Default DIY Lighting Control Help/Ideas/Theory

Hey everyone,
I want to build a lightning control module for my home theater system.
I have a theory but not sure if this will work or not, but here it goes:

Take 10 - 12v Relays and mount them on a panel.
Take the 12volt trigger and attach that to the 85 side of the relays.
Take -12v (ground) and attach that to the 86 side of the relays.
Take the neutral AC wire and attach that to the 30 side of the relay then connect the other side of the neutral AC wire to the 87A side that goes out to the lights.

Theory is that when the +12volt trigger is received, then the relays will cut the neutral wire going to the lights.

Is this possbile?
Or am I outta my mind?

The National Electrical Code prohibits the switching of a neutral wire unless the corresponding hot wire is also switched by a device that switches them both at the same time. Switching a neutral is a safety hazard as well as a fire hazard. There are low voltage relay systems available that can work, I would suspect, for what you want to do. They are fairly common for residentioal use.

Best practice is to switch both live and neutral, but leave ground connected. However, I believe that X10 type control stuff is easily available and relatively cheap, so if you are not sure of the safety aspects, then that would seem to be the way to go.

Just swap for the live wire, thats the only safe way, plus figure
your load to main feeder, and put a beaker inline. and you should be good to go.
