Question

Quizplus · Accepted Answer

The electrical contractor is the one responsible for designing and installing the electrical system in a residential building. They will determine the appropriate amp rating for general lighting circuits based on local electrical codes and the specific needs of the building. The homeowner or architect may request a specific amp rating, but ultimately it is the responsibility of the electrical contractor to ensure the system is safe and up to code. The plumber is not involved in the electrical system design or installation.
