Any electricians in the house? :) I'm interested in upgrading my media room's juice. Currently, I have 2 dedicated 20 amp circuits that I added to my existing electrical panel many years ago, but I'm interested in adding more channels for Atmos and also a second subwoofer and also a beefy gaming PC for VR so I'm thinking I need more juice. My house was bought new back in 2005 so the wiring is reasonably up to date. How complicated/ expensive is it to have an electrician add a small dedicated sub panel specifically for the system vs. adding to existing panel. Currently, the house has 2 panels- one is outside the garage on the exterior wall and a sub panel is inside the garage coincidentally sharing a wall with my home theater. This is the panel that we added (2) 20 amp breakers to (my dad who is an electrician did the work). There are more empty breaker slots but I'm not sure if adding more is a good idea (I guess another question is how can I determine the max safe capacity of that panel?) Thanks for any help from the experts!
