Advice Needed: How many amps required?
I know little to nothing about electrical matters, and need some advice.
We are doing a complete gut remodel of the 1960 3 Bed/2 Bath 1400 SF home we bought a year ago. House has gas Clothes Dryer, Water Heater and Furnace. Everything else is electric. House has (or will have) central air.
We are replacing a 100amp Zinsco obsolete electrical panel. I received several bids for the whole house project and it was discussed that upgrading service to 150 or 200 amps would be best. I hadn't yet agreed details with the selected GC.
I showed up to the job site last night to see they have already upgraded the panel and installed a 125amp Eaton panel.
I spoke with Electrician this morning and told him--hey, later I want to add exterior lighting, I want to add a spa, I don't just want what will get be my today--I've gotta plan for down the road. This s/b 200amps.
He disagreed with me saying it's overkill and we have tons of circuit bays and plenty of capacity for whatever we want to do in the future. I can't really argue with the guy because I don't know anything. All I know is everyone else told me 150-200 amps.
He also told me "it's not just 125 amps, you have 100 amps on both legs." I have no idea what that means.
Can anyone help me out here? Is this right? Should I insist on 200 amps?
