EV feeder records before rough-in closeout
A useful EV rough-in packet ties the charger model, approved load, breaker/output setting, route, conductors, raceway, labels, inspections, photos, and commissioning handoff together before the work is covered.
Direct answer
Before an EV charger feeder or branch-circuit rough-in is closed, record the charger model, manufacturer instructions, approved load or output setting, circuit rating, source panel, breaker or overcurrent device, conductors, raceway or cable type, route length, voltage-drop basis, disconnect or GFCI basis, equipment listing/certification record, labels, inspection status, photos, commissioning handoff, and open exceptions.
A photo of a cable in a wall is not enough. EV charger installations often depend on the exact charger model, output setting, breaker size, load management, service capacity, manufacturer instructions, permit scope, and final commissioning. If those assumptions are not recorded before cover, the trim or commissioning crew inherits a guessing problem.
Use this as documentation guidance only. The adopted code edition, AHJ, permit drawings, utility or service rules, engineered design, equipment listing and markings, manufacturer instructions, qualified electrician, owner standards, and site safety plan control the actual installation.
Start with charger identity and approved load
The rough-in packet should start with the charger or EVSE identity. Record manufacturer, model, catalog number, connector type if relevant, hardwired or receptacle plan, installation manual version, nameplate rating, requested output, and any software or commissioning setting that limits output.
This matters because two chargers that look similar can have different terminal ratings, breaker/output settings, GFCI instructions, mounting clearances, power-sharing options, labels, and commissioning steps. A rough-in that is correct for one unit may be wrong for another.
If the installed charger is not known yet, write that as an exception. Record the provisional load assumption, spare raceway or pull-box strategy, owner decision needed, and what cannot be closed until the exact equipment is selected.
Record the source, circuit, and load basis
The packet should identify the panel or source, circuit number if assigned, permit or plan reference, load calculation reference, demand or load-management assumption, breaker or OCPD basis, conductor basis, and whether the installation is feeder-fed equipment, branch-circuit EVSE, or a multi-charger group.
Do not let a field note become the load calculation. The field note should show where the load value came from and which document controls it. Approved drawings, engineer comments, panel schedules, service studies, utility coordination, owner standards, and manufacturer settings may all affect what can be installed.
If load management or power sharing is part of the installation, preserve the basis before cover. Record which chargers are in the group, which feeder or panel serves them, what communication or control wiring is roughed in, and who will verify the final configured limit.
Route evidence matters before the wall closes
A useful rough-in packet shows the route. Record wall, ceiling, slab, trench, sleeve, deck, pull point, panel, junction box, disconnect, charger location, raceway/cable path, bend or pull access, firestop location, outdoor transition, and any place the route changes from the approved plan.
For long EV feeder routes, record measured length and the voltage-drop basis used by the design or estimator. Do not state that voltage drop is accepted just because a larger conductor was pulled. Write the route length, conductor, load assumption, calculation reference, and who accepted the result.
Photos should show more than copper. Capture panel/source, raceway or cable markings where visible, conductor tags, pull boxes, sleeves, trench depth marker if applicable, wall cavity route, firestop before cover, disconnect or junction location, charger rough-in height, and labels.
Manufacturer instructions and labels are not paperwork extras
EVSE manufacturers may require specific installation steps, breaker or circuit settings, output-current configuration, commissioning app steps, power-management setup, labels, and owner handoff. The rough-in packet should identify which manual was used and which final settings remain for trim or commissioning.
If the equipment uses an app, QR code, commissioning credentials, or configured breaker size/output setting, record who owns that final step. A rough-in can pass inspection and still fail the owner if the charger is later configured above the documented circuit basis or left unregistered.
Labels belong in the record. Capture panel schedule updates, circuit directory, charger label, breaker/output setting label where provided by the manufacturer, disconnect label where required by the project, and any load-management group label.
Minimum EV rough-in packet
Use the approved electrical permit set, inspection card, commissioning checklist, or owner EVSE form first. Add a field packet where the required form does not preserve the rough-in assumptions clearly enough.
