Regarding outlets used in RVs. All this theoretical posturing regarding square inches, nicked wires and everything else is kind of interesting. However, can anybody cite any real world instances of problems, fires or failed outlets as a result?
The issue, at least to me, is not necessarily which is better but more "are the outlets installed by manufacturers adequate".
Obviously, more contact is better than less contact. In much the same way that it would be more efficient and safer to wire 15A circuits with #4 wire as opposed to #12 or #14. However, testing and engineering have determined that #14 is sufficient so installing larger wire is unnecessary.
I'm just wondering if anybody can show that the outlets installed by manufacturers are inadequate for the task?
Of course business's are in the business to make money. However, I doubt they are in the business of burning down their products and injuring their customers.
