- Q: I would like to know what the standards are for Big Fat power leads being exposed, isn't that an OSHA hazard? What are all the volts, that need to be covered by a floor wire covers, so nobody will trip in them. Anyone know about this any helpful information regarding wiring safty on the job? Can a place be shut down for employee safty reasons? What are the major voltages in America? Honest and non- rude opinions Please Thank You
- In areas where untrained personnel will be, no leads should ever be exposed. The typical covering to a machine, especially a permanently mounted machine running at 480 VAC, is flexible conduit to a disconnect and then EMT or rigid conduit. However, cord connected equipment is not uncommon, even at 480 volts, especially if it is mobile, like portable pump stations. The difference between a cord and exposed leads is a cord has all of the leads tightly held together with a thick outer sheath of rubber protectiing them from damage/contact. Exposed leads are the individual wires that are run in conduit or are found inside of a cord. The leads will have their own outer covering, typically harder than the rubber you find on the cord because it is a different material, rated to contain the voltage running on the actual wire (most often copper or aluminum). Standard voltages: 120/208 120/240 277/480 Anything above these is not a standard that most people will be exposed to. It would not be typical to immediately shut anyone down. Normally a citation or warning is issued with a time frame for correction and reinspection. Both your local fire department and OSHA are very concerned with exposed live wires and either of these will normally respond to a complaint and NOT divulge who called, if you so stipulate when and if you call., though not for what many people call low voltage, the voltages many doorbells, intercoms, phones, audio/video, etc., may run at (perhaps in the 12 to 50 volt range).
- Q: I was doing some renovating on a house I just purchased and was taking apart the ceiling to work on some electrical wiring. As I removed the ceiling, I found mouse droppings in the ceiling. I took down the entire ceiling and found there are place where the mice chewed through the insulation and I have a bare wire. Is there a way to repair the wire or should I replace the wire? Thanks.
- Replace the wires and save yourself some trouble or better still save a life.
- Q: Hi, I have installed a 200 amp service entrance. I am in the process of attaching it to the grounding rod. What size cable should I use? I was told that a size 8 wire is ok, as long as it is protected. However, I was also told that I should go with a size 4. Can I use the protected 8 or am I better off going with the 4? Are there any advantages of using one over the other? Thanks for your time,pb4sc
- you are much better off with the 4 it will hold a larger current
- Q: going to roll out attic insulation between the ceiling joists. what do I do when I come across wires that go through the joists? Can I roll the insulation over the wires or should I cut it and leave the wire exposed and start the roll again on the other side of the wire?
- Heat is the enemy of the insulation on electrical wires. When you put insulation over the wires, you cause the wires to get warmer, this increases the resistance of the wires which then causes line loss or also known as voltage drop. Cut the insulation or put it under the wires, then tape any cuts with the wire exposed. This is the proper way to do it. Most insulators, just roll it over the wires, but it will change the amp rating of the wires. This may or may not be a problem.
- Q: I have an old house (built in 1962) and after testing all of my outlets, have confirmed that none of them are grounded. The house is made of brick, so it would be extremely expensive to run new circuits through the house. I really only need 1 or 2 outlets to be grounded so that I can protect my expensive equipment from damage. So what I wanted to know is if I could buy a spool of 10 gauge solid copper core insulated grounding wire, drill a hole through the brick behind the outlet, connect to the outlet and run the other end of the wire around the outside of the house to the main box. Would that be safe? Would it hold up to power spikes?
- Yes you can do that but you don't have to go to the box if you have metal cold water pipe. If the pipe is plastic then yes but you cpuld drive a metal stake into the ground 6 feet and ground to it. you can get grounding stakes at a hardware store or electrical supply so find out which is cheaper wire or stake. on the wire it doesn't have to be solid just #10 and daisy chain it. go from the farthest box outside to the scond box then to the Elecrtical supply. I assume you have a slab floor if not go to the basement and across to the box or attic to the box. An alternate solution is to just change the sockets and don't ground them. it is not really necessary most equipment has planned for an ingrounded socket. you change the socket so it will plug in without cutting off the ground pin. For GFI it is necessary to ground it(kitchen and bathroom). different states have different codes.
- Q: I have installed ceiling fans before with no problems until now. I just moved into this old duplex where the ac is crap and it's hot as balls outside. I finally break down and get a ceiling fan to install. So I get up to the light fixture,pop it off and to my surprise there aren't enough wires. There are four wires coming from two lines,both sets are black and white. The black wire from one line is connected to the light and the white wire from the other line is also connected to the light. And then the other black and white wires from the seperate lines are connected together. And oh I almost forgot there is no ground wire in sight. What do I do here???

I just moved into this old duplex where the ac is crap and it's hot as balls outside. I finally break down and get a ceiling fan to install. So I get up to the light fixture,pop it off and to my surprise there aren't enough
- Q: i had to remove a couple of light fixtures for some drywall repair i was doing. the fixture was hooked up to a hot-neutral aluminum wiring AND a hot neutral copper wire. i think the other fixture had same wiring. have these fixtures been pig tailed? if not, what should it look like? thanx!
- The only way to connect copper to aluminum and limit the possibility of fire is to use split nuts which can be bought at an electrical supply store. While you are in the store, get some anti-oxidant. The main problem with a split nut is that they will be large and you will have at least two of them per box and most boxes are too small for this. Wire nuts are not the thing to use. There is a method that is approved for this, but the electricians have to be specially trained and that cost a lot of money, so they avoid it. They have to rent the tool to do it from the manufacturer and they want something like $8000 as a deposit to rent it, so an electrician who can do it will be expensive.
- Q: i have a Husky 5,000-Watt Generator i change the circuit beaker switch on it know i forgot how to put the new one on there 2 line terminal and 2 load terminal , 2 blue (hot)wire and 2 white(common) wire where do they go
- The line side goes to the generator and the load side goes to the output sockets.
- Q: i dont know if this is to confusing to understand but i was jw if i could make heat using electricity and electrical wiring that can stay warm and can heat things up and that is rechargable that i can put in a coat or anything fabric or shirts or shoes can anyone help me out with this?
- Current through a wire does cause heat. Look at the standard light bulb or electrical heaters. What you are proposing can be done but be sure you know what you're doing - we don't want you setting yourself ablaze.
- Q: can please any one let me know the meaning of db written on electrical wires
