Need clarification / conformation on the voltage readings to ground, and suggestions / solutions.
Knowing the secondary 240 line to line should be 240v and line to ground should be 0v.
Found a voltage reading to ground on a disconnect and was able to determine the circuit that was causing the fault.
Removed the wiring from both the disconnect and wiring to the circuit breaker at the panel board and locked out both. Have not been able to troubleshoot further at this time.
Now another disconnect is reading to ground. I am not able to secure this circuit, and know this needs to be addressed before another fault may occur. Can someone explain what may occur if this is not repaired or resolved.
The location has an old CH V48M24T12F is a Delta to Delta transformer. Eaton’s tech support sent me this “Since this transformer does not create a neutral there is nothing to ground and the 240 VAC does not have a reference to ground and you should not see voltage to ground, only line to line.”
I am suggesting the ungrounded transformer be replaced with a grounded system.
Thank you,
Robert
