Low Voltage Wiring

I'm writing on behalf of my brother and sister-in-law; they purchased a house over a year ago and have yet to move in because of this electrical dilemma. Low voltage wiring, which the realtor and five electricians, told them would be no problem to work on... none of the electricians have returned after their initial visit. Although it's not a normal wiring system, it is pretty cool... they can monitor lights (on or off) from almost any room in the house. What's really delaying the move-in is the kitchen... they're afraid to install any appliances until an electrician sorts things out. I told them to just run all new wiring to the kitchen and wait until an electrician finally comits to figuring out and organizing the rest of the house. They both have the patience of Job, but a year... surely someone knows how to work on a low voltage wiring system. Their neighbor has the same type of system (I'm assuming the same contractor built their house) and loves it. Please if anyone has any guidance let me know. If anyone needs photos, I can have them take some... just wanted to see if anyone on This Old House could help first. Thank you... Rowland

Re: Low Voltage Wiring

Well, low voltage supply can affect the poor appliance performance, dim lighting and inconstant outages. As you said that you already had consulted five electricians and they have not returned after their initial visit, then I think, so you should call the professional and reliable one who can look out for the real source of electrical trouble and immediately start up the process with the most obvious solution.

I know this post is a little bit old, but I'm curious what you mean by low voltage wiring. Are you saying the home has 12v or 24v wiring installed? I've seen this before, but it's usually just for lighting circuits.

... or are you saying that the voltage coming into the home is low?

If it's the first issue, there should be separate circuits.

Eventually, they may just have to bite the bullet. There are plenty of good electrical shops that should be able to re-wire the kitchen. It's expensive... expect to pay around $5,500...

Re: Low Voltage Wiring

Probably too late for this poster but should someone stumble on this thread again (as I did), I suspect the house with "low voltage wiring" is actually referring to a low "control voltage".  Normal 120V power wires are run to fixtures that are to be switched and low voltage (e.g., 24V) wires are run from the low voltage switches to the fixtures.  Power is always available at the fixture and a relay at the fixture is operated by the switch to turn power off and on.
One site I found still sells parts for these systems.  GE was one of the manufacturers.
