Services / Electrical PE stamping
Electrical PE stamping for power, solar, and NEC permit drawings
Electrical permits stall when the single-line, the panel schedule, and the load calculation describe different services. AllInStamp reviews those drawings against the NEC, or the CEC in Canada, and seals them with an electrical engineer licensed in the project state or province. Solar interconnection sets have their own page if that is the whole job.
- Single-line diagrams and panel schedules
- Load calculations checked against the service
- Solar, EV charging, and service upgrades
- NEC or CEC, plus local amendments
Electrical drawings we review and stamp
The sheets building departments ask an electrical PE to seal are the single-line diagram, panel schedules, load calculations, site electrical plan, and details for services, feeders, and grounding. Lighting and power plans come with them on commercial jobs. One-line diagrams that do not match the panel schedule — a 400-amp service on one sheet and a 200-amp main on the other — are rejected before anyone discusses the design.
The code is the National Electrical Code edition the jurisdiction has adopted, with that city’s amendments. Canadian projects are reviewed to the Canadian Electrical Code. We do not seal a set to a code cycle the department is no longer using.
Services, distribution, and data centers
Service upgrades, new distribution, and tenant electrical build-outs are stamped as permit sets: utility point of connection, overcurrent protection, feeder sizes, and the panel schedules that add up to the service. Include the utility’s available fault current or their service requirements when you have them. A single-line with a blank AIC is a common first comment.
Larger power work — data halls, switchboards, and emergency or legally required standby systems — needs the same match between the drawings and the calculations, plus a clear statement of what the generator or UPS actually feeds. Upload the riser and the equipment cut sheets together.
Solar PV, EV charging, and fire alarm
Rooftop and ground-mount solar need an electrical PE on the interconnection drawings and, separately, a structural check of the roof or the racking foundation. If solar is the whole permit, use the solar PV PE stamp page so both trades are scoped at intake. A solar sheet buried inside a general electrical set still gets reviewed. It should not be a surprise at plan check.
EV charging drawings need the charger load added to the existing service calculation, not drawn as if the service were new. Fire alarm risers and device layouts are often sealed by the electrical engineer as well. Sprinkler and standpipe design is a different license path, covered under fire protection and plumbing.
Who sends electrical sets
Electrical contractors send permit drawings when the city will not accept a design-build sketch. Solar installers send interconnection packages. Engineers send overflow work in states where the office has no electrical license. Architects send the electrical sheets of a TI when their usual consultant is not licensed there.
Price is by sheet count. A service-upgrade single-line is a short review. A multi-panel commercial tenant or a data-room distribution set takes longer, and the quote says so before you pay.
FAQ
- Can a PE stamp electrical plans someone else drew?
- Yes. An electrical engineer licensed in the project state can review drawings prepared by a designer or contractor and seal them after taking responsible charge. Code issues are corrected before the seal.
- Do you stamp single-line diagrams and panel schedules?
- Yes. Single-lines, panel schedules, and the load calculation that supports them are stamped together so the service size matches on every sheet.
- Do solar permits need a separate electrical stamp?
- The interconnection drawings need an electrical PE. The racking attachment often needs a structural PE as well. Solar-only jobs are scoped on the solar PV page.
- Which electrical code do you review to?
- The NEC edition adopted by the project jurisdiction, including local amendments. Canadian projects are reviewed to the Canadian Electrical Code.
