ECN Forum Forums Safety Discussion and News Occupational Safety Discussion Won't shutting down the power cause problems?

OSHA's rules are not applicable to a one man shop. If the HI is working for himself, does he need to turn the power off?

When working for a larger company, does he have to comply with OSHA requirements?

Pierre,
You are correct that the OSHA rules only apply to employees. If the HI is self employed, the rules do not apply, but the danger remains the same.

Hey trumpy why are short-circuit faults getting higher?

I'm confused, if the panel needs inspecting, why is it already energized? Her we LOTO every thing.

Gidday feather,
Welcome to the group.
The reasoning behind that is on-going inspection, it's looking at things like potentially loose connections, wires that are overheating, just things like that.

Surfin,
Fault currents are getting higher, because the lines feeding installations and transformers are getting bigger.
Bigger wire size equals less impedance equals higher available fault current.

Ipscc = Vsource/System Impedance.

Thanks trumpy I had a 1600 amp ge drawn-in breaker go to ground as I was racking it on to the bus.That thing went off like a bomb.I was damn lucky I bolted the door shut.Walked away without a burn though I was definetly carbonized.So I can relate to high available fault currents.It takes a lot to wipe out the utility's fuses.

Surfin,
I had a UK Telecoms tech close a 6.6kV trailer CB one day and I caught the worst of it.
Straight onto a fault.
He was told to stay out of the way.
Not that I'm against UK Telecoms staff (Paul).
Took a few hours to see again though.
