Building a new home, charging advice

[Redline]

We signed the final contract to build today. We start the teardown next week.

I did see the spec for the electrical and its a 400amp panel for the house and two 60A circuits to the garage.

I don’t know all the specifics, but we’ll be walking the entire house with the electrician once the house construction has started.

It should be far cheaper to run a single sub-panel (120A+/-) with aluminum service wire instead of two runs of copper. That also give you the flexibility to run different types of loads instead of just 2 EV chargers since you have a full panel in the garage.

As a method of somewhat future proofing, I’d request oversized conduit be run from the breaker panel to charger locations. that way if more powerful chargers or an extra wire is someday needed, it can easily be pulled without any tear out.
