Anything wrong with grounding metal conduit to a cold water pipe ina 2-wire house?
During a kitchen remodel in my mom's circa 1948 house (post WWII made out of reinforced concrete!) with 2-wire electrical and metal conduit, I mentioned to my brother and nephew that, since it was exposed, it probably wouldn't be a bad idea to ground the wiring conduit to a cold water pipe, thereby grounding the entire conduit run and at the very least making grounded outlets work properly.
They reacted in horror saying it could cause a fire or even worse. I said that at least you'd know if you had a short circuit because the breaker would trip and touching something metal wouldn't kill you.
Ok, who's right here?
BTW, he's my older brother so I just let it go.
