<br />1- ALL METALLIC RACEWAYS AND EQUIPMENT SHALL BE BONDED AND ELECTRICALLY
<br />CONTINUOUS (NEC 250.90, 250.96).
<br />2- GROUNDING BUSHINGS ARE REQUIRED AROUND PREPUNCHED CONCENTRIC
<br />KNOCKOUTS ON THE DC SIDE OF THE SYSTEM (NEC 250.97)
<br />3- THE GROUNDING ELECTRODE CONDUCTOR WILL BE CONTINUOUS, EXCEPT FOR
<br />SPLICES OR JOINTS AT BUSBARS WITHIN LISTED EQUIPMENT. (NEC 250.64)
<br />4- THE EQUIPMENT GROUNDING CONDUCTOR MAY BE USED AS A GROUNDING
<br />ELECTRODE CONDUCTOR. (NEC 250.121 EXCEPTION, INSTALLED PER 250.6(A), II, III, VI.)
<br />5- INSTALLER TO IDENTIFY THE EXISTING GROUNDING ELECTRODE TYPE (I.E. DRIVEN
<br />ROD, UFER, WATER PIPE, OR COMBINATION OF SOME
<br />OR ALL OF THE PREVIOUSLY MENTIONED). IN EXISTING ELECTRICAL SYSTEMS THAT USE
<br />ONLY A WATER PIPING GROUNDING ELECTRODE SYSTEM, AN ADDITIONAL GROUNDING
<br />ELECTRODE (I.E DRIVEN ROD) SHALL BE PROVIDED. (NEC 250.50)
<br />-PER NEC 250.53(2), A SINGLE ROD, PIPE OR PLATE ELECTRODE SHALL BE
<br />SUPPLEMENTED BY AN ADDITIONAL ELECTRODE OF TYPE SPECIFIED IN 250.52(A)(2)
<br />THROUGH (A)(8) SPACED NO LESS THAN 6FT APART.
<br />EXCEPTION, IF A SINGLE ROD, PIPE OR PLATE GROUNDING ELECTRODE HAS A
<br />RESISTANCE TO EARTH OF 25 OHMS OR LESS, THE SUPPLEMENTAL ELECTRODE SHALL
<br />NOT BE REQUIRED.
<br />-#4 AWG CU TO UNDERGROUND METAL WATER PIPE THAT IS A MINIMUM 10 FOOT BURIAL
