I am spec'ing out my electric, and for now I am not going with automation - I was looking at an intermatic 100 amp integrated panel with timer (i need a timer for the SWCG). Is this the way to go, or would it be better to use a standard sub panel and then install a stand alone intermatic timer off box to control the SWCG? One thing I am seeing on the intermatic sub panel is the knock outs appear to be too small for the size conduit I need. Anyone with sub panel and timers want to weigh in?
