Home Load Calc EV charger

[Sierrasparky]

Went to look at a EV charger install.
The Electrical required is a 40amp 240v circuit.
The unfortunate thing is the Town home only has a 60 amp service and is group metering.
The home has A/C (3 ton) and is about 1200 Sqft. all gas appliances. I calculate just under 60 amps load. So I told the lady a no go.
I get a call from her telling me that another Electrician says no problem we can do this with your 60amp. panel you have.

Question is do we ignore the calculations because we feel the actual load will never exceed the 60amp.

From my perspective, you would not be asking if you didn't already know the right thing to do. :happyyes:

There are chargers with enable/disable low voltage control connections.

Possibly the new electrician knows that one can interconnect the AC thermostat with the enable/disable to assure both are not on at the same time.


Or is that an assumption that the 'new guy' is smart enough?

Thanks any particular brand.

I'm only familiar with industrial versions such as:

I'm not up to date on all the electric vehicle chargers out there.
