Question Home lighting

Hi, I'm an amateur "do it yourself'er" and I have a question on wiring for lighting.
Project: I'm finishing the upper level of my garage and I need to run wiring for my light fixtures.
Objective: The following is the lighting design I desire.
1. Ceiling fan controlled with single dimmer switch
2. 5 recessed can lights controlled with single dimmer switch
3. 2 closet lights controled with single "normal" switch

Basically I would like to control these three "systems" seperately. Currently I have a single 30 amp curcuit 12/2 w grw romex running from my sub-panel to my 3-gang switch box. I would like to know how to wire this system? I would greatly appreciate any information or help. Let me know if I need to provide more info.

Well, first you need to do some more reading. A lot more reading.

You didn't say where you are from, but I am going to assume the US. If I am incorrect, please say so. Also, please update your profile so we know where you are from.

In the US you cannot use a 30 amp circuit for any regular lighting or general purpose circuits. 20 amp circuits are for specific loads, such as a room air conditioner, a compressor, etc. With 12 gage wire you can use a 20 amp breaker maximum.

You cannot control a ceiling fan with a dimmer switch. You need a speed control made by or at least approved by the fan manufacturer. Using a dimmer switch will either immediately ruin the fan motor, or hasten it's death.

You didn't say much about the closet lights, but closets have very particular requirements for lights.

You didn't say what this will be, but if it is a bedroom then it needs AFCI protection. You also didn't mention regular receptacles, but this room most likely needs to comply with the 6 foot/12 foot rule for spacing of wall receptacles.

Please supply some more information on what this room will be for and we can supply further information.

As for reading, I suggest that you start with Wiring Simplified, available in the electrical aisle of most big box stores. I also suggest at least one or two other books on home wiring.

There are numerous codes you need to be aware of, and unless you read something to learn them then you will make mistakes and fail the inspection that you need to have at the end of this little project.
