Not sure if this has been mentioned here yet but it probably wouldn’t hurt mentioning if it has been already.
Quoted myself from another post here:
Make sure you bond (using wire) any non current carrying metal to the ground wire from your plug. That means anything metal that isn’t supposed to have electricity on it i.e. Your frame ect. Trust me 
I’m a doctor… wait for it …of electricity. 
But Seriously. I am an electrician. That way if any wire gets frayed or damaged and touches any metal it will trip your breaker in stead of electrifying said metal until you touch it
