IMPORTANT POWER NOTES WIRING NOTES INCOMING WIRE SIZE NOTES ( CONTRACTOR FURNISHED -CONTRACTOR INSTALLED) ( CONTRACTOR FURNISHED -CONTRACTOR INSTALLED) 1. POWER LINES FOR EQUIPMENT LISTED SHALL BE DEDICATED LINES RUN DIRECTLY FROM NEAREST FACILITY POWER SOURCE. UNDER NO CIRCUMSTANCES SHALL ANY OTHER ELECTRICAL EQUIPMENT BE CONNECTED TO THESE POWER LINES NOW OR IN THE FUTURE. LINE REQUIREMENTS A. NO TRANSIENTS (IMPULSES FROM 0.5 TO 800 MICROSECONDS) THAT EXCEED 30F NOMINAL PEAK LINE VOLTAGE, AS MEASURED BY A POWER LINE ANALYZER, WITH THE SYSTEM IN STANDBY SHALL OCCUR. B. TRANSIENTS EQUAL TO OR GREATER THAN 30F NOMINAL PEAK LINE VOLTAGE. - SHALL NOT OCCUR MORE THAN ONCE PER HOUR. - SHALL NOT EXCEED MORE THAN 12 IMPULSES PER 24-HOUR PERIOD. 2. IF ANY OF THE ABOVE POWER SPECIFICATIONS REGARDING LINE TRANSIENTS OR NOMINAL LINE VOLTAGE, CANNOT BE MET, THE FOLLOWING CORRECTIVE ACTION MUST BE TAKEN: CONTACT TOM FISHLER, P.E. 262-827-9101 TEAL MEDICAL CORP. TO ORDER AN EQUIPMENT SPECIFIC TEAL UNIT. WHEN PLACING ORDERS: REFERENCE FILE NAME LOCATED IN BOTTOM RIGHT OF SHEET A-1. VOLTAGE REGULATION WITH OPTIONAL TEAL UNIT A. 112.5KVA, THREE PHASE, 480VAC INCOMING LINE TO MAIN DISCONNECT WITH 5% VOLTAGE REGULATION UNDER INTERMITTENT NO LOAD TO FULL LOAD CONDITIONS REQUIRED. 60HZ ±0.5%. 3. IF ANY OF THE ABOVE POWER SPECIFICATIONS REGARDING VOLTAGE REGULATION, CANNOT BE MET, THE FOLLOWING CORRECTIVE ACTION MUST BE TAKEN: A REGULATION TRANSFORMER OR LINE CONDITIONER DEPENDING ON THE SEVERITY OF THE PROBLEM SHALL BE EMPLOYED TO MAINTAIN LINE VOLTAGE WITHIN 5F NOMINAL UNDER INTERMITTENT, NO LOAD TO FULL LOAD CONDITIONS. TEAL POWER CONDITIONER NOTE NOTE: IF A LINE MATCHING TRANSFORMER IS REQUIRED, OR IF THE FACILITY IS EXPERIENCING GROUNDING OR POWER CONDITION PROBLEMS, OMEGA MEDICAL RECOMMENDS THE PURCHASE OF A TEAL UNIT INSTEAD OF A LINE MATCHING TRANSFORMER. THE TEAL UNIT REPLACES THE 1) LINE MATCHING TRANSFORMER; 2) MAIN DISCONNECT (A); 3) LOAD CENTER (Al); AND 4) TRANSIENT CONTROL WHICH WILL PROTECT THE EQUIPMENT FROM VOLTAGE SPIKES, ETC. A TEAL UNIT WILL SAVE CONSTRUCTION TIME AND REDUCE CONSTRUCTION COST. CONTACT TOM FISHLER 262-827-9101. ORDER MODEL #PCDU-ORF PER GENERATOR. YOU MUST SPECIFY PRIMARY VOLTAGE: 208 OR 480VAC THREE PHASE INPUT. ELECTRICAL CONTRACTOR SHALL FURNISH AND INSTALL ALL CONDUITS, WIRE, WIREWAYS, DISTRIBUTION TRANSFORMERS, JUNCTION BOXES, ENCLOSURES, CIRCUIT BREAKERS, ETC. ALL WIRES TO BE THHN TYPE, STRANDED COPPER UNLESS OTHERWISE SPECIFIED. THE ELECTRICAL CONTRACTOR SHALL SUPPLY