What are the GFCI requirements for an EV charger in Utah?
A receptacle installed for EV charging, such as a NEMA 14-50, needs GFCI protection under NEC 625.54, which Utah did not amend. That usually means a two-pole GFCI breaker. A hardwired charger is not covered by 625.54, and listed Level 2 chargers have ground-fault protection built in, so most makers call for a standard breaker.
Utah has used the 2023 NEC statewide since July 1, 2025. Mike Holt Enterprises summarizes 625.54 this way: "Receptacles for the connection of electric vehicle supply equipment must be GFCI protected." Its author's comment adds that the requirement "only applies to cord-and-plug-connected EVSE."
How did Utah change the GFCI rule?
Utah amended NEC 210.8, the general GFCI section, in two ways that matter here. It deleted the words "through 250-volt" from 210.8(A), so most 240 volt receptacles in homes are no longer GFCI-required by that section. It also deleted 210.8(F) entirely. Neither change touches Article 625, so the EV receptacle rule stands.
| Rule | What it covers | Status in Utah |
|---|---|---|
| NEC 210.8(A) | GFCI for dwelling receptacles in listed locations | Amended: the words "through 250-volt" deleted |
| NEC 210.8(F) | GFCI for dwelling outdoor outlets | Deleted |
| NEC 625.54 | GFCI for receptacles installed for EV charging | Not amended: applies as written |
Amendments from Utah Code 15A-3-601, subsections (2) and (7), effective July 1, 2025. Read October 4, 2026.
The result surprises people. A 240 volt welder outlet in the same garage needs no GFCI under Utah's rule, while an identical 14-50 installed for a car does. What decides it is the purpose of the receptacle.
What protection is already inside the charger?
A charge circuit interrupting device, or CCID: ground-fault protection for personnel built into listed Level 2 chargers and tested under UL 2231. ChargePoint's datasheet lists a 20 mA CCID with auto retry, Wallbox lists 20 mA per UL 2231, and Tesla's Gen 3 Wall Connector manual lists it as "Integrated, no additional required (CCID20)."
That built-in protection is why makers object to a second device upstream. ChargePoint's datasheet puts it plainly: "External GFCI may conflict with internal GFCI (CCID)." The two also behave differently when they trip. ChargePoint lists its CCID with auto retry, so the charger can try again on its own. A tripped GFCI breaker stays off until someone resets it at the panel; Emporia notes that redundant protection "requires a manual breaker reset."
For plug-in owners who face a GFCI breaker requirement, Emporia's advice is to buy the hardwired version of its charger instead, and ChargePoint recommends a hardwire installation in the same situation.
Which breaker goes with which setup?
For a receptacle installed for EV charging, a two-pole GFCI breaker matched to the receptacle, 50 amps for a 14-50. For a hardwired charger, follow the manual: most call for a standard two-pole breaker. The breaker size still follows the 125 percent rule either way.
| Setup | GFCI breaker | What the maker says |
|---|---|---|
| NEMA 14-50 or 6-50 for a plug-in charger | Required by 625.54 | ChargePoint and Emporia warn of nuisance trips and suggest hardwiring where code requires GFCI |
| Hardwired ChargePoint Home Flex | Not required | "For hardwired installations, use a non-GFCI circuit breaker" |
| Hardwired Emporia | Not required | "Always use a standard non-GFCI breaker" |
| Hardwired Tesla Wall Connector | Not required | 2020 Gen 3 manual: "do not install a GFCI circuit breaker" |
| Hardwired Wallbox Pulsar Plus | Not required | Added GFCI breaker "optional, as per article 625.54" |
Tesla's Wall Connector guidance does not carry over to Tesla's Mobile Connector, which plugs into a receptacle; we found no Tesla statement on GFCI breakers for the Mobile Connector.
A NEMA 6-50, which has no neutral, is treated the same way as a 14-50: 625.54 applies to any receptacle installed for EV charging, whatever its configuration. Breaker sizing is in what size breaker for an EV charger.
Why do GFCI breakers trip with plug-in chargers?
Two layers of ground-fault protection can interact. ChargePoint says a GFCI breaker, "especially with a plug-in installation, can cause nuisance breaker tripping," and Emporia says redundant protection "will cause nuisance tripping." Removing the GFCI from an EV receptacle is not a legal fix. Hardwiring the charger is.

What about outdoor outlets?
An outdoor receptacle installed for EV charging is still a receptacle under 625.54, so it needs GFCI protection plus a cover that stays weatherproof with the plug in. ChargePoint's datasheet says an outdoor plug-in install needs "an outdoor rated GFCI breaker upstream," and it recommends hardwiring outdoors.
The NEC wet-location rule for 30 amp and larger receptacles serving unattended loads calls for an enclosure that is weatherproof "with the attachment plug cap inserted or removed." Utah's deletion of 210.8(F) removes the general outdoor-outlet GFCI rule for dwellings, but it does not change 625.54 for EV receptacles. Planning an outdoor unit is covered on our outdoor EV charger installation page.
Does this affect bidirectional charging?
Yes. Mike Holt's commentary on 625.54 notes that GFCI breakers or receptacles typically used in homes "are not suitable for back feeding," which rules them out for a bidirectional charger. Because 625.54 applies only to cord-and-plug equipment, hardwired equipment is the route for vehicle-to-home setups.
Your inspector has the final say on how these rules apply at your address. In Ogden, South Ogden, North Ogden and Ogden Valley City, a new charging circuit or receptacle needs an electrical permit and inspection; see EV charger permits.
EV charger GFCI questions
Does a NEMA 14-50 for an EV need a GFCI breaker in Utah?
Yes. NEC 625.54 requires GFCI protection on receptacles installed for EV charging, and Utah did not amend that section. Utah's change to the general GFCI rule, NEC 210.8, does not reach an outlet installed for a car. In practice that means a 50 amp two-pole GFCI breaker.
Does a hardwired EV charger need a GFCI breaker?
Not under 625.54, which covers receptacles. A listed Level 2 charger has its own ground-fault protection built in, and ChargePoint, Emporia and Tesla tell installers to use a standard breaker on hardwired units. Wallbox calls an added GFCI breaker optional. Follow the charger's manual and your inspector.
Can I swap the GFCI breaker for a regular one to stop nuisance trips?
Not on a receptacle installed for EV charging. That would remove protection the code requires. The fix ChargePoint and Emporia point to is hardwiring the charger on a standard breaker, which takes the receptacle, and the 625.54 requirement, out of the picture.
Does a regular 240 volt garage outlet need GFCI in Utah?
Under Utah's amended rule, generally not: the state deleted the words "through 250-volt" from NEC 210.8(A). The exception is a receptacle installed for EV charging, which falls under 625.54 instead. If the outlet's purpose is charging a car, plan for GFCI protection.
