I see a law suit coming your way from "random-electrical-advice-off-the-internet-I-didn't-understand-which-killed-my-mother-lawyers4u.com"
By the sounds of it you follow my mantra of "If you're not absolutely sure get an electrician in".
All seriousness @Vendivorex appreciate you have a retired sparx in the family but messing with this if you're not completely sure can kill you.

Thanks for the advice.
