what is typical RISO value?

A leakage of 4ma is not yet a safety hazard, but it does suggest that somewhere in the system, either in a panel or at a wiring connection, or even along the wire somewhere, there is more leakage than there should be. Possibly the airtight seal of one of the panels has broken. Possibly you have a wire which has been abraded and is close to
