- Q: I live in a home that is 50 plus years old. All of the electrical outlets in the home are the out dated 2 prong plug ins. Are there any safety issues associate with replacing the outdated 2 prong outlet with a 3 prong outlet to power a metal halide high bay light fixture with a 400 watt ballast? The wiring in the wall is also outdated and does NOT have the up to date 3 wire electrical supply.
- No the electrical code requires a ground. Run a separate ground wire to it from the metal water line coming into the home or from the ground rod from the electrical service or Telephone ground rod.
- Q: Upstairs toilet water seepage for a long time, my house is a large number of walls, has been unable to discuss the argument, the recent short circuit, and suspected to be the reason for water seepage, but upstairs and his insistence, even if there is a leaking can not affect wire. Because of this ignorant, so here to ask you, leakage of water will lead to short wire inside the wall? Thank you for answering. Question added: 1: is the old house, the wire is replaced seven years ago. 2: upstairs tenants insist on not admit leaking, but also invited his decoration master to see, they say no matter what the situation, even if the water leakage will certainly not lead to short circuit. For his argument doubt, so I would like to ask, is not any case, the leakage of water will not be inside the wall bubble to a short circuit? More
- BV line is a single strand of hard copper wire, BVR that is copper core cord.
- Q: I was just wondering is all electrical high voltage lines including low voltage is isolated to prevent electrical shock.
- Some do and some don't ! High voltage power line that runs at 20000 volts to 50000 volts is a bare wire. Lower voltage street line from pole to pole (about 5000 volts) is also bare wire. After step down by the small street transformer then feed to the house 240 volts is insulated wire. All the AC wiring inside the house carries 120 volts and 240 volts is insulated wire. Most electronic circuit board has printed circuit which has hundreds of bare wire.
- Q: Can electrical wire from a 50 ft drop cord be used to re-wire the lights on a old car with a 12 volt system ?
- Yes, but it is not oil and gasoline resistant and the oil base products used in the vehicle will dissolve the insulation cause a fire hazard. You need automotive rated wire because the insulation will resist oil and gasoline and the high temperatures of an automobile.
- Q: I want to install two separate outdoor lights. How do I do that from one wire? How can I make one wire into two wires and what would I need? Thanks.
- this can be done with a external water proof junction box, be sure you know what you are doing, you could put your self and the building at risk.

- Q: does the term, home-run refer to, and what are some other common terms with a brief description plrease? thanx! jk.
- Home run means it goes straight back to the panel. I have done some wiring in my house and I try to do it all with home-runs. Its far simpler and you have fewer chances to screw up. For example, you want a new receptacle on your patio. You run a wire from the panel straight to the receptacle. No boxes or splits. That is a home-run.
- Q: Home decoration to use much of the wires, such as light lines, sockets, air conditioning lines, refrigerator lines
- Own house or more than 4 flat, safe first! Do not consider that little investment
- Q: I do not want to break any nyc code law.
- Non-metallic (NM) wire also known as Romex(brand name) is used in residential wiring but must be installed according to the National Electric Code (NEC). As it says in the first section of the NEC, All codes are subject to the authority having jurisdiction Which means your local electrical inspector has the final say. Your best bet would be to call your local inspector and ask him or her if you can use NM in your application.
- Q: What is the difference between a radiation wire and a wire without radiation?
- Metal rail or metal tank within the total cross-sectional area of the wire should not exceed 40% of its cross-sectional area, and the metal box containing the flow of wire should not exceed 30 16mm? wire diameter of 8mm, plus the maximum cross-sectional area after the insulation are: 502mm?; truncated area = (502 × 2) / 40% = 251mm ?; trunking a × b = 251/12 ≈ 209mm, × 12 of the trough as well
