200A service here. At some point may need to upgrade to 400A. I don't think EV charging is a huge deal for many. 20-30A / 240 will usually charge you overnight

I don't think EV charging is a huge deal for many. 20-30A / 240 will usually charge you overnight. You can run it after you are done with the induction stove. I think 100A service can still work for quite a while. Heat pumps are maybe the most iffy thing.
- nemo44x 4y agoYou need to consider in old homes (of which there are millions and will continue to be) things like AC are run in multiple zones since the ducts were added decades after the homes was built it's just easier to have multiple units. Also as the home scales in size you need more units, including heat pumps if you go that route. So you have a couple of these units running at 30/40/50A each and a couple cars plugged in, possibly one of them needs super charging so it's using 50A and someone has 3 induction burners going and the electric dryer is running while your teenager blow dries their hair. Not to mention all the passive things likke the fridge/freezer, lights, charging devices, etc. Point being, at any given time there's a combination of things that could need power and you have to be able to support that.
- brianwawok 4y agoSee other thread. If your house is taking multiple 30 amp AC splits, something is wrong with your setup. Many mini-splits run on 120V 15-amp.. the same plug as a vacuum or microwave. Edit - Also make sure you understand the difference between 120 and 240V circuits. Not entirely clear you do.
