| | |
| | 1) NOTE: PLEASE SEE RISER HAS NOW HAD CONDUCTORS AND |
| | CONDUIT REVISED WHICH HAS SEVERAL CODE ISSUESWHICH |
| | NEED TO BE ADDRESSED. |
| | |
| | A) AS REDLINED AND STATED ON ALL PREVIOUS REVIEWS: *AN |
| | EQUIPMENT GROUNDING CONDUCTOR SHALL NOT BE INSTALLED |
| | BEFORE THE FIRST MEANS OF DISCONNECT. PLEASE SEE 250.24 |
| | AND 250.6. AS THE CODE REQUIRES THE GROUNDED (NEUTRAL) |
| | TO BE BONDED AT THE FIRST MEANS OF DISCONNECT, IF AN |
| | EQUIPMENT GROUNDING CONDUCTOR IS INSTALLED FROM THE |
| | METER TO THAT FIRST MEANS THIS WOULD PARALLEL THE |
| | NEUTRAL AND CREATE OBJECTIONABLE CURRENTS WHICH IS |
| | SPECIFICALLY STATED IN THE SECTIONS ABOVE. |
| | |
| | B) PLEASE SEE THE HOT/PHASE CONDUCTORS HAVE NOW BEEN |
| | DOWN SIZED TO 3/0 CONDUCTORS AND STATES PER 310.15B. |
| | PLEASE SEE THAT THE SECTION NOTED IS INCORRECT. THE |
| | SECTION IS 310.15(B)(6)AND IS STRICTLY FOR |
| | *RESIDENTIAL* AND NOT FOR COMMERCIAL USE. |
| | THE MINIMUM HOT/PHASE CONDUCTORS FOR THE 225AMP MAINS |
| | IN A COMMERCIAL USE PER 310.16 IS 4/0. THIS WAS ON |
| | ORIGINAL RISER. |
| | |
| | C) PLEASE SEE NOW THE CONDUIT SIZE HAS ALSO BEEN |
| | DECREASED. PLEASE KNOW AS NOTED IN SECTION B) ABOVE THE |
| | CONDUCTORS ARE REQUIRED TO BE 4/0. IF YOU FIGURE THE |
| | SIZING PER TABLES IN CHAPTER 9, EVEN USING PVC SCHEDULE |
| | 40, OR EMT THE 2INCH CONDUIT IS NOT LARGE ENOUGH FOR |
| | THE CONDUCTORS. |
| | PLEASE SEE CONDUIT FILL NEEDS TO BE ADDRESSED EVEN IF |
| | #4 EQUIPMENT GROUNDING CONDUCTOR AFTER THE FIRST MEANS |
| | OF DISCONNECT IS USED. |
| | THE 2 ? INCH CONDUIT ON ORIGINAL RISER WAS CORRECT FOR |
| | THE CONDUCTORS WHICH WERE SHOWN ON ORIGINAL RISER. |
| | THE 2INCH CONDUIT BEFORE THE MAINS ARE OK FOR 4-4/0. |
| | |
| | D) PLEASE SEE A CODE SECTION OF 250.66 IS REFLECTED ON |
| | RISER FOR EQUIPMENT GROUNDS HOWEVER EQUIPMENT GROUNDING |
| | CONDUCTORS ARE SIZED FROM 250.122. |
| | PLEASE ALSO SEE THE RISER SHOWS 3 #4 EQUIPMENT |
| | GROUNDING CONDUCTORS PER CONDUIT?? PLEASE SEE 250.122 |
| | AS ONLY ONE EQUIPMENT GROUNDING CONDUCTOR #4 IS |
| | REQUIRED FOR UP TO 300AMPS. |
| | |
