EVSE Load

[Xformer680]

Hello,
Is the EVSE Load required for new dwelling units or does it depend on the code section adopted by the AHJ?

 

[jaggedben]

Has the NEC ever required installation of an EVSE or EVSE circuit?
NO

Has the NEC always required inclusion in load calculations of an EVSE that is/will be installed?
YES

Has the NEC ever required inclusion in load calculations of an EVSE that isn't/won't be installed?
NO

Do some states and local jurisdictions enforce energy codes or other ordinances requiring installation of an EVSE circuit and/or inclusion of an EVSE in load calculations in new dwelling units?
YES

YES
Though that can take the form of empty conduit pipe (my preferred solution), and a dynamic energy load calculation (my preferred solution).

What is a dynamic energy load calculation?
Illinois requires 9600 VA @ 240 volts of capacity for a future EV charger in a dwelling. The do permit the use of an energy management system to limit the required service capacity, but I don't think that is what you are talking about.

I think he's in fact talking about an energy management system. Most common being one that's integrated to the EVSE and reduces its allowed draw if total load gets too high.
