Question: I know you have addressed the practice of using 15 amp rated conductors for switch legs in residential 20 amp lighting circuits. I still have electricians saying it meets code. Will you try again? Thanks, Don Stephens Answer: Thanks for your comment Don.
I have often described the reliability of a fire alarm system installation as dependent on four elements: design, equipment, installation and maintenance. I have also explained that the last two elements contribute the most to a fire alarm system’s operational reliability.
