About eepdh

Education built on
depth, not shortcuts

eepdh was created for licensed electrical engineers who take their professional development seriously. Our courses go beyond surface-level code summaries — we provide rigorous, application-focused instruction grounded in the latest National Electrical Code cycle, helping you stay compliant, stay sharp, and earn the PDH credits your license demands.

Course Catalog
2023 NEC — First Release

Three courses.
One code cycle.

Our inaugural series focuses on three of the most actively evolving articles in the 2023 NEC — all directly relevant to modern energy systems, distributed generation, and interconnected power sources. Each course is engineered to deliver real comprehension, not just compliance checkboxes.

706
Energy Storage Systems
2023 NEC Article 706
Coming Soon
Article 706 governs the installation of energy storage systems (ESS) — from residential battery banks to utility-scale installations. The 2023 cycle brings significant updates to disconnecting means, arc energy reduction, and system classifications. This course gives you a thorough, practical understanding of ESS requirements so you can design, review, and approve compliant systems with confidence.
Key Topics
ESS classifications and equipment ratings
Disconnecting means and overcurrent protection
Battery management systems and ventilation requirements
Arc energy reduction requirements (2023 updates)
Interactive and stand-alone system configurations
705
Interconnected Electric Power Production Sources
2023 NEC Article 705
Coming Soon
Article 705 addresses the installation of systems that operate in parallel with a primary power source — including solar, wind, fuel cells, and micro-turbines connected to the utility grid. The 2023 edition refines interconnection requirements, load calculations, and supply-side vs. load-side connection rules. This course equips engineers to navigate the complex interplay between generation sources and distribution infrastructure.
Key Topics
Interconnection fundamentals and utility interface requirements
Supply-side vs. load-side connection rules
Feeder and service conductor sizing for parallel sources
Overcurrent protection coordination
Anti-islanding and transfer switch requirements
690
Solar Photovoltaic Systems
2023 NEC Article 690
Coming Soon
Article 690 is one of the most frequently revised articles in the NEC, reflecting the explosive growth of solar PV across residential, commercial, and utility sectors. The 2023 edition introduces updates to rapid shutdown requirements, wiring methods, and system labeling. This course provides engineers with a complete, current picture of PV system design and code compliance — from source circuits to inverter output.
Key Topics
PV system components and circuit definitions
Rapid shutdown requirements and 2023 revisions
DC and AC disconnecting means
String inverter vs. microinverter wiring configurations
Grounding, bonding, and system labeling requirements
Why eepdh
01

Code-Accurate Content

Every course is written directly from the 2023 NEC text. No paraphrasing, no outdated interpretations. You'll engage with actual code language, understand legislative intent, and learn how to apply requirements in real engineering practice — the way a licensed engineer should.

02

Built for Practitioners

These are not introductory overviews. eepdh courses assume a working knowledge of electrical systems and are structured to challenge and elevate practicing professionals. The depth here is deliberate — because your clients, your projects, and your license demand it.

03

PDH Credits That Matter

Fulfill your professional development hours without sacrificing substance. Our courses are crafted to satisfy state continuing education requirements while delivering learning that translates directly to your next design, plan review, or code inspection — not just a certificate on the wall.

The future of
electrical
continuing education

eepdh is in active development. Our first three courses — NEC Articles 706, 705, and 690 — are on the way. If you're an electrical engineer interested in early access, have questions about our curriculum, or want to explore partnership opportunities, we'd love to hear from you.
