I have been taught by many different Colleges, Trainers and Courses how to terminate a mains plug. The only one way that I believe is the correct way is the way that I was taught as a Post Office Engineer now alas BT.
1. Do not tin the wires for ac current connections, they will work loose, do not ask me how, something to do with frequency and change of current flow. My own decades of checking connections is that when tinned they do become looses over time.
2. You should always use wire strippers and not side cutters for obvious reasons.
3. The wires should be cut to length leaving the earth wire long enough so that if any wires are pulled out the earth wire is the last to be removed.
4. Ensure cord grip is firmly tightened.
