I was taken aside on a job-site today by a new Apprentice working for a Sparkie here in town.
I was there making sure that there was room to put a pole and transformer up.
Anyway, one of the builders actually told me of this guy and we went and sat in my truck during Lunch.
He was a little concerned at the "Electrician's" method of finding circuits in this new house that was under construction.
After he told me, I wanted to run in there and..... well need I say more.
Upshot of it all, was the Electrician would liven a breaker and the Apprentice would touch the Phase and Neutral wires together and if there was a flash the Electrician would know he had the right circuit.
I went and had a quiet word with the Electrician and found out he had no Practicing Licence, to do the work in the first place.
By then one of the Inspectors had turned up, I left it to him.
I'm glad the young fella actually had a chat with me, this guy could have killed someone!.
Sorry about the rant, but....
