Integrated electrical and low-voltage systems of all types—inside and outside a building—encompass the range of work that electrical contractors do.

Do you have a customer that requires additional access control at specific locations within their facility but no budget for a total rip and replace? Maybe they are concerned with hacking or data compromise.

The categories or labels used to describe the plethora of power quality phenomena that can occur on electrical systems have not changed much in the past decade or two. Measurement methods and acceptable limits for most systems have changed.
