Ive never understood why there has allways been such a big thing about the tandem (piggy back) breakers, the maker of the boxes say nothing about slapping in 100a breakers and mounting sub panels and loading with breakers, how could a few extra tandems every add up to that ?
Yea I thought thats why boxes have a main , to trip if overloaded , Just because a box has a lot of tandems in no way means that every breaker is loaded to max There could be a lot of circuits not often used or with light loads, but first thing a lot of electricians do when seeing a box with tandems is start telling H O how bad the box is already overloaded .
