Yep think that is it.

In principle it should not matter what 'polarity' there is in the socket/plug ... neither side should be connected to anything you could touch. In principle. Some people wire 'earths' to the 'center' or 'neutral' depending what place your in. That is not safe unless wired correctly - I'd not trust it unless I checked it myself.

Best practice is to have a separate 'earth' connection that goes to anything you can touch. And goes to 'earth' - metal pipes into the soil or bars driven into the soil.

Good Luck with the house wiring. I've seen lead covered ceramic insulated wiring in use ... removed on sight! Probably 1920 vintage? The house also had lead plumbing pipes for water ... .. it was ok, they were for the cistern (from the overhead flushing tank) not the drinking water.

-------------- Don't trust that cable guy who said "reverse negative polarity" !
