Can I install a 150 amp sub panel to a 200 amp panel with the sub running (3) 50 amp
Asked Jan 3, 2012, 12:59 AM
I have square D QO panel. I am adding a Stiebel 29 on demand water heater and it calls for (3) 50 amp 240V breakers. Can I add a subpanel that has (3) 50 amp breakers to tie into my existing 200 amp service? If so what gauge copper wire would connect the two and does Square D QO make a 150 amp breaker that will fit within the 200 amp box? Please give me your thoughts. Thanks so much!
