Underground ground rod connection issue
My power to a detached garage (3 phase) has its ground rod buried in the concrete outside the door. No visable wires so I can only presume it runs under ground and into the service panel. What can I do to get my star ground connected to the rods? Can I simPly patch it into the earth wire at the back of the panel ? Thanks

I forgot to add, I ask this as there is no ground buss bar in my service panel.

The ground rod into Mother Earth is there for safety from thunder & lighting storms or if the power company has a real big problem. The green safety ground wires (EGC or PE) should be connected near the breaker panel at the building service entrance.

Now that I don't know! I'm some 12 000 miles away so I just can't pop in. There are many different ways to wire a three phase system. How are the other circuits connected to Mother Earth?

recommend you get a licensed electrician to look at this. not having a ground in the service main is likely a serious issue. and you should only have a single earth ground (unless you have it engineered for another purpose - which it sounds like you do not).
