You don't understand. Even if you are a competent blue collar person and you build your own house today, you hire qualified electricians. Everyone does this. It's a rule written in blood.

It might just kill you now, or get red hot later under certain conditions you haven't tested. If you can't see that this gongshow is obviously dangerous then you are a fool.
