I'm putting in a new switchboard which will be fed via an existing 13.8 to 208Y/120V pad mounted transformer. I don't know how old it is (yes it might be a good idea to take a look) but at this point I'm told by the onsite electrician that there is no indication of it's impedance on inside nameplate.
This same electrician assures me that there is no way that transformer has an impedance lower than 4 percent. I know this is probably correct. Yet, it seems to me, anything is possible! How good an assumption do you think this is?
Thanks,
Mike
