EV charging circuits wrapper
Why you care (60 seconds)
EV chargers are continuous loads with dedicated circuit and disconnect rules. If you miss those, you get red tags or unsafe installs.
Where people lose time
- Treating EVSE like a standard receptacle load.
- Missing required disconnecting means or labeling.
- Ignoring equipment instructions that set breaker size or wiring method.
This is
The rule in plain language
EV charging equipment needs a correctly sized circuit, proper protection, and disconnecting means as required by the equipment and the code.
When it applies
Any fixed or cord-and-plug EVSE connected to a branch circuit.
What you must do (checklist)
- Size the circuit for continuous load duty.
- Follow the EVSE nameplate and installation instructions.
- Provide required disconnecting means if not integral.
- Provide required GFCI protection when applicable.
Quick examples
- A wall EVSE that specifies a 60A breaker must be on a 60A rated circuit.
- A garage-mounted EVSE may require GFCI protection depending on location.
This is not
Common misreads
- Using a general-purpose circuit because the load is "temporary."
- Assuming a receptacle automatically satisfies EVSE requirements.
What it doesn't cover
- Service load calculations for large EVSE fleets.
- Utility interconnection or demand response programs.
False friends
- A welder receptacle is not automatically acceptable for EVSE.
Exceptions & edge cases
- Some EVSE include a built-in disconnecting means.
- AHJs may require additional signage for EVSE circuits.

Exam traps
- Forgetting EVSE counts as continuous load.
- Missing disconnect or location-specific GFCI.
Field notes
- Verify breaker size and conductor size against EVSE nameplate.
- Label the EVSE circuit at the panel and at the equipment.
