I will contact the concrete guy and see if he left a connection but I doubt he did. You are going to like this, I was just told that I have to run a #4 copper ground wire 20 ft to the rebar that is in the footing of the addition we just put on. I spoke with three electricians up here and all of them told me to get grounds. What is worse if I would not have told the guy we put footings in then I would not be required to use them. Contractors are not required to install rebar in the footings. I have no idea what I am going to do and I will have a 20-30 ft copper ground wire running through my home, down the wall and in to the footing. You may want to add that bit of info to the website.
Hi Eric - I'm assuming that with your addition there was an electrical panel installed, or an upgrade, which would have caused the inspector to investigate the need for the bonded ground. I can't help but have a few questions, yet I am not totally aware of the details of your project. Typically the approved plan set will indicate which type of ground should be installed for a new home, and it is typically a ufer ground consisting of a 20 foot #2 rebar that is tied to the bottom bundle of rebar and the end would be above the foundation below the panel location, or for a 200 amp panel a #4 solid bare copper wire installed into the foundation which is tied to the bottom bundle of rebar which is 20 feet inside the foundation and then extra length would be leading out of the foundation and up to the panel location. At the jobsite, the electrician usually makes sure that this is installed before the foundation is poured and is verified by the inspector. I can provide more about grounding, but first I would like to know more about your project.
