Replacing (very) Old Garage Door Opener--is It 250v?

Ones anyone have any ideas on how to override the electronic eye system on a craftsman garage door opener. I want to use one for a trolley to access the back of my loft. Have no way of setting it up with the eyes and I also don't have an extra set of eyes
      

Scratching my head on this. New pole building. For now, I want to use one circuit for the lights. What I'm trying to do, is, at one door, I have a 3 way, switching two flourescent lights. Also in that 4-gang light switch, is run a light over the door on the outside, and a light over the overhead service door, and another light over the door, on the inside. So 1 3way, and three single pole switches. At the back door, the other 3 way for the same two lights, and a light over the door on the outside, and another light over the door on the inside. I have the power from the m/p, going into the light box nearest the M/P. Long story short, instead of how I have it, which operates all the lights, as long as one of the three ways are on. If someone could help me with how it should be. I am using 12-3 from the switches. Using 12-2 from the first light box, to the second. I have a another 12-2 running into each switch box, to supply power for the single pole switches.

Thanks for any/all input.
      

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 some help connecting a programmable electronic timer switch to an electronic door lock.  My goal is for the door to only unlock during a set period of time (when the timer is in the "on" position).



I have found two locks that I think may work, I just have no idea what wires to connect to what.



I attached three pictures.  Two of them are of the electronic timer (two different versions), and one is of the locking mechanism. 



Any help is greatly appreciated.
      

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?
      

OK, here is my problem.  I live in a newly constructed house.  They are building a new house right next door.  I am seeing a power flux (dimming) in my lights whenever any of the following occurs:



- I turn on the A/C in my house

- I turn on the washing machine in my house

- the compressor next door kicks on (for their nail gun and/or other tools)



The compressor next door is hooked up to a temporary post on the street.  I have had my electrician come look along with the utility company.  The utility company says that the house is getting plenty of power.  So now, short of getting another electrician in here, trying to figure out what the problem could be (and if my electrician, who is the one who did the wiring during construction, doesn't know what he's doing).  Most of the lights in the house are 60W if that matters.



Any thoughts on what the problem might be?  I would think that given the proper wiring that I shouldn't see any kind of power flux.



Thanks for the help in advance.
      

I admit, I'm jealous of the European style light switches, with the little white buttons instead of the standard switches they have here in Canada. I don't know much about the design of the European wall switches, other than they are designed for 250v 10a systems. And that I can buy them on eBay! So I am wondering if anyone can tell me whether it might be possible for me to install the European 250v light switches on a North American 120v system?
      

i am rewiring a bedroom. the wall with the window is 10'ish. on the right side of the window = between window and corner, will be an outlet.

the left side of the window. there is a closet door, on the left wall,  that opens to be  flush with the window wall. so no furniture can be put there. should i put an outlet there anyway ?
      

Hi

I  have a light circuit 15 amp 14gauge(7  cfl lights) ,and am going to link off of it 15ft to garage(is the only wiring close).will be putting 3 plugs,1st  -GFI; and 2 cfl lights on the line.I dont plan to use any appliances /compressors,etc. Will have garage door opener1/3 hp ,and may use vaccuum ,or 13 amp  saw once in a while,but not often

Do you see any problems with the set up ?



Will i be able to run the 13amp 60 hz (4500rpm no load ) saw,ok ,or small vac,even if lights are all on? I wont use the plugs together at same time even though there are only 3 on entire circuit.

Any info is appreciated.
      

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!
