I believe that you can run a bonding jumper, sized in accordance with 250.66 (#4), to the GEC from the UFER ground. Connection has to be made using a listed means- I would use a correctly sized split bolt lug.

Perhaps the inspector would care to comment on this?

Re-use a service entrance cable and grounding requirements


Well, I did the upgrade on Friday. Thanks to everyone that responded to this post - it went pretty well for my first time. For any other newbies reading this in the future, here are some of the things I learned/recommend in addition to all else in this thread:

1) For underground service pay for the disconnect. I'm sure it could've been done live but I'm glad I didn't have to worry about dying!
2) For how thick it is, 200 amp SEU cable is not that expensive relative to other cable. I reused some cable that I had (it was in good shape) thinking it would save me a lot of $ but when I saw the l.f. cost at the store it really didn't.
3) the 200amp SEU cable is hard to bend and work with. Plan your route carefully and expect to fight with it if you have some relatively tight angles it needs to follow.
4) make sure you have enough length of cable to allow the internal ground wire to reach the grounding lug. I almost screwed myself with this one thinking it only had to reach the main service panel lugs and the main ground lug was another 5 inches lower.
5) It took me 5 hrs after pulling the meter to do the following:
*remount the meter pan over the new siding,
*remove the exsting 100amp service cable,
*drill the hole bigger for the thicker 200amp service cable,
*remove the 100amp service panel (disconnect 12 breakers),
*move into place the new 200 amp service panel, increase the holes and *install 2" cable locks on the meter pan and service panel,
*run the 200amp service wire to the service panel,
*install the wire into the meter pan and service panel, and finally
*install the ufer ground wire into new service panel

I drove the copper rods into the ground before they disconnected the panel and these went into the ground much easier and faster than I expected (about 15 min for both). I still need to hook up the ground wire to the rods and the water line plus install about 14 circuits in the new panel.

I was in such a hurry I didn't take the time to grab pics. You gotta love the electric co. They show up at 9am with two big bucket trucks and a service truck, tell me to call them when I'm done anytime before 3pm but show up at 12:30pm anyway and the whole crew just sits there waiting until I finished. efficient as a gov't agency. The crew really was super nice, though.

Typical M.O. for a line crew, and people wonder why electricity costs so much?
