| Your home most likely is wired without an equipment ground to each outlet box. Depends on the cable type. If non-metallic cable, the sheathing looks like black fabric, then this is only a 2 wire cable and does not have a ground at any of the outlets.
This can be corrected by installing a GFI breaker on each circuit, or a GFI receptacle at the first outlet on a circuit, or one in each outlet, whichever is best to cover the circuits.
If the cable is metal BX, then the sheathing is allowed to be an equipment ground. Each box should be grounded and you can install the 3 wire outlets with the jumper to the box.
The panel needs to be grounded properly no matter what issue exists for the outlets, and I agree with Strat the cost should not be too great to have this corrected.
As far as the home wiring, there are too many variables for any of to advice beyond what has been offered so far.
The work of re-wiring an older home is quite frankly, bull work. Not may electricians enjoy doing that type of work, esp when there is so much other easier work on going. Keep trying looking for contractors, but if the market is that busy where you live, I would be suspect of any contractor that takes this job.
Be sure to ask any contractor that does work for you for a written contract listing the exact scope of work, types of materials to be installed, how long the job will last, provide certificates of liability and worker comp insurances, do no give any money up front, and be sure there is a permit and the work is inspected.
Maybe too late for this school year, but you can try any vocational technical schools that offer electrical courses and see if they have classes go out into private homes to do wiring as on the job training. They cost will be greatly reduced, the work will be perfect, just one compromise, it may take a month of Sundays to get the job completed. |
