Systems

 

 

Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do. The articles in this section highlight different types of work, from security, fire and life safety, to traditional electrical power and distribution, to lighting, cabling and more.

McClure Electric, San Francisco, has been in business since 1966, but it wasn’t until the mid-1990s that it got involved in low-voltage work.
