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 else can I help you with?
Can a 200A 240V house panel be fed by number 2 conductors from a service entrance meter panel with 200A main breaker?
No, number 2 conductors are not sufficient to carry 200A. You would need larger gauge wires to safely handle that amount of current. It is important to match the wire size to the amperage rating of the panel to prevent overheating and potential hazards.
How many KVA is needed for a 200A panel?
To determine the KVA needed for a 200A panel, you can use the formula KVA = (Voltage x Amperage)/1000. Assuming a standard voltage of 120V, the KVA would be 24 KVA (120V x 200A / 1000 = 24 KVA).
What gauge of cooper service wire for 200A service to meter box and service panel?
For a 200A service, the recommended copper wire gauge for service entrance cable is typically 2/0 AWG (American Wire Gauge). This wire size is able to handle the ampacity required for a 200A service safely and efficiently. It is always recommended to consult with a licensed electrician to determine the appropriate wire size for your specific installation.
Are elec main breaker boxes predetermined on how many 15amp and 20amp breakers you can install in the number of slots?
No, the number of 15-amp and 20-amp breakers you can install in a main breaker box is determined by the box's overall amperage capacity and size. Check the box's specifications and consult with a licensed electrician to ensure proper installation and safety.
How many breaker and what size breakers can i use in a 200 amp service?
The rating of a main breaker panel has no direct relationship to the "cumulative total" of the ratings of its installed breakers. Any such notional direct relationship or "limit" is totally immaterial and misleading and could be the cause of serious misunderstandings about the way a breaker panel can be fitted with circuit breakers.Put in very simple terms, because the branch circuits in an installation are unlikely all to be fully loaded during any period of time, the wiring codes and regulations allow the total number of breaker-amps to exceed the maximum total rated amps of the breaker box, but how to decide how much that excess can be is something professional electrical engineers and licensed electricians learn how to calculate and assess as part of their detailed professional training.For more information see the answer to the Related Question shown below.The maximum total amperage that can flow from the panel's main breaker to all the individual breakers at any time is limited to the rating of the panel's main breaker. This question mentions that the main breaker is rated at 200 amps. Any amperage over that will trip the main breaker thereby protecting the service supply conductors.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
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 a 200A 240V house panel be fed by number 2 conductors from a service entrance meter panel with 200A main breaker?
No, number 2 conductors are not sufficient to carry 200A. You would need larger gauge wires to safely handle that amount of current. It is important to match the wire size to the amperage rating of the panel to prevent overheating and potential hazards.
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.
How many KVA is needed for a 200A panel?
To determine the KVA needed for a 200A panel, you can use the formula KVA = (Voltage x Amperage)/1000. Assuming a standard voltage of 120V, the KVA would be 24 KVA (120V x 200A / 1000 = 24 KVA).

This wire size is able to handle the ampacity required for a 200A service safely and efficiently.

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
