Bonding impedance
WebDec 1, 2014 · Theory of Equipment Grounding Impedance. Richard Nute. December 1, 2014. Values for grounding impedance appear in many standards, including UL 478 and 1244, CSA C22.2 No. 0.4, and IEC 601 … In a system with a grounded (earthed) neutral, connecting all non-current-carrying metal parts of equipment to earth ground at the main service panel will ensure that current due to faults (such as a "hot" wire touching the frame or chassis of the device) will be diverted to earth. In a TN system where there is a direct connection from the installation earth to the transformer neutral, earthing will allow the branch circuit over-current protection (a fuse or circuit breaker) to detect the fault ra…
