Does anyone know a site that can help me or maybe even a book . It would be appreciated greatly. Im whanting to expand my buisness by learning more about this topic. Thanks
P&S also offers some training on low voltage systems. My state requires a seperate license for any work under 90v, which I have. As for books, BICSI is the low voltage equivelent of the NEC. It is the main source of codes and requirements for telcos and voice/data installations. My company does a great deal of voice, data, video and audio installs. It brings about twice the profit of the standard electrical outlet.
