Web“earthing” is used instead of “grounding.” Plumbing (including bathtubs and sinks) used to be solidly grounded. But now it may be not connected to ground because of the use of plastic pipes and drains. When faults occur in electrical systems, those faults are frequently faults to earth (ground faults). To better understand the grounding WebThe National Electrical Code (NEC) requires that all normally non-current-carrying metallic objects in a given structure be bonded together to form a single common system that is at the same potential. This includes the steel rebar in the concrete foundations. We see in Article 250.50 the mandate that all electrodes listed in the code (steel ...
