We wired up a couple of modulars here in jersey, they were built in pennsy. These guys left out just about all the travelers for all the three ways in the house, it was soooo much fun trying to install them after the house was put together. And to make it more fun no one had the foresight to see where the utility power was, so the panel was in the garage and the pole was on the other side of the house, so we had to put a disco outside, make the main panel a sub, and do all this with the place sheetrocked. Modulars are just great. lol
That sounds typical.
There are numerous manufactured home plants in PA. The plant would not know where the Utility power was going to be. Each unit of a particular model would have the panel in the same location.
George,
My guess is that they figured it to be cheaper in materials and time, and not all homes are wired using these devices.
For example, in the Marlette plant, they had different levels of homes, and different brands of homes. (I don't know if they still do, but I could check)
The cheaper model of home usually had the Slater devices. they take a special crimp tool to install them.
It is the box and device. no wire nuts needed.
If you look at how mobiles are constructed, you would see a big difference in how single family dwellings are wired.
There are different types of electricians in the plant, each with a specific job. Bottom Electricians, side wall electricians, ceiling electricians, device electricians, service electricians, and others. Some do multi tasks, others not.
The bottom electricians will pull wires that will be on the 'bottom' of the home. They mainly pull jumpers, homeruns, and maybe hook up a receptacle for heat tape, and install a junction boxes or the TYCO devices for connections.
The walls are built in different locations. Then brought over and installed into the home. Many walls might show up with the holes pre-cut where the device is going to be. The wall electricians bring the jumpers from the bottom up to a switch or device hole and poke it through. They pull the jumpers that go around most walls.
The ceiling electricians pull all of the lightin jumpers, and so on.
The guy trimming out inside the home, basically goes from hole to hole installing devices, all the wires are there for him.
