i dont know i cant open it but it is an OBIT

Measure it with an ohm-meter. You should have NO continuity from one side to the other.

it has to be isolated because hv supply are pretty dangerous. i had the experience very painful the some veins in my right hand were damaged

It doesn't HAVE to be isolated, it MAY be isolated, or it may be an auto-transformer.
