Does anyone know anything about Integrity Building Systems, as far as the electrical end of it goes. I am looking at plans for a 3 story townhouse (row). I need to know what to expect, so that I can give a number.

It sure looks like quality, from the appearance of the web site. I also am very interested in this type of construction.

I watched one being built (from a distance) in my neighborhood. 6" walls insulated with what looked to be styrofoam. I think all the outlets and fixture boxes are prefabed with the walls and ceilings at the factory.
I have always wondered how they connected the electrical in the field. Is it NM, conduit or what. I know one thing for sure. It is the best insulated house I have ever seen. I wish I knew more about it......John

I heard about it but for wireing i think someone did told me they still used the NM romex wires.

for connectors tell you the truth i dont think it is not any worst than the prefab run of mill homes is but i may be wrong on that part.

the last prefabbed home i did work on it have " speed " connectors IMO myself i dont like that speed connectors at all for that one i allready found 2 failed connectors.

but please do keep us posted with the new type of construstion i am like to know more when you deal with that and see what is your feedback on that one.

Merci. Marc

My question again is how do they connect the sections electrically. Do they put a box between the sections or do they have specially designed connectors, fittings ect.....

It's common in the industry to use "molex" or "Amp" connectors on the crossover wiring. They are approved for concealed use without access.

I see. thanks.....John

Important point - The ones I have done are "roughed" backwards. Electric, plumbing, HVAC. THIS IS VERY IMPORTANT!! You will need to drop feeds down a chase to the basement to run to the panel. The HVAC also will go into this chase, so if he gets in 1st, you are out of luck, big time. At least, this was my experience.

The ones I did recently (2006) were delivered to the site in 6 different sections: 2nd floor front, first floor front, first floor middle 2nd floor middle, first floor rear, 2nd floor rear. Each section had tails dropped down a chase to the foundation and were either run back to the panel as homeruns or needed to be spliced with other lines from the other sections, like smoke detectors and 3-ways. My experience was unpleasent because the original installers made alot of mistake in their wiring and in their labeling of the circuits to the basement. Without a tone generator I would have been lost.

The ones I have done had all SUPPOSEDLY been energized and checked out at the factory. BS!

I never had one where I didn't have multiple troubleshooting issues. (I've probably done 20-25 or so)

Did yours also have conductors about 2" long coming out of outlets boxes?

How about the splices - worse you've ever seen?
