Default Re: Another unusual plug and some other questions

Thanks Lucien, a mine of information as ever.
There is a hole in my library between 1910 and 1940 when a lot of changes took place.
You talk about non-reversable two pin plugs being acceptable, would this have been with a TNC system (ie. Live and PEN), or insulated items only?
I know the 12th edition (1950) mentions single pole fusing, and a permanent connection between neutral and earth as in TNS.
It's interesting you suggest that the regs lagged behind the manufacturers.
Rob.
