Power-line communication (PLC) is a communication method that uses electrical wiring to simultaneously carry both data and electric power.
It is also known as power-line carrier, power-line digital subscriber line (PDSL), mains communication, power-line telecommunications, or power-line networking (PLN).
A number of difficult technical problems exist between wireless and power-line communication, notably those of spread spectrum radio signals operating in a crowded environment.
The wiring providing power to the refrigerator, also serves the lighting, and probably other receptacles in the kitchen.
The wire is too small to provide sufficient current to all the outlets, thus causing the lights to dim. In other words, the electrician will install a second wire from the panel to supply current to some of the outlets presently served by only one wire.
A wide range of power-line communication technologies are needed for different applications, ranging from home automation to Internet access which is often called broadband over power lines (BPL).
Most PLC technologies limit themselves to one type of wire (such as premises wiring within a single building), but some can cross between two levels (for example, both the distribution network and premises wiring).
Note: It's ONLY at the MAIN panel where the ground and neutral (white) wires are connected to the same bus bar.
At the sub-panel, the neutral bus needs to be isolated (insulated) from the metal panel box.
Visibly dimming lights shouldn’t be happening whether you have a new service or not, but is probably not related to the service.
People often mistakenly believe that a house with a new electrical service has new wiring throughout the house. The service normally only includes the cable that mounts on the outside of the house, the meter box and the distribution panel, or breaker box.
This cable needs to enter the main panel at arrow 1, so we had to re-route the cable behind all those other cables.
We connected the ground and the neutral wires to empty slots in the bus bar.
Replacing all the wiring in a house is a much more expensive proposition than replacing the service.
