A "lighting panel" is simply a panel in a house.... or in some cases a business which handles among other things, the lighting loads.
In a house the lights and the general purpose outlets are considered to be part of the lighting load as calculated in the square foot method. We often use the wall outlets to plug light fixtures and lamps in. In most houses, this also includes the heavy loads like range, dryer, and HVAC.
However, by using the power panel as I described, you are able to unload all of the heavy loads to the service equipment. This clears up spaces in the "lighting panel" and lowers the load on it. Good all the way around.
http://www.bing.com/image...&selectedIndex=169 I tried to find a picture of a power panel. ^^^^ this is as close as I could find with a quick search.
The power panel I talk about is simply a single can/box with a built in meter base, and a main 200a built in CB with room for 6 double pole breakers. Even though it may look like there is room for more than 6 DPCB in the right side, the buss bar configuration of a panel like this only allows room for 6DPCB to be installed. (code requirement)
A bit more on that white wire hot issue..... back a number of years, it was legal to use a romex cable with 2 wires and a bare ground to feed a 240v load. The ground would serve as ground and neutral in many cases. As accidents happened as a result, the codes were re-written to improve safety and now a 4 wire circuit is required with red & black as hot, white is neutral and bare equipment ground. Old circuits, as long as they are properly fused for wire size are grandfathered and need not be removed BUT, the white does need to have "permanent" color coding to eliminate the danger associated with people thinking white wires are "safe". Color coding is to be on both ends and in ALL junctions on that circuit.
This is the reason they still sell 3 wire dryer & range pigtails and outlets. All new installs require 4 wire circuits on dryers and ranges.
Doing your own work: If you own the house AND live in it as your primary residence full time...... in NC you are allowed to perform your own repairs. You are still required to obtain the proper permits and the job will be inspected by an inspector. All applicable codes must be followed to the letter and failure to do so will be cause for a failed inspection. They probably look closer at a homeowner's repairs than they would at a licensed electrician's work whom they know to do excellent and conscientious work.
If there is something you do not understand, let me know and I'll try to splain it better.
