hI y'All,
Just a quick note on EMF's, there ain't no DC transformers. The
electromagnetic flux, or field is created by a change in current flow.
PV circuits are DC constant current, ie: no EMF.
An AC source, power line, radar, ham radio etc. can induce current into
a DC line, (triggers the GFCI breaker), twisted pairs might help balance
this stray induction.
Everything that can pass electrons, and is not a current carrying
conductor should be grounded. Neutral conductors must be ground bonded
at one point.
John Wiles just points at the NEC grounding book on his table (an inch
thick) and says "look it up"!
