N.E.C Grounding Code for Arials
No. 10 for Copper..
No. 08 for Aluminum (Understandable Because of Resistance) No. 17 for Copper Clad Steel? Why do they allow such a small conducter? Is steel able to handle higher voltages like lightening for a longer perioud of time? (nanoseconds I would think) Thanks, Jeff P |
