Recessed Lights / Box Volume Size

wanted to get feeback on my crude wiring diagram i put together for my small bathroom remodel. does it appear to be sound or am i way off base??



details:



* 20A dedicated circuit

* 12/2 wiring

* outlet's will be GFCI

* double gang box will contain:

* timer unit for exhaust fan

* double switch for heat lamp and lights

* Ground wiring is not shown but each fixture/outlet/switch will be connected to ground wire

* by calculations, the 34cu box is fine for the number of conductors/size of wiring. per box specs could handle 15/12g wires.

* the scanner cut off the bottom part of the picture, the 2 lights on the right are fed from the same switch, neutral's connected together.



F = Exhaust Fan

L = Light

HL = Heat Lamp

T = Timer switch

S = Switch

H = Hot

N = Neutral

Wire Nuts are in the box connecting the pigtails



Thank you for your input.
      

I NEED TO UPDATE MY ELECTRICAL PANEL. I FIND THAT SOME OF MY NEUTRAL AND GROUND  AND HOT WIRES ARE A BIT SHORT OF REACHING THE GROUNDING  BAR AND FOR THE BREAKERS. HOW DO I EXTEND THESE WIRES? CAN I ADD PIG TAILS TO EACH WIRE, USING WIRE NUTS?



Thanks in advance for any help or reply
      

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 planning on installing recessed lights in my basement.  The ceiling is currently unfinished, so I have complete access to it.  Would you suggest I use 5" or 6" lights?  Also, I have attached a picture of dimensions and the small circles are where I have the lights going.  Using a total of 15 lights in 3 rows.  Is this too many lights?  Is the spacing correct?
      

Can you install 6 recessed light off of one circuit by starting at a switch that is designed to turn an outlet on and off for a lamp that sits on a table.  i've determined all of the outlets in one room are on the same circuit.  The max wattage that will be used in that room if all recessed lights and TV etc are on would be approx. 1,500.  the electrical wire in place is 14 g.
      

4 gang switch box. power into this box. All wire is 12 Guage.



Neutrals and hots are easy to nut together, 5 at most in 1 nut.



But what about the ground wires? There will be 9 total ends that need to be connected, 9 seems like alot under 1 wire nut.....or is it? lol



Can i make up 2 sets of grounds and use a jumper between the 2 wire nuts?



Do they make a wire nut for 6 wires?
      

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!
      

Finishing basement and have a few questions...



1. Have already bought recessed cans. Commercial Electric brand. I have now read a few places that these are junk. Why exactly and should I return them? Need to know know before I paint them black.



2. I plan on installing 12 lights on new 15A circuit using 2 switches one for left side of basement one for right (6 x 6). This is OK yes? Both switches will be in same box. And will be only thing on this new circuit.



3. Assuming I am running hot lead from main panel to switch box...there is no fancy wiring that needs to be done correct? 14/2 black to black, white to white except at switch correct?
      

1) Is it required by code to wrap all wire nuts with tape?

2) Is it ok to run 14/3 wire to a lighting fixture that is on a 20amp circuit, for a 3 way switch? The wire goes no further than the second switch (doesn't feed anything beyond it of course), and of course 12/2 is feeding the first switch.



Thanks.
      

I am redoing my basement, and i am making the electrical runs for the recessed lights in the ceiling. I am using 14 gauge wire, and i have 16 recessed lights with 65 watt bulbs in them, however they are rated at 75 watts max. assuming someone after us may put in the max bulb, the total watts would be 1200, equaling 10 amps. When all of the new wiring is done, i am going to have an electrician connect the circuits to the circuit breaker (using 15 amp breakers) however since i am not comfortable doing this myself, and i would like to use the lights now, can i connect them to the existing 12 gauge wire (this will not overload the breaker... i already checked what else was plugged in to the electrical outlets).



to recap:

The power draw will only be 10 amps at MAX. capacity

existing wiring is 12 gauge/ 20 amp breaker

electrician WILL connect 14 gauge wire to breaker using 15 amp breaker



*THIS WILL BE TEMPORARY*
