Can I use myself to ground a circuit? Answered

I'm working on a project that requires a large ground connection, so I'm thinking to connect it to the handle so the user's body acts like the grounding. Will the user receive any kind of electrical shock if I do that?

Sure you can the emergency room is full of people that have done it.

I would not recommend going anywhere near or over 0.004 amp or you could be visiting the morgue.

Then of course there is the discomfort of AC voltage, I have been hit with 20,000 volts at 0.002 amps.

Believe me I learned some new dance moves that day.

DC voltage is less painful but you seize up and can't let go of what is electrocuting you.

But sure you can do it, just let me know when you do beforehand so I can send flowers.

Years ago I had a threshold of feeling test where office volunteers would place two adjacent fingertips of their predominant hand on copper buttons that would under user variac and transformer isolation present an AC voltage and they would report the threshold of feeling current that was measured...

Most Americans could detect in the range of 1ma to 7ma.. A Japanese friend could detect o.4ma but a 34 yr old electrician could not detect anything a fact made relevant when he told me he used to place his finger in a light socket to test for power an only after licking his finger first !

My wife thinks I nuts, but I check the coil of lawn mores and other small engines by how painful it is shorting the coil out with my hand. Yes I have been electrocuted more than once. But I am more accurate than a multi meter and healing is cheaper than buying a new meter.

How challenged gravitationally you are ??

Most people antennas or noisy pith-balls are.

Depends on the application, but it is not recommended. I used to use myself as a ground/antenna when I was messing around with crystal set radios a lot as a kid.

Nope, I believe you have too much resistance

First of all we need more info's

While connecting yourself to the ground wire, you may be not grounded (wearing something insulate you from the earth). And if you are and a significant current pass through you, you will get electrocuted.

I would use a 3 wire power cord. They have an earth connection in them.
