I have an antistatic wrist strap and i wan to know if i can put the aliigator clip into the third prong on my grounded outlet. Dont tell me to clip it onto the metal part of my case, its all painted. SO can i put the clip into the third hole in the wall socket?
Yes, you can clip it to any ground wire.
But be aware that, although you are grounded, the case my not be. You could still be working at different potentials.
Is there nothing inside the case that you can make contact with? Screw an un-painted screw into any hole and use it?
