No, if the UL Rated Listing for the Panel is 200A than that's it. You cannot have 300A flowing through a 200A Panel.

How many amps will 10-2 wire carry at 100 feet?

A #16 copper conductor is not a wiring size that is used in homes. This is because the smallest breaker for residential use is rated for 15 amps. A #16 copper conductor is only rated at 13 amps. For a load of 13 amps over 100 feet a #12 copper would be required.


Is it safe to have 200 plus amps in breakers inside than 90 amps on the main service breaker outside?

I am assuming by your description that the panel is protected by a 90 amp breaker and the breakers in the panel when added up is 200. This is okay as long as your 90 amp breaker trips on a regular basis. It is typical for the breakers to add up to more than the main breaker under the assumption that you would rarely be running each circuit at its maximum capacity.


How can you tell what the amp service is in your house?

I would have to say that the amperage label on the main breaker would designate the amount of amps coming into the house.Look at the number on the handle of the main breaker. That number is the rating of the breaker and at what amperage the breaker will trip. If you have a main fuse switch the number on the fuse is the tripping amperage. This will be the amount of current that the service is rated at.


What size breaker is needed for a 240 volt 34 amp hot tub?

Add 25% so it comes to 42 amps


What size breaker would i use to add a 100amp subpanel?

Any size two pole breaker up to the value of 100 amps. Just make sure that the wire used to connect to the sub panel from the main panel is of a size to correspond to the breaker size. Wire amperages at 90 degrees C are, 30 amp #10, 40 amp #8, 55 amp #6, 95 amps #4,110 amps #3. Also keep in mind to look and see if the sub panel is rated at 100% or 80% load capacity. If it is only 80% load capacity then reduce the amperage rating of the conductors by 80% to obtain their new capacity rating.
