Service entrance and main breaker layout — demonstrates how the main breaker panel distributes power and ensures grounding.
This depicts a service entrance and breaker layout. Power comes from the main service panel, passes through a 100A breaker panel, and supplies a load (like a water heater). Each section is properly grounded with rods, showing protection against faults.
This schematic focuses on grounding and bonding. It shows an outlet connected to an appliance, with the green wire bonded to a ground rod. The drawing emphasizes safe dissipation of fault current into the earth, preventing shock hazards.
