what breakers are in current panel. There are some breakers that can be duplexed in the same space as a single breaker.

How much does it cost to move an electricity meter?
The meter is typically installed in the main circuit panel of the house. If you want to move it, you can do it as part of a service / panel upgrade. We did this when we moved into our new house - we replaced the 1950s vintage main circuit panel and 100A service with a newer 200A panel and service. It was about a grand, but we didn't actually move the panel from where it was, so it may cost more for what you want.

What cause the Main Breaker trips when I start a 30KW 3-phase Motor(Star Delt Starter)?
The wiring is like this:[[30KW Motor ---- Star Delt Starter(100A Breaker inside) ----- 200A Breaker------50A Breaker(Inside the breaker box which located inside the factory) -----100A Main Breaker]]Once I try to start the Motor, the Main Breaker trips immediately.

Considering 100A 240V service has 2 poles at 100A each is the total usable power actually 200A at 120V?
No, amperage is not additive, but a constant. Think of power as water, its always the same temperature, hot (amps). The pressure is variable (volts). The true answer is undoubtedly more complex, but you get the point. If you need to draw 200 amps you would actually need a 400 amp service because code states you cannot have more than an 80% load on a breaker That's an interesting question and I had to run the theory through my brain a few times to confirm my answer. The answer is if you have a 100A 240V service, you could draw what appears to be 200A from that panel at 120V. If you install 100A 120V single pole breakers on each side of the panel (in reality this would be many breakers but let's keep it simple) then both breakers will operate just fine, giving the appearance of 200A. In reality, however, one breaker actually feeds through to the other breaker. The neutral only carries the unbalanced load so in this hypothetical situation the neutral at the panel carries 0A. So the answer to the question is...if you install ONLY 120v single pole breakers, you can run up to 200A on those circuits (or 80% of that as we have discussed.) But you are only running 100A on each leg of the service conductors and breaker.
If you have a 200A supply with 10 breakers totaling 160A on one leg and 10 totaling 205A on the other can you install a dual 15A breaker on the first leg to add a heated floor with 800 watts?
breaker values aren't additive
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
