Seriously, do you believe " High current and low voltage is the

danger"

If so I'll continue to work with you.

Do you know ohms law?

Do you understand that for a fixed resistance, current is totally

dependent on voltage?

No, he doesn't.

It seems he doesn't but I'll wait for him to respond.

He also doesn't seem to understand that 277VAC service

has the potential (G) to deliver way more than the 5ma the human body

model responds to (adversely).

Yes, his writings would suggest that, when he responds, I'll see if I

can walk him through ohms law, to show him how it works.

How can you show anyone what ohm's law does if you can't even accept that transformed higher voltage means lower current and vice-versa?

You haven't completed that sentence.

If you are distributing power, a higher voltage line can deliver the
same amount of power at a lower current than a lower voltage line.
But you will be killed by a 330kV line easier than a 120 volt line.
That ay be why they put 330kV lines on tall towers and put 120 volts
in your house.

If you are talking about connecting a 240 volt line to your left hand
and grounding you right hand vs doing the same with a 120 volt line,
more current will flow with higher 240 volt line.
I got into the discussion when you said,
"Overhead commercial lighting voltage is 277 so its less current and
less dangerous,"
So to rephrase you said, 277 volts is less dangerous than a lower voltage.
Do you still think this?
