Note: All automatic transfer switches shall be of the open-transition (break before make) design. This must be indicated on the information provided. Jf electronic starting or other significant harmonic producing equipment is to be installed, a harmonic profile of the load at each harmonic up to the 50th multiple, is required. Equipment must meet IEEE 519 standard for harmonic generation.

SERVICE MODIFICATION OR UPGRADE

Please provide the following information for an existing service:

Electric Service Request Form: If modification pages 2 and 3; upgrade pages 2 and 3 - list added load only.

Drawings: One (1) set of drawings which reflect any remodeling to be performed (if applicable). Ifpossible, please submit on disk (AutoCAD) to expedite the design process.

Riser Diagram: See above description. Both the existing and new service arrangements shall be shown.

Manufacturer Info: See above description.

2. DOORS SHALL NOT LOCK FROM THE INSIDE. DOORS SHALL HAVE INSIDE PUSH BAR (PANIC BAR) AND SWING OUTWARD. DOORS SHALL BE IDENTIFIED AS "ELECTRICAL ROOM" OR "METER ROOM". BOTH DOORS SHALL BE LOUVERED, UNLESS ROOM IS CLIMATE CONTROLLED WITH HVAC SYSTEM. SMECO SHALL BE PROVIDED ENTRY ACCESS TO ROOM AT ALL TIMES. ONCE METERS ARE ENERGIZED, CONTRACTOR /OWNER TO PROVIDE SMECO WITH TWO KEYS, FOR EACH ROOM ON SITE, AND ALLOW FOR SMECO TO INSTALL A LOCK BOX AT TOP OF THE DOOR OR ON THE DOOR HANDLE. IF DOOR IS EQUIPPED WITH A DIGITAL LOCK, SMECO IS TO BE GIVEN THE PASS CODE/CARD. ANY CHANGES IN THE LOCKING SYSTEM, (KEY, CODE OR CARD), IT IS THE RESPONSIBILITY OF THE CONTRACTOR/OWNER TO PROVIDE SMECO WITH CURRENT KEYS, CODES OR CARDS.

3. AT ALL TIMES, A MINIMUM OF 4', MEASURED FROM THE FRONT OF ALL PANELS, TROUGHS, JUNCTION BOXES, CT CABINETS, METER BASES, SELF CONTAINED AND GANG STACKS, AND SWITCHGEAR, SHALL REMAIN FREE AND CLEAR OF ALL OBSTRUCTIONS. ROOM rs NOT TO BE USED AS A STORAGE AREA. NEC SECTION 110.26

NESC SECTION 125

4. METER ROOM PLANS MUST BE SUBMITTED TO SMECO FOR APPROVAL. THIS APPROVAL IS IN ADDITION TO NEC AND/OR LOCAL GOVERNING AGENCY REQUIREMENTS. PLANS ARE TO SHOW THE LAYOUT AND DIMENSIONS OF ALL PROPOSED SERVICE EQUIPMENT AND MUST BE APPROVED BY SMECO PRIOR TO INSTALLATION.

5. ALL METERING AND SERVICE EQUIPMENT MUST BE PERMANENTLY MOUNTED AND LABELED TO PROPERLY IDENTIFY THE RESPECTIVE ADDRESS, SUITE OR UNIT. ADHESIVE TAPE IS NOT TO BE USED FOR IDENTIFICATION PURPOSES. IT IS THE RESPONSIBILITY OF THE CONTRACTOR/OWNER TO NOTIFY SMECO OF ANY ADDRESS CHANGES,

6. ALL METERING AND SERVICE EQUIPMENT MUST COMPLY WITH ALL SMECO STANDARDS AND SPECIFICATIONS.

7. A ROOM HOUSING A SINGLE SERVICE SWITCHGEAR IS NOT CONSIDERED A METER ROOM. THEREFORE, THE METER BASE ASSOCIATED WITH THE CT COMPARTMENT SHALL BE MOUNTED ON EXTERIOR OF THE BUILDING, A MAXIMUM DISTANCE OF 50 WIRE FEET FROM THE CT COMPARTMENT, AND NOT WITHIN THE SWITCHGEAR ROOM. FOR EXPECTED DEMANDS ABOVE 500KW, AS CALCULATED BY SMECO, CONTRACTOR/OWNER IS REQUIRED TO HAVE A DEDICATED TELEPHONE LINE AVAILABLE FOR SMECO'S USE AS A COMMUNICATIONS MEDIUM FOR METER READING. IT IS THE CONTRACTOR/OWNER'S RESPONSIBILITY TO PROVIDE A DEDICATED wDIAL TONE" PHONE LINE AT THE METERING LOCATION.
