What's the diff between main lugs and Mechanical lugs

Can you please explain main lugs versus mechanical lugs? Here's my situation. I need a meter base and main disconnect on the outside of the house. I then wanted to put a 200 amp load center on the inside (other side of wall). What type of boxes/panels/lugs do I use. Can I put a 200 amp meter/main panel on the outside and then how do I get the cables to the load center? Is there something I can bolt onto the bus bars inside the panel? I'm hoping that is what lugs are? Where do they go? What size cable would I use to go 3 or 4 feet for 200 amps? Thanks

Main lugs generally means no main circuit breaker, just a place for the wires to terminate on lugs.
Mechanical lugs are a type of wire termination that allows you to slide the conductor in the termination, then you tighten a threaded screw to hold the conductor and help make good contact for the whole termination. There are several, but the two main methods to terminate a conductor is mechnical and compression.
