I'm relocating a 200 Amp service because of the back of a house getting bumped out. I've always been under the assumption that the ground wire has to be unslpliced from the main to the ground rod by the water main.
My question is... Is there any exception where you are allowed to splice the ground wire in order to extend it?
Thanks
(C) Continuous. Except as provided in 250.30(A)(5) and
(A)(6), 250.30(B)(1), and 250.68(C), grounding electrode
conductor(s) shall be installed in one continuous length
without a splice or joint. If necessary, splices or connections
shall be made as permitted in (1) through (4):
(1) Splicing of the wire-type grounding electrode conductor
shall be permitted only by irreversible compressiontype
connectors listed as grounding and bonding equipment
or by the exothermic welding process.
(2) Sections of busbars shall be permitted to be connected
together to form a grounding electrode conductor.
(3) Bolted, riveted, or welded connections of structural
metal frames of buildings or structures.
(4) Threaded, welded, brazed, soldered or bolted-flange
connections of metal water piping.
(3) Connections to an aluminum or copper busbar not less
than 6 mm ? 50 mm (1⁄4 in. ? 2 in.). The busbar shall be
securely fastened and shall be installed in an accessible
location. Connections shall be made by a listed connector
or by the exothermic welding process. If aluminum
busbars are used, the installation shall comply with
250.64(A).
