Somewhere, can't remember where or when but fairly recent, there was another discussion about this.

Apparently the real problem of DC on the mains is that an RCD is saturated, only 30mA, and won't work. That is nasty.

There is a B version of an RCD that can cope with limited DC.

If I can find where I read it will post more, but it is of importance.
