I just bought my first house and I noticed that in the kitchen there are three outlets, all installed with GFCI outlets. The house is not grounded, and has 2 prong outlets everywhere else in the house. I was under the impression that you only needed one GFCI per circuit. If you put one at the beginning of the chain, then it covers all of the outlets farther down in the chain. If thats the case, then I'd like to pull out the 2 extra outlets and move them to other parts of the house (just to save money on buying GFCIs for the rest of the house) and replace them with 3 prong outlets. I'm going to slowly work on rewiring the house with grounded outlets, but figured this would be good in the meanwhile. Am I seeing this right? I know theres some requirement that plugs within a certain distance of a water source need GFCI, but do all of them?
