You are not protecting the wire from the meter to the 100Amp panel in your diagram. Section 14 of the Electrical code states that each ungrounded conductor must be protected at the point it receives its supply. Commercially we would use a splitter at that point, and follow that with a fused disconnect and then the panel. That would be too complicated and costly in a house.
