How should I wire a new home for Automatic Lighting?
I believe there are two main differences for wiring a home for Automated lighting,:
1, Conventional wiring with local switches operating room lights.
2, Wiring a home with Automated lighting in mind.
Depending on your choice, these two different methods would be wired in different ways and it is important to grasp the basic concept!
Method 1,Conventional for many years usually incorporates a lighting ring main (cables from your Fuse box/ Consumer unit) for each floor or circuit, this means cable with power supply going directly to the lights and to local wall switches.
This means in practice all cables need to be able to carry high (240v) voltage and current between Consumer units/lights and switches (Bathrooms and wet areas being the exception).
Method 2, Differs from above in that Switches are wired to a central computer control point with smaller voltage handling size cable (or on a network). Heavy duty power cables are still used, however combinations of routes directly from the central computer controlled point and local fuse boards gives the ability to programme lights in many different ways and gives the ability for any switch to be programmed for any light or group of lights anywhere in your Home.
This means in practice NOT all cables need to carry high (240v) voltage and current between lights and switches.
