Question
Chapter 7, Problem 1RQ
To determine
The definition of service entrance.
Expert Solution & Answer
Explanation of Solution
The service entrance is one of the most crucial components of a residential electrical system. The service entrance gives the home's electrical system access to the electric utility company's power supply.
The service conductors at an underground service entrance run from the service main disconnect terminals to the point where the underground utility wire is connected.
Several of the requirements for the installation of service entrances are covered by Article 230 of the NEC®. The specifications for grounding a residential service entrance are covered by Article 250 of the NEC®.
The local electric utility must be approached after the kind of service entrance being placed is selected, and the service type, location, and installation must all be planned with them.
Conclusion:
The service entrance gives the home's electrical system access to the electric utility company's power supply.

OK i need help. Please help me work thorought this with autocad. I am not sure where to begin but i need to draw this. Well if you read the question we did it in class and I got suepr confsued.
A square column foundation has to carry a gross allowable load of 2005 kN (FS = 3). Given: D₤ = 1.7 m, y = 15.9 kN/m³, 0' = 34°, and c' = 0. Use Terzaghi's equation to determine the size of the foundation (B). Assume general shear failure. For o' = 34°, N₁
36.5 and Ny = 38.04.

Flow is discharged from the pump into a 5 cm line, through a fully open globe valve and a standard smooth threaded 90° elbow before reaching a long, straight discharge line. The discharge line is 5 cm commercial steel pipe, 200 m long. Flow then passes a second standard smooth threaded 90° elbow before discharging through a sharp-edged exit to reservoir 2 (right). Pipe lengths between the pump and valve, and connecting the second elbow to the exit are negligibly short compared to the suction and discharge lines.
