Bare copper grounding wire spider webbing in the attic.
First off let me introduce myself to the group. I just purchased my first home. It is in San Diego, Ca and it was built in 1962.
I opened up some of the outlets in the bedrooms and noticed that there is no grounding wire in the romex, just a hot and neutral. When going to the kitchen, I noticed that the boxes were metal and there was bare copper grounding wire connected to the box, not coming out of the romex it was a separate bare copper wire. Well I traced this wire up to the attic and found a spider web of bare copper wire. It seems as though certain boxes are grounded and others are not for example I believe the bathrooms and kitchen are but the bedrooms and living rooms are not.
The breaker box does not have a grounding box, it seems that all the grounding wires are going into the neutral bar.
So my first question is, if I wanted to ground some of the other outlets in the house can I simply run a bare ground copper wire up from the outlet to the attic and connect it to the spider web?
I will have many other questions although I am trying to read through the forums as much as possible to not repeat questions.
Thanks in advance.
