You have NOT been offered insults. You have been offered dispassionate
estimates of your ability. Your reaction itself led to my use of the

You simply do not understand that a description of a splice is almost
irrelevant; it is a very minor matter compared with *correctly *
diagnosing the problems in an installation that is undoubtedly faulty
and may have more than one major and dangerous violation of code.

You don't know what to do and you ignore the advice of experts. Does
that make you knowledgeable and wise?

No, it isn't rocket science, but it is still not as simple at the
practical level as you imagine.

Ah, well, you may doubt, but that only shows what you don't know. Find
out what a 'Y-capacitor' is and then think about the implications.

Again, that is elementary practical knowledge that you do not have. The
neutral is bonded to ground at the service entrance. But it must NOT be
connected to ground anywhere else.
