400 Amp Service-Really?
I’m pushing my GC to drill down on the estimates for our project and renovation. Trying to be brief, we’ll have a small, all electric house (2500sf) with 2 Heat pumps, condensing dryer, induction stove, microwave, ERV and Heat Pump hot water heater.
The detached 3 car garage with an upstairs apartment will have almost exactly the same, with the Heat Pumps most likely being smaller.
Their electrician of choice is telling us that we’re going to need to upgrade to 400 Amp service or run a second 200 Amp service. I find this hard to believe, but these guys usually know what they’re doing.
Running new utility wire from the street will be costly I’m sure, not to mention trenching or a new pole etc.
Does this sound right? I’ve never heard of 400 Amps for a home.
