I am doing an old home re-wire, all new circuits. I am planning to add a 100A sub panel to give me more spaces to work with. I will feed the sub panel with a 50A breaker from the main panel.
If I fill all the spaces on the 100A sub, the draw would likely be enough to cause nascence trips on the 50A breaker.
How dose one go about calculating how many branch circuits can be added to a de-rated panel?
