Then there are the houses that use the cold water pipe as the main ground for the electrical panel for the house. Man oh man the blue fire that happens if you happen to cut that SOB with a 240V dryer or stove or even just the 120V stuff turned on anywhere in the house is Wicked! Just turns the pipe cutter into instant slag. I make 'real' sure where the electrical panel is when I cut a cold line and half the time put a set of booster cables across where I want to cut if in any doubt.

Listen, first of all, you are not stupid just because you do not know something, that is why you ask questions. Stupid is not even asking the question. Some multimeters can be a bit confusing but generallt you use one set of lead connections for volt and ohms and another for AMP if your meter supports that (those terminals have a shunt accross them internally for current measurements) You always what to use 1K range on ohm meter when checking light bulbs. Also transformers generally rarely fail and when they do there is usually little doubt because they will appear or smell burnt. Only a few things can kill a transformer. The first is overloading it and it overheats and insulation in winding break down and it shorts out internally. The second is that a winding open up internall which is really rare in a power transformer and the third it insulation break down from time and heat which cause it to short internally. Properly sized for load a power transfomer can live many many years. ----------------- TheSnoMan.com |

Obviously you do not because the reason they use reduced voltage lights around pools and outside is to reduce threat of shock. Only a idiot would sugeest to upgrade a 24 volt pool light system to wall voltage. It does kinda fall in line with other comments or ideas you post in other areas so this is no surprise. ----------------- TheSnoMan.com |
