Question:
Are there any standards for low-voltage wiring, such as structured wiring, security, central vacuum, audio, and video?
Answer:
The National Electric Code establishes standards regarding low-voltage wiring. They have a lot of information on their website at www.nfpa.org/. Also, Underwriter’s Laboratory has an article that refers to installation issues at www.ul.com/regulators/ode/0701.pdf.
