Bill:
Your original question for this topic was about GFCIs for bathroom outlets, etc. With all the details of our grounding and whole-house ELCBs, I haven't yet gotten around to explaining bathroom outlets here.
This is one area where our IEE Regs. have been very specific for many years. Normal convenience outlets - whether GFCI protected or not - are not allowed in a bathroom. Period.
The only socket (receptacle) permitted is one intended for feeding an electric razor. These are non-grounding sockets designed to take a plug with two round pins. The plug is actually our old ungrounded 5-amp type which was widely used before the introduction of the new universal 13A plug (and continued to be used long after).
The razor outlet unit contains a 1:1 isolation transformer, providing the standard 240V but with no ground reference. In many cases, the xfmr and outlet are incorporated into a strip light fitted over the mirror.
Similar lights with a razor outlet but no isolation xfmr are also available. These are intended for non-bathroom use (e.g. bedroom vanity unit), but because they're much cheaper it's not at all unusual to find them in bathrooms anyway.
With the "Regs." not being legally binding and no inspections, violations are not uncommon.
