EETimes - The Myth of the Neutral Wire
Dec 08, 2004· The power wire that is grounded is called the "neutral" wire because it is not dangerous with respect to exposed metal parts or plumbing. The "hot" wire gets its name because it is dangerous. The grounding of the neutral wire is not related to the operation of electrical equipment but is required for reasons of safety.

Installation Practices: Keep Your PV System Well-Grounded
Apr 09, 2012· "If it's metal, it needs to be grounded," Colavito says. "That means the racking-and-mounting, junctions, frames — everything. If the steel bonding to your conduit is a metal pole, connect a copper conductor to it and conduct it to the ground. On PV systems, you always have to do equipment grounding — no one wants to be electrocuted."
