Hello;
277/480 3ph grounded system with no neutral loads served,system is grounded and bonded at first disconnect, EGC taken to secondary XFMR with secondary XFMR 480/120-240, if secondary XFMR is grounded and bonded seperatly wont this create multiple ground fault paths for original system between the two grounding electrodes. Can the secondary neutral just be bonded to primary EGC.
Thank You: AZJoe
