The two issues in protection is a) get everything to ground and b) keep the ground from jumping The rule is to make the shielded wiring harness to appear as a lightning conductor. So, the use of shielded cables forming an extended Faraday cage is a must. Disconnecting the shield at one end of the cables is a violation of this rule. Use a PEC to make the shielded cable robust against high currents. Kai |
