I did a very bad thing... (zap!)

Exactly. I always meter anything metal on my DIY projects that I will be touching in reference to ground and verify there is 0 volts.

Glad your ok! Sounds like you brushed your self off and got right back up on the proverbial horse.

Measure the resistance between exposed metal and earth ground. Zero ohms (ish, most meters don't read zero).
 
When I used my drill to drill holes in the fridge to Bolt the tower down I hit a hot line when I put the bolts in it connected with the bolt and seem I used rubber it never grounds the tower. When I put my hand on the tower and then the stainless fridge, I made the circuit and te breaker did not trip till 2-3 min later.. Dame old apartment.

Breakers don't typically trip in the case of electrocution. The human body won't conduct enough current to trip them. That is why:

1) ALL exposed metal needs to be connected to the earth ground conductor (so if a live wire touches the metal the breaker WILL trip), and
2) GFCI's are used in wet locations (they will trip if less greater than 0.005 Amps get shorted to earth).
 
Glay your OK. Mishaps in the home are quite dangerous. I know. Been there.
 
Wow, Glad you are OK. Like someone else said some nice insalated tap handles are in order. People will ask why while they are pouring a beer and you can tell them why then.
 
Well I finished it.. Put 12 psi on the beer and rocked it for 30 min. Nice and carbonated on full glass 2" of foam. I think I have a keeper
 
Glad your ok. I got hit last week too. I was pushing in an electrical outlet after putting up the drywall in my ferm chamber. Ground wire was in the way of the screw just a little bit. So what did I do?? Go to push it just a little very carefully with my other hand. Zap....In the right hand out the left. I'm sure my heart skipped a beat??? Luckily I was fine afterwards. Stupid me should have had the breaker off. My old man said I would probably be dead if I was in europe(220 V). Lesson learned....

This will also work but not in every case. Many years of hands on experience and a degree in electronic engineering has proven that a voltage reading is more accurate than a resistance reading for this type of application. For example.... If you meter resistance in reference to ground and the supply is coming from the secondary windings of a transformer, you will read almost a direct short to ground through the transformer winding (provided one side of the secondary is grounded). But if you power that same circuit up, you will read a voltage potential in reference to ground. Mind you, this is the same circuit you just read just measured under an ohm in reference to ground. I design elevator controllers for a living and am very comfortable with the electrical information I provide. Measuring resistance to ground can still get you electrocuted. Also reading an open to ground doesn't necessarily mean the component being me assured is energized. I still think a voltage measurement in reference to a known good ground speaks volumes.

Not wanting to start a pissing match, just would like to present my case.
 
Please tell me you don't have a name for your bar area yet:

Lightning Larry's
Sparky's Saloon

etc... ;)

Glad you're ok!
 
Sounds like a good trick to play on your teenager and his friends who steal beer out of the tap! I would turn the voltage down a little though lol.