| Record item | Field detail | Why it matters |
|---|---|---|
| EVSE identity | Manufacturer, model, manual version, hardwired/receptacle plan, listing/certification record | Prevents rough-in assumptions from being applied to the wrong charger |
| Approved load | Output setting, circuit rating, load calculation, power-sharing/load-management basis | Ties feeder work to the actual charging assumption |
| Source | Panel, switchboard, transformer, circuit number, OCPD, spare capacity reference | Shows where the circuit originates |
| Conductors | Size, material, insulation, equipment grounding conductor, conductor tags, terminal basis | Keeps hidden wiring reviewable |
| Raceway/cable route | Raceway/cable type, route length, pull points, sleeves, wall/ceiling/trench path, firestop | Preserves work that may be covered |
| Controls | CTs, load-management wiring, network/communication rough-in, control cabinet, gateway | Protects commissioning assumptions |
| Product requirements | Disconnect, GFCI, labels, mounting height, clearances, outdoor rating, manufacturer notes | Separates product-specific details from guesswork |
| Inspections | Permit, rough inspection, correction notices, AHJ comments, utility notes | Shows the approval path |
| Exceptions | Unknown charger, missing manual, changed route, load calc pending, label pending, commissioning pending | Prevents unresolved items from disappearing |
| Release | Released to cover, partial release, hold, recheck required, responsible approver | Protects the closeout decision |
Before rough-in closeout checklist
Run this check before walls, ceilings, trenches, slabs, or equipment spaces are closed.
- Confirm the EVSE model, manufacturer instructions, approved output setting, and circuit/load basis.
- Confirm the source panel, circuit number, breaker/OCPD, conductor, raceway/cable, and equipment grounding path are recorded.
- Photograph the route from source to charger location before it is covered.
- Record measured route length and voltage-drop calculation reference where the project requires it.
- Confirm sleeves, pull points, junction boxes, disconnects, firestop, outdoor transitions, and equipment locations.
- Record load-management, CT, communication, or network rough-in where applicable.
- Capture panel schedule, circuit directory, charger label, breaker/output label, and disconnect label status.
- Keep permit inspection comments and correction notices in the packet.
- Record what remains for trim, startup, commissioning, app configuration, owner registration, and training.
- Hold closeout if charger identity, load basis, inspection status, route evidence, or safety-critical product requirements are unresolved.
Failed or held items need a correction chain
If a rough-in area is held, keep the original hold in the packet. Write the location, reason, photo reference, responsible party, correction, and recheck result. Do not replace the failed observation with a clean final note.
This matters when a route changes, a conductor size changes, a breaker changes, a charger model changes, a panel schedule changes, or a commissioning setting changes. The record should explain what changed and who accepted it.
If the correction affects load calculation, conductor sizing, raceway fill, voltage drop, GFCI/disconnect, listing instructions, utility coordination, or inspection scope, the field record should point to the updated controlling document instead of trying to approve the change by itself.
Weak and strong notes
Weak note: EV feeder roughed in, ready for drywall.
That note does not identify the charger, load, output setting, breaker, conductor, raceway route, panel, voltage-drop basis, inspection, labels, manufacturer instructions, or commissioning handoff.
Stronger note: EVSE rough-in for chargers EV-1 and EV-2 at parking level P1 checked before ceiling close. Approved plan E4.2 revision 6 and charger manual version saved in packet. Panel EDP-2 circuits 33 and 35 assigned. Conductors, raceway route, pull box PB-EV-1, sleeve through wall P1-C, and charger stub-up locations photographed before cover. Load-management CT conduit installed to controller cabinet; final load-management configuration remains commissioning item. Rough inspection passed with correction note closed. Panel schedule updated. Charger output setting label and owner app registration remain open trim/commissioning items.
The stronger note works because it separates rough-in release from final startup. It tells the trim crew exactly what still needs verification.
Questions that come up
Can rough-in close before the exact charger is selected? Only if the project, engineer, AHJ, owner, and qualified electrician accept the provisional basis. The packet should state what assumptions were used and what cannot be finished until the actual EVSE is selected.
Does the breaker size determine the charger output? Not by itself. Charger output depends on equipment rating, code rules, conductor/raceway installation, breaker or OCPD, manufacturer instructions, and any configured output or load-management setting. Record the controlling basis.
Do voltage-drop notes belong in the rough-in packet? Yes, where route length or conductor size affected the design or cost. Record the measured route, conductor, load assumption, calculation reference, and approver.
Who owns commissioning settings? Use the project responsibility matrix, manufacturer instructions, owner requirements, and qualified installer. The rough-in packet should name the responsible party and identify which settings remain open.
Compliance and safety limits
This field note is not an NEC ruling, electrical design, load calculation, utility approval, equipment listing decision, energized-work procedure, or manufacturer instruction. The adopted code edition, AHJ, utility, approved drawings, engineer, equipment markings, manufacturer instructions, qualified electrician, and site safety plan control the work.
Do not use this checklist to bypass permits, inspections, lockout, energized-work rules, PPE, GFCI/disconnect requirements, listing instructions, load calculations, utility coordination, trenching safety, firestopping, or site-specific safety procedures. The record preserves the rough-in decision chain. It does not authorize unsafe work or unapproved EV charging installation.
