Patching A Cabletv/internet Ground Line

I want to run a Cat 5 line from my phone box outside to a jack inside to connect my phone and DSL. Right now I just have a regular phone line for both and the phone company recommends running a new line because the internet is always slow and I can't call out on my phone.



How do I know which wires to hook up outside?

I recently switched over from AT&T phone/cable/Internet service to Cablevision. 



The problem with both services is the coax cable coming through a hole in the wall from outside and then a phone line from their modem stapled to the floor board and tied into the phone outlet inside.  Then there's my phone lines, the coax cable to the TV... It's a disgusting mess.



I'd like to install a combination phone line and cable outlet in the wall and get rid of as much loose wiring as possible.  The phone line would come through the same area as the cable and I'd wire it on the other end to the main box outside the house.



I have no experience with this so my question is can I take the phone line from the Cablevision modem and simply plug it into the outlet and get all the phones in the house to work or does it have to be hard wired or piggybacked inside the outlet?

i have seen on this site------------------------------------------------------------120/240 for houses:  120 is line to ground, 240 is line to line



so got the point from this point that we have three phase connection so

120 is phase voltage and 240 is line voltage



but line voltage is=squareroot of 3 *phase voltage and (240 is not equal to sqroot of 3*120)

please send the answer on  ---------   as soon as possible
      

We need to have a new water line put in from the meter in the parking strip to the house. We've recently had a new electrical panel put in and the electricians pounded two grounding rods into the ground outside our house. Because of this, will the house be just as well grounded if we get plastic pipe as if we get metal?
      

I am going to install some can lights throughout the house soon.  I have one light in the center of each room that is already wired up.  I will be patching the existing light boxes up to run the new can lights, utilizing the wiring that is already present. 



When hooking the extra lights up should I use 12/2 or 14/2 wire for running them in parallel?  There will probably be no more than 3 or 4 can lights per room ran with CFLs.  The current lights that are in each room take up to 3 bulbs per fixture.
      

Today I was fixing the water valve to the washing machine, and to get access to the water line, I had to disassemble an outlet. To my shock (no pun intended), I discovered that some moron bootlegged the outlet by connecting neutral and ground together.



Now I'm concerned that I may have this elsewhere in the house. What is the best way to test for this? Obviously I will see 120 V from hot to ground in any case, so that doesn't work. Continuity between neutral and ground is normal, because they are connected at the main panel; I measured the resistance between neutral and ground at an outlet close to the main panel, and it was virtually zero. But that doesn't meat it's bootlegged.



I don't really want to take each outlet apart. And even if I do that, how would I know that the moron didn't connect ground to neutral somewhere inside a wall?



Thanks,
      

i have 3 switch sets in my house that are giving me absolute fits.



#1  kitchen switch, controls the light over the outside door




    Code:

   

3 sets of lines coming in,



line from the breaker panel (power)



line to the ceiling lights 



line to the outside porch light.

i cannot get this 3 line to work without tripping the breaker every time i turn the switch off



#2 bathroom switches




    Code:

   

power feed line



line to the light over the medicine cabinet



line to the second switch to control the exhaust fan.

same issue as the first set, flip the switch and trip the breaker (different breaker from the kitchen switch)



#3 living room switch and plug controlled via switch




    Code:

   

 power feed line



outside porch light line



line to wall switch to control the lower wall outlet

flip switch, trip breaker



the switches i have are "1 pole" am i using the wrong switches for this job?
      

In a 1950s home the electrical is being redone. Wallboard was removed in the kitchen and there is a kitchen sink drain/vent line (seems to be 1" to 1-1/2" pipe) in the wall which is made of steel. It runs down into the concrete slab and up through the roof. There is an old electrical outlet (which will be removed and replaced) next to it which has a 14/2 cable and a separate small ground conductor running to it. With a meter I measure 50V between the steel pipe and the steel housing of the receptacle. Once the old receptacle is removed and a new one is installed, where and how will the drain pipe be grounded? I am sure there are more steel drain pipes used in this house but not all of them are open and exposed. Will it be sufficient to ground this one steel drain/vent line? If yes how and with what conductor size?
      

Live in California...  Pool and backyard remodel



Running a new 100Amp line from the main electrical house box that is 200amp to the new Hayward ProLogic Pool sub panel for the pool equipment. Is that #2 wire or #4?



The pool installers are telling me that they need 50 amps for the 3 pumps, 2 pool lights and gas heater that I have. 



The reason that I'm running 100amps to the sub panel and only using 50amps for the pool is because there is electrical going to the overhang and backyard that can be controlled by a remote that talks to the ProLogic sub panel.



I have a overhang/BBQ area that has 17Amps for the refer and BBQ, a water feature which is about 15-20 amps, 2 ceiling fans for the overhang, low-voltage lights for the overhang, low-voltage landscaping lights for the backyard only. I think that is about it.



Inspector is telling me that I need a GFCI at the sub panel. Is this a 100amp GFCI prior to the sub panel being wired? Or does each piece of equipment need a GFCI?



I am having a licensed electrical contractor do this, but I'm just trying to do my homework because some of them are not knowledgeable about pool wiring... 

(BTW, I had a licensed contractor out yesterday, to give me a bid and he said that they didn't make a 100amp GFCI, which of course I did see on the internet, not using him!!)
      

I'm getting ready to dig a trench to run electricity from my house to my garage.  Along with an electrical line, I would also like to run a line for my air compressor.  I would like to keep my compressor in my basement and have a line for it in the garage.  Does anyone have any tips for how to properly bury an air compressor hose?  I searched on Google a bit, but couldn't really find exactly what I was looking for.  Thanks.
