Main Circuit Breaker Switch

My TT has 30 amp service now, just don't understand why they place all these appliances in it if main circuit breaker isn't going to allow them to work at same time. Is there any recourse from my point against the dealership that sold me the unit?

Golden HvAC said it best, and from my experience, he usually does.

Simply put (perhaps too simply) any electrical system is designed to allow many branch circuit amp ratings to total more than the main amp rating from a cost standpoint. You can run a bunch of things on many circuits that will not trip their individual branch circuit overload device, but will total more than the main can handle. There are a lot of misconceptions about how these systems are designed, but if you read the code book enough, you'll soon realize this is how it is. Check the panel in your stick house and you see I'm correct. The total of your specific and non-specific loads will exceed the rating of your main breaker, and that is allowed in code by percentage. Turn every thing in your house on at the same time and it will likely trip the main, but not any individual branch circuit breaker. I won't bore you with the nuts and bolts of why, but it's true in almost every case. It's set up that way for safety, as well as a best case (not every case, all case)day-to-day, cost-effective installation. You can up-grade these systems to handle all loads, all the time, every time, but most folks don't like the price point. There is a realist accepted standard that we tend to live with. The code book is a guide for minimum safe standards. You are free to pursue upgrades at the limitation of your purse strings as long as you adhere to those minimum standards. The importance of covering all loads, all the time, simply isn't that necessary for most people.
