The main panel is 200 amp and there are 4 open spaces . I would like to know if adding a 100 amp subpanel would be taxing the limits of the main panel.
The panel is 200 Amp service- only 4 empty breaker slots - big ones are two central AC units, with 30amp breakers and an electric Oven with a 40amp breaker.
My plan was to add a 100amp breaker to feed the subpanel (with a main breaker, ) , I was planning to use #4 wire to feed the subpanel.
My biggest concern is that I may be adding too much by adding 100 amp subpanel , it is likely that the basement will get a fair amount of use .
This is what will be in the basement:
I am adding about 1200 sqft of finished space in my basement. My current panel is a bit full so i want to add a 100A Sub Panel, going to have around 22 recessed lights, ejector pump circuit, Dehumidifier Circuit, sink pump circuit, outlets
I understand , calling an electrician is best , I work as an electrician helper, I am trying to learn as projects arise.
