I was told: If I place a scope probe across an AC outlet, I'll blow up the
probe because I'm placing the ground of the scope probe onto the AC outlet
and shorting it to ground.
That makes sense because the scope probe's ground is Earth ground and I'm
shorting 120V to ground.
But if I place the scope probe's ground on neutral and the scope probe tip
on hot, then I should be OK, correct?
Also, I can float the scope but risk being electrocuted because it will
float to a 120 potential.
