In a grounded system, normally non–current-carrying electrically conductive materials that are likely to become energized, such
as building metal framing and metal water piping, shall be connected together and to the electrical supply source in a manner that establishes an effective ground-fault current path.a.trueb.false
Explanation:Grounding of electric currents are a major factor that helps to guarantee the protection of buildings against power surges and fire from electric sparks.
A grounded system is an electric connection system which ensures that one or more conducting point which usually is the Neutral point of electric switches are solidly grounded or though a current limiting device. This will prevent damage of properties or other Electric appliances as a result of over currents etc.
