how do you ground a house (I'm in peru)?

Question

I'm getting low grade electric shocks from my appliances, and the electricians who are quoting prices are sky-high. I didn't think grounding a house was such a big deal.

Answer 1

Do the wires in your wall have three strands, or two? If the electrician has to run all new wire, it would explain the high estimates. If this is the case, I would hire the electrician, unless you are planing on gutting the entire house of dry wall / plaster. The electrician can snake the wire without gutting.

Answer 2

I wonder if you are at high altitude, or in an area with low relative humidity. If so, perhaps the shocks you feel are not from the electrical wiring, but static electricity. If it is static electricity, you should feel it also from any metallic object, not just appliances.

If it is from the electrical wiring you should read an AC voltage between a water pipe and a bare metal part of the appliance.

Answer 3

I would suggest you get another estimate. I wouldn't recommend you mess with your grounding system.
Good luck.
