Installing A J-block

I'm using some lampholder fixtures for lighting in my garage and I'm wondering what to do with grounds?  There is nowhere to attach the ground wire to the box or fixture, so what do I do with it?  Neither the box or fixture is metal.  And what do I do with all the grounds in the switch box?
      

I just ordered some Arlington Siding Mount Kits with built in electrical boxes to install some lights on the outside of my garage. 



So, the issue is, the mount kits' built in electrical boxes are only 6.8 cu each and I'm wiring the lights up with two 3-way switches.  The source is at the first switch, then on to the two lights and then to the second switch.  There is not enough room to do the splices and connection in the built in boxes (I'm using 12awg, but even if used 14 still not enough room), so my plan was to wire everything to a central junction box inside the garage between the two lights and make the appropriate connections there. 



I'm attaching my rough sketch of the planned connections (omitting ground wires).  Can you guys please confirm this is correct?    Thanks for the help!



To clarify the drawing, blue is white (neutral) and the blue with black tape coming off second switch is marked as hot.  (I'll also mark it as hot in the J-box).  Yellow Triangles are wire-nuts.
      

I am installing a ceiling fan for my mom and the wiring has me a little confused. I posted pictures below of the ceiling fan wiring and the light fixture wiring. Just need to know how to connect the two together without burning down the place. Thanks in advance






      

I'm planning to use some round, 20 cu. in. ceiling mount boxes for lighting in my garage.  I want to run 12-2 into the box and then branch out out to two other seperate light boxes. 

Can I have 6 12 awg conductors and 3 12 awg grounds in a 20 cu. in. one box?
      

Hi All,



Need to replace an old faulty two switch fixture in the bathroom (light and exhaust fan). Right now, each switch on the single fixture separately operates either the light or the fan, regardless of the position of the other switch. Want to keep things that way. 



Here is a picture of the old fixture's wiring: http://dl.dropbox.com/u/1179096/photo1.jpg



To replace this fixture, I bought to the Leviton 5634 (design diagram he  http://communities.leviton.com/servl...224%205634.pdf)



Unfortunately, what is confusing me is the the different designs between the two fixtures and the fact that the original unit seems to have some kind of patch or cross over type wire connecting the top and the bottom switches (see photo link above).



Any help/advice on how to wire this new fixture based on the picture of the current wiring configuration would be greatly appreciated. Thank you!!!
      

Hello,



I am replacing a bath light and I am a bit confused by the wiring. I can reattach the wires with the new fixture exactly like the old fixuture was attached but the old fixture did not have a ground connection.



Here is how the wires a



Two whites connected to each other but not to the fixture.

One white and one bare copper wire (I thought it was the ground) connected together and to the white wire of the ligh fixture

one black wire connected to the black wire of the light fixture



How to I connect the the fixture green wire in this configuration?



Thanks
      

Hidy!

Hoping someone can guide me in the right direction. I have essentially no experience with electrical anything unless its a computer, and I am remodeling my Mother's guest room. We picked a pendant light to replace the old flushmount lighting. I've got the old one removed (and yes I have the power off in the room ), and I cannot figure out how to do this based on the instructions given (or on any video I have watched).



There are two copper "wires" coming down from the ceiling. They are both wrapped in black insulation, and they form like a little hoop/circle on the end. The fixture has a copper wire, not insulated, and like a double copper wire insulated with brownish black coating. Sorry...I don't know technical terms here, but I would be happy to post pics.



I just need help installing this thing. I've done flooring and plumbing and everything else you can imagine a chcik might figure out how to do, but I am stumped here. Please help me do this! It doesn't seem like it should be this difficult!
      

With a hard wired LED closet light fixture, can it be wired like an undercabinet fixture? clamp the wire to the light and push the excess wire into the ceiling?

 

Or can i install an outlet on the ceiling and use the plug in style lights?

 

Im going to install a switch outside of the closet so there will be 1 wire going to the light.



What is the best way to do this?
      

Greetings!

I'm hoping for some help, I bought a house recently where the laundry room light switch does not work. I found this in the ceiling box:



Two black wires capped off

One white wire capped off

Three white wires going to the fixture

Two black wires going to the fixture



I replaces the switch to rule that out and it still doesn't work.



There is one black and one white wire going to the switch.



Any ideas on how to wire it properly?



Thanks!
      

I have an outdoor light fixture that I am trying to replace.  The house was built ten years ago.



When I removed the original lamp, I noticed one of the two leads was wired to the ground, and one was wired to the black wire, which is hot per my current sensor.  There are three wires in the box - black, ground (bare copper), and white or neutral, all from a single romex cable.  Unfortunately, I do not recall where the white was when I removed the original. 



I wired the new lamp per the instructions, something I have done many times before - black to black, white to white, and bare copper ground to ground.  Nothing.  The lamp and bulbs are brand new, and I have tried four separate bulbs.  I checked the black and neutral with my current sensor and with the switch on and the lamp installed this way, both show as hot. With the lamp not installed, the switch on, and the wires disconnected only the black shows as hot.  The switch is single pole, and appears to be wired correctly with a black to each screw on one side and a copper ground on the other.



Assuming the new fixture was bad, I reinstalled the old fixture correctly -  black to black, white to white, and bare copper ground to ground.  Still nothing. No light, and I confirmed the bulb is good by putting it in another lamp.   The only way to get it to light is to connect the neutral in the lamp to the bare copper ground.



I capped the wires, turned the circuit back on, and identified all the outlets, switches and fixtures on the same circuit.  I opened every one of them up (four lights and eight outlets) and found three (one switch and two fixtures in another room) where multiple commons connect.  All were properly connected.  My outlet tester shows all outlets as "correct".  I found no instances of grounds connected to commons or vice-versa.



Any ideas?  Is it proper to wire this thing the way I found it?



Thanks for any and all advice!
