When GFCIs were first coming out in the NEC codes, was it common to see them at first? I ask, because my house was built between 1976-78 and surprisingly, there are no GFCI outlets or breakers anywhere. I suppose that the new code just wasn't accepted yet, but a relative's house in the same county built in 1978 has GFCI breakers for the baths and outside outlets.

Another thing I have noticed is my home has one 20 A circuit for kitchen lighting and counter outlets. Same with the bathroom. Shouldn't there be two 20 A circuits for each of these rooms?

I've also noticed that the outlets in some room are on the same circuit as those in other rooms. Example, the washing machine circuit also has a hallway outlet and 3 outlets in the adjacent bedroom on it. This is annoying when trying to vacuum and run the washer at once.

My house was built by a contractor for himself so I don't understand these things being overlooked.
