Installing Switch From Hose To Attached Garage

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.

Does standard drywall have 15 min. finish rating or is this identified as the "fire resistant" drywall.  And does a detached residential garage even require a 15 min. finish when nm is used?  I have read and read and it seems as though exposed nm is acceptable in an attached garage but not in a detached garage???  I still can't seem to wrap my head around the logic of some of the NEC codes....
      

Hi everyone, this is my first post.  Hope it works out!



I have a new detached two car garage with two 115v 15A circuits in it.  I want to put in a 12000 BTU window air conditioner.  One circuit runs 10 fluoresent bulbs in the garage and a few in the house but also runs a few outlets in the house that see occasional use by a 12A vacuum cleaner.  The other is solely used for the door opener and outlets in the garage where I often use a 12 amp skill saw. 



Both circuits are aqccessible, which one should I choose?

hi i need a power supply to my garage/workshop, i have a spare in my consumer unit in my house type b 32a mcb, and will i need a 4mil swa?? or 6mil swa?? from the cu in the house to the garage cu,(63A. 30MA. RCD., 1 x 6A lights + 1 X 16A scokets. MCB),, i will be useing a welder, grinders with a(240v- 110v transformer) and there will be 2 double scoket outlets in the workshop,,,is this all correct?? thanks,
      

I had a tv plugged into an outlet in my garage. The tv crapped out due to bad wiring {I think}. The reason I say bad wiring is because when I have a radio plugged in I can hear static through the speakers due to the wiring. Garage was built in the 70's. What do I look for when checking the wiring from the house to the garage and then all the garage wiring itself?
      

I built a free standing garage with main power tapped from the home breaker box.  The contractor pulled 4 wires via a conduit to the freestanding garage panel which supplies lights, a garage door, and two 20 amp outlets.



Everything worked well initially, but about 1 week ago one section of the lights in the building went out.  The contractor came out and found that one of the two hot wires in the garage panel was only seeing 100 volts and that went down if anything else was turned on.  He swapped one of the ground wires for the bad hot wire and everything now works. 



What would cause a situation like this where the hot wire apparently had a voltage loss?  Is it safe to continue with the fix where the faulty wire is now the ground?



Thanks in advance!
      

I want to set up a hobby woodworking shop in my garage. I was going to run from the panel maybe four or five 12/2's to accommodate lighting, power tools, dust collection, etc. or should I put a subpanel 60 to 100 amp? The main panel is on an outside wall on one side of the house and the garage is on the opposite side of the house. The distance from the panel to the entry into the garage is about 50 ft. I would be pulling wire- a straight run- through a ceiling chase that runs the length of the house. No basement.
      

i want to add a sub panel to my detached garage 30 ft from my house.it will need to run a 220 compressor 2 to 3 outlets and a 5 person hot tub behind the garage.what size sub panel would i need to do the job?
      

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.
      

Hi,



I would like to wire a switch to be able to cut the power to the ceiling mounted outlets that feed our garage door openers. Running new wiring to them will be a bit cumbersome, so I am hoping to avoid that. The ceiling outlets are powered by light fixtures in the garage (one near by each outlet). There is a 3 wire romex cable running from the light switch to the first light and another one between the lights, and then regular 2 wire romex cables from the light fixtures to the outlets. The red wires in the 3 wire cables to the lights are switchable, the black wires are always hot.



I mainly want to be able to cut the power to the doors when we are away on vacation, and the reason for that is that one night both doors somehow opened up - I have no idea why. I'd hate for that to happen when we're away. Unplugging and plugging in the openers is a bit of a hassle due to the high ceiling.



I thought about wiring in a switched outlet so that I could just reach up with a long handle of some sort and switch off the power to the outlet. It would not be ideal, but definitely easier than getting the ladder out and unplugging the door openers.  However, there is possibly another option that I'd like some input on if anyone cares to comment. I believe I could wire in a switch on the wall next to the light switch that would allow me to cut the power to the black wires in the 3 wire cables. This would cut the power to the ceiling outlets and anything downstream from there (possibly an outside light, I would need to check on that).



My question is, are there any potential issues with this sort of wiring? Is there perhaps any code violation if both hot wires in a 3 wire cable can be switched off separately?



Thoughts?
