You may find this short article helpful in locating wires and troubleshooting problems since the major strategy in finding and fixing electrical problems is to locate a position where there is no problem and then keep scaling down the gap between that point and the problem point.
When working with an electrical problem, increase your safety by taking simple safeguards. Turn off the breakers to any section in which you are working. Use an outlet tester to make certain the power is really off before touching any wires. Electrical repairs tend to be more fun throughout the day becuase it is easier to see what you are doing Trying to squeeze in an electrical repair during the late afternoon or evening could make for a long night of juggling torches, extension cables, ladders and tools. Waiting 18 hrs to begin the following morning is almost certainly the best plan.
When fitting a switch, make certain it’s for the correct conductor. You don’t want to be fitting a light fixture using a switch on the neutral wire. If you are lucky, when you turn the breaker on, all that happens is that it's going to trip and frighten you. Renewing existing components is generally easy enough but, put objects back the way you found them and you ought to be ok. Conversely, adding new equipment can be a tougher task to take on. Be especially careful with any wires that aren’t white, grey or green. In a single home that I worked in, some very strange electrical work (probably not done by an electrician). I had the horrible surprise of finding cut (but not capped) black and red wires. It is my opinion they were probably planned for a hot tub installation. I applied a quick test on them only to find out these were actually live and giving out 220 volts. Frightening to say the least!
My advise is that if you’ve inquiries on this subject matter, at the very least visit a book store or perform a little research on the web and buy or read the NEC guide for residential wiring. An electrician may cost you some cash, but a do-it-yourself repair could cost you your property and/or your life.
Discussions about the better brand names of tools can get incredibly heated, with well meaning people holding very firm opinions. My own individual feeling on this subject is that it is basically almost impossible to know for certain which is the better brand. Even with the wherewithal of a full testing laboratory, the developing and design specifications vary so often, that the results are out of date prior to publication. If you happen to stumble upon a sale where you can buy another brand cheaper, then by all means do it.
The proper tools can make the job go considerably more rapidly. Though many brand name tools are costly and there are lots of options. There is trade-offs between price and quality. If you don't have the knowledge, it may be awfully hard standing in the hardware depot trying to determine what you really require. My foremost goal with this article is to enlighten people to this one major point, if you are not sure in relation to what you are doing with electrics then leave well alone and hire an electrician.
