All lesson material focuses on one thing: installing a safe, code-compliant electrical service in accordance with the 2023 NEC.
Instead of treating service installation as a single block of code, you’ll walk through it as a sequence of on-the-job decisions — where the service conductors originate, how they're sized and installed, what equipment protects the service, and how everything gets disconnected safely.
You will end the training by working through practical scenarios that put those decisions into a real installation context.
After completing the lessons, you will be able to:
- Explain how the NEC's structure applies to service installation work.
- Locate the relevant NEC sections governing service installations.
- Apply the code requirements for overhead service conductors.
- Choose and install service-entrance conductors that meet code.
- Rate service equipment according to NEC standards.
- Position and size service disconnecting means correctly.
- Provide proper overcurrent protection for a service installation.
- Work through real-world scenarios covering conductor location, equipment rating, conductor selection, disconnects, multiple services, panel identification, and ground-fault protection of equipment (GFPE).
