How do you ground your home electricity to your box?

Question

I have old k**b and tube wiring this is why I ask?

Answer 1

wood werk is right you dont have a ground wire in your house you'll also have to run a ground wire throughout your house

Answer 2

You would have to run a bare ground wire

parallel to each k**b & tube circuit.

That k**b & tube work was probably installed

about 1930.

The old rubber insulation will have become brittle.

It's time to think about replacing it.

Answer 3

This would be done by driving an 8 foot ground rod into the ground and attach a #4 bare copper to the rod and also to the metal ground bar in the panel.

Answer 4

yes, per fireman4, that is how you run a ground wire from your panel box to a grounding rod. but, with k&t wiring, none of your outlets are grounded. you might want to look into upgrading the wiring.

Hope that helps.

Answer 5

Home electricity is too dangerous for an unqualified person to be giving advice. The potential for personal injury or death, and for a fire are too high. You have too many of that kind of answer already and that is scary.

First, what are you really asking? I have a feeling that you are using actual terms but ones that are not correct for what you really want to know and the previous answerers didn't realize it. Second, why are you asking it? What is your goal?

We need to know that in order to tailor the answer to what you need. One thing that I can say with absolute certainly. Since you are asking this the way you did and the fact that it is here, you don't know enough about the subject to do this safely. In any case, you can learn the terms and the rules here, but you can't learn the practical aspect of it from reading.

Among other things, the previous answers seem to ignore the fact that one side of the line coming into your house, the neutral line, is already grounded by the power company. NEC does specify additional grounding at the service entrance because the redundancy adds to the safety.

The fact that you know the term "k**b and tube" is a plus, but I still fear you know too little about it to work with it safely.

By the way, it is not always safe to ground to a water line. You need to know some things before you do that. Also the steel lines are not cast iron. There may be cast iron on the drain lines, but you are not supposed to ground to drain lines.

By the way, do you have a ground rod already? It may be on an external meter hub. Is your meter outside or inside?

P.S. DT, are you still there? Any answers to those questions about your post?

Answer 6

I have been told that in a pinch you can ground to any cast iron or copper pipe (cold water supply) in your home, as long as it extends at least 10 feet into the ground.
