Home / Grounding resistance value of the capacitor in the distribution box
Grounding of the units: Attach a ground wire from one of the threaded studs (A) at the bottom of the housing, to the mounting plate (B). Basically, the idea of bob-smith termination is to provide a sink for common-mode noise that may transfer from the PHY side to the connector side. The National Electrical Code (NEC) defines system ground as a connection to ground from one of the current-carrying conductors of an electrical power system or of an interior wiring system, whereas an equipment ground is defined as a connection to ground from one or more of the noncurrent-carrying. The information provided in this document contains general descriptions, technical characteristics and/or recommendations related to products/solutions.
