My understanding is when you have a isolating/safety transfomer installed you will rater use a isoloc
On a normal installation the neutral/earth wire is connected the metal parts in the home/installation aria . That then makes you shock if you touch any earthed part and live

In a safety transfomer circuit the not one wire is connected to metal parts so if one wire touches the metal parts it will still not make a short . The isoloc will pick it up and cut the power

I'm not very familiar with isoloc earthing system, I know it's one of the many high impedance earthing arrangements they use in industrial applications. I think it's more about monitoring insulation breakdown and, rather than aiming to clear the fault withing a very quick disconnection time like domestic installations, a fault causes an alarm and the fault is manually cleared. I think Isoloc is more about monitoring and repairing before a full blown fault occurs.

Have you worked with isoloc systems Yuri?

[Yuri]

Yes I have
