Sorry bringing up an old thread but I’m still in the process of getting this done. We’ve been doing a lot of remodeling of three bathrooms.
I don’t have another panel in or around the house. The electric comes in from the ground here where I live to a meter supplied by the electrical company and out to my 150amp electrical panel which supplies electric to each of my rooms/areas.
It’s a small panel and should have been a lot larger for this house (2500sq ft). We don’t seem to have issues with breakers tripping or anything. We don’t have solar or an electric vehicle. Not sure I need to upgrade my service to 200amp (it would be nice) but we don’t seem to have any issues.
However I would like to at least have a larger capable panel so that if I do decide down the road to upgrade the service to 200amp service my electrical panel is at least ready to go from there.
