Grounding metal control panels

<< < (3/3)

APFelon:
I'm sorry, I thought I was clear.

I wired the 110 through the FG as a lazy "shortcut",  thus electrifying the panel, the coin door, and everything else that the FG wire ran to.

So, when a customer touched the panel, they got a shock.

You have 3 wires running in to a game through the line cord: A black, a white, and a green. Typically, the power runs trough the black and the white, with the green as kind of a "catch all" for static and the like. That's why it runs to various metal components throughout the game (the panel, the marquee light housing, the coin door, the monitor mounting frame). I ran 110 through this green wire and it electrified all of it. So when someone touched the panel (or the coin door, monitor mounting frame, marquee light housing, etc) they would receive a shock.

I clearly suck at telling stories, so never mind.  :P

Your diagram is fine. 

All of the green wire runs to the ground, you don't have to ground it separately.

Shocks can be caused from lots of things, like static or a malfunction, or a frayed wire.

Grounding the CP (every metal control panel I have was grounded) is fine.

Sometimes the ground is just on the metal frame around the CP.  It's just a wire.  It can go to the FG.

It makes the risk of shock 0.
