When running triplex to a 240 panel and then installing a ground rod at this panel would you have to bond the neutral and ground again. It seems to me that if you didnt and you had a ground fault it wouldnt trip the breaker because there is no egc back to the main panel and it would put voltage on the electrode and the bonded panel. I know its been said that you only bond the n and g at the main disconnect. but maybe there is something im not getting here
