A centre punch is just like a hard, thick nail. If you put it against metal and hit it with a hammer you get a little dot, a small pit with a raised edge. It's useful if you're drilling a hole and want to control where it goes. You put the punch where the centre of the hole is supposed to be and then the raised ridges will help center the drill.

Can you use a main lug panel for your home or do you have to use a panel with a main breaker?
The service distribution needs to have a disconnect from the utility supply. Most homes use a combination distribution panel. If the home owner wants to have a load center installed then there has to be a fused disconnect ahead of the panel. The less costly of the two options is the combination panel. Labour costs drive the load center, main service switch option much higher because there are more materials to assemble.
