You will find we really have no national standard. This is regulated by state and local governments. If I was going to start, I would get the National Electric Code Handbook. That is the code with footnotes explaining what they are talking about. Guys like Mike Holt have web sites with useful information too. You could also get a "homeowner" book like the Time Life wiring guide, that gives a superficial explanation of how we do things. You should still be cross referencing that with the actual code though because they tend to skip over some important details. . You will find out pretty fast, not only do we drive on the wrong side of the road, we also do a lot of other things quite differently over on this side of the pond. We did start adding metric designations to the NEC so you will have a little common ground to work with.
I am sure folks here will be happy to help you out with questions. We have been looking for something to talk about
