@coliver I hire sparky's because I know what 120v across the chest feels like.
This thread is giving me the hebejeebies, I'm exiting stage left.
Yep... I generally do too unless I can make sure the breaker is off at the panel. We had all the breakers to the upstairs off when doing this and thought we were good.... turns out that wasn't the case. Lesson learned.
I do 90% of my electrical work with the power on. How the heck am I supposed to see what I'm doing if the light's off?!? Besides, 110V just tickles a little. I accidentally channeled 208V one time. I'd like to avoid repeating that one.
My folks had a 220v stove... and the genius that installed it grounded it to the metal sink pipes. So if the stove (or oven) were on, and you were touching the stove and sink... yeah. Let's just say we have many electrifying experiences over the years.
Pops finally replaced the stove and fixed the ground, lol.

@dafyre Was that a 3-prong 220 plug? Trying to understand why the ground would be live.

I honestly don't know. But that thing hurt if you touched it the wrong way... I had grown up and moved out before he finally replaced it, lol.

I have a 208v appliance (screw auger) that is ground over the neutral line. I did a ton of research when setting it up and apparently it is pretty common.

Hopefully not getting zapped by it, lol.

Nah, I tied it into the house ground independently of the neutral bar. On a recommendation from an installer. I haven't gotten zapped yet - although it may happen in the future.

Nah... You done it right tying it to the house ground. You have to try to get yourself shocked that way, lol.
Just don't ground it to the kitchen sink, lol.

@dafyre This is what I like about ML. Not only can I get advice on IT, I can get advice on home maintenance and electricity.

I"m not an electrician... I have a (very?) basic understanding of electronics, lol.. Following my advice may have the following side effects: Nausea, upset stomach, loss of feeling in hands, loss of feeling in arms, loss of feeling in feet, empty bank account, sudden muscle spasms, electric shock, cardiac arrest and even death.
In the event you experience such side effects it is too late to call your doctor... Sorry.

Yes, neutral and ground do go to the same place, anyway. The difference is at what point they get there. Your typical "ground" that you're used to is to protect you in the event that a live wire on the device accidentally makes contact with something on it that you could touch. If it's grounded better than you are, you don't get zapped. The neutral line is there to create a sink for electron flow for the actual power. Lots of 220 appliances used to use those 3-prong plugs, which is L1, L2, N/G. Most modern setups have 4 prongs: L1, L2, N, G. All neutral lines go to ground in the end. If you're getting zapped, the shell of the appliance is becoming live and is itself not properly grounded, or maybe the shared N/G is being tied to the chassis. When you touch something well-grounded, while touching something with its chassis grounded to a shared N/G, you become well grounded... and get zapped.

Remember to test wires with the back of your hand, so the electricity doesn't make you clamp down and keep you getting shocked

Your ears work just as well for that... just sayin'
