Question that I hope someone can help. New home construction. SUBPANEL has Bonding between Neutral and Ground.
Service Panel and SUBPANEL are next to each other (the 2 boxes are about 2 inches apart). I also read this from Taunton, Section 2 "Subpanel wired improperly": http://www.taunton.com/finehomebuil...ages/h00009.asp
The Main Feeds to SUBPANEL are controlled by GFI breaker in the Service Panel.
The question is that: having read all these NEC code issues and the recommendation is to remove the BONDING between Neutral and Ground.
Can someone shed some light on this topic?
1. If Neutral Wire from Service Panel to SUBAPNEL is never opened , it is NOT a risk to trademens touching the plumbing system, correct?
2. If the Main Feeds to the SUBPANEL are protected by a GFI breaker, is there a need to disconnect the "BONDING between Neutral and Ground"?
3. Also if I understand the NEC code correctly and the Groung problem correctly then even in a normla home with ONLY a SINGLE service panel (NO Subpanel), then an opened Neutral before the service pabel can casue this problem of current flow through EGC. Is this correct?
Thanks in advance.
