Question

Quizplus · Accepted Answer

The electrical contractor is responsible for making decisions about the type of electrical circuits that will be installed in a residential electrical system based on local building codes and the specific needs of the home. The homeowner and architect may provide input, but the contractor is ultimately responsible for the installation. The plumber does not typically have involvement in this decision.
