2nd that Trumpy.
Our current system of house wiring (I’m not concerned with commercial and industrial) needs new/improved products and procedures, to make it safer and easier.

This may require mistake-proofing, similar to the 3.5 inch computer diskettes being insertable only one way.
A noble aspiration, although not easy to achieve.
