Everything You Need to Know about Low Voltage Wiring
Low voltage is electrical wiring and trim that does not carry the same current as the power outlets, fixtures, and switches. Items that are considered low voltage fall under less examination during inspections because the open wire does not pose the same electrocution risk that a standard wire would.
When Should Low Voltage be Installed?
Most of the low voltage installation will happen at the same time as the basic electrical. Other times, it will follow just after basic electrical. It can be done by a different crew of the same electrical company or a separate outfit that specializes in low voltage work.
What Items are Considered “Low Volt”?
Telephone wire and outlets are low voltage. Surround sound wiring and speakers, Television cable, and security pre-wires are as well.
The number and location of telephone outlets are not as critical today as it once was. Many of us use plug-in cordless phones. It is still wise to install wall outlets in any areas where you might want a computer terminal, in your bathroom, in the kitchen and where you have cable outlets.
With technological changes, have come more uses for cables. Consider whether you will be using Satellite TV or internet services. If so, be sure that the cable pre-wire contains the placement of a box where the Dish should be set. Because cable and satellite companies offer high speed internet services, it is a good idea to set cable outlets where you may be placing your computer.
A security system is almost automatic for many buildings or homes. Low volt wiring is run to sensors at window and doors and sometimes to motion sensors on the exterior of the home. Once the pre-wire is complete, any trustworthy alarm company can come in and present systems and programs to implement.
An intercom can be a great convenience. Most intercoms today also have a music player and radio as well. It is easy to use, and each zone of can be controlled by the individual.
