Irrr..... If there is a short, it might not be grounded. You touch, you become the ground. ZAAP!<br><br>If you have a doubt, don't trust anything electrical. Why do you think I don't trust computers further than I can throw them? (PDAs don't count- they can be skipped on water. )<br><br>If a breaker goes, it may have been from a surge outside or inside. Check everything, and if you can't find anything that looks likes signs of a problem (melty spots on casings, scorching, the smell of o-zone), reset it. If it throws again, you've still got a problem. <br><br>But then again, my electrical knowledge is all from electronics, little stuff.