LUG PAIRS OF #8 OR GREATER FOR ALL CABLES LISTED WITHIN THE SCOPE OF THIS WORK. CONDUIT AND DUCT RUNS ARE SHOWN SCHEMATICALLY. ACTUAL BUILDING CONDITIONS WILL DETERMINE CONDUIT AND DUCT ROUTES. CONDUIT TURNS TO HAVE LARGE SWEEPING BENDS WITH MINIMUM RADIUS AS SPECIFIED IN NEC ART. 346-10. IF LARGE BENDS IN CONDUIT ARE NOT POSSIBLE, USE SERVICE ENTRANCE ELBOW CONNECTORS TO AVOID DAMAGE TO CABLE. ELECTRICAL CONTRACTOR TO PROVIDE 10'-0" TAILS FOR ALL WIRES UNLESS OTHERWISE SPECIFIED AND IDENTIFY BOTH ENDS OF ALL WIRES. ELECTRICAL CONTRACTOR SHALL MAKE EVERY EFFORT TO ENSURE THAT POINT TO POINT CONDUIT RUNS ARE AS SHORT AS FIELD CONDITIONS ALLOW. LEAVE PULL WIRE IN EMPTY CONDUITS. WORK SHALL COMPLY WITH REGULATORY AGENCIES OF JURISDICTION. ALL SUCH AGENCIES SUPERSEDE THESE DRAWINGS AND MUST BE ADHERED TO. THE ELECTRICAL CONTRACTOR SHALL BE RESPONSIBLE FOR SCRUTINIZING THESE DRAWINGS AND SHALL MAKE CORRECTIONS ACCORDING TO PREVAILING CODES. NOTE: CONDUITS MAY BE INCREASED IN SIZE BUT NEVER DECREASED WITHOUT CONSENT FROM THE EQUIPMENT REPRESENTATIVES. ELECTRICAL CONTRACTOR SHALL BE RESPONSIBLE FOR 11,.STALLING THE PATIENT GROUNDING NETWORK PER NATIONAL ELECTRIC CODE ARTICLE 517 AND NFPA 70. ALL CONDUIT SHALL BE RIGID TYPE UNLESS SPECIFIED OTHERWISE IN THIS DRAWING SET. ALL CONDUIT RUNS EXPOSED TO WET ENVIRONMENTS SHALL BE MADE LIQUID TIGHT. (e.g. UNDERGROUND, ETC.) ALL FLUSH MOUNTED ELECTRICAL BOXES AND WIRE TROUGHS SHALL HAVE OVERSIZED COVER PLATES. ALL FLUSH MOUNTED ELECTRICAL BOXES AND WIRE TROUGHS EXPOSED TO A WET ENVIRONMENT SHALL BE MADE LIQUID TIGHT. (e.g. IN FLOOR, ETC.) THE ELECTRICAL CONTRACTOR SHALL INSTALL, PROVIDE POWER TO AND CONNECT THE FOLLOWING IF REQUIRED: THE "X-RAY IN USE" WARNING SIGN; THE 120VAC, 15AMP RECEPTACLE AND BNC CONNECTORS; THE DOOR INTERLOCK SWITCH; THE EMERGENCY OFF SWITCH; AND THE 120VAC, DUPLEX OUTLETS FOR SERVICE AND HOUSEKEEPING DESCRIBED IN THE GENERAL NOTES ITEM #6. SPECIAL NOTE TO ALL ANCILLARY EQUIPMENT SUPPLIERS: THE ELECTRICAL SPECIFICATIONS IN THESE PLANS ARE DEDICATED TO THE EQUIPMENT PROVIDED BY OMEGA MEDICAL IMAGING. ALL ADDITIONAL EQUIPMENT SUPPLIERS SHALL NOT USE ANY ELECTRICAL DEVICES CALLED OUT IN THESE PLANS AS A PART OF THEIR ELECTRICAL REQUIREMENTS OR SCHEMATIC. ALL ADDITIONAL EQUIPMENT SUPPLIERS SHALL ISSUE A SEPARATE DETAILED SPECIFICATIONS PACKAGE TO THE ARCHITECT OR TO THE CUSTOMER. THE ARCHITECT SHALL EXTRAPOLATE THIS INFORMATION AND INCORPORATE IT INTO THEIR WORKING DRAWINGS. OMEGA MEDICAL IMAGING IS NOT RESPONSIBLE FOR FURNISHING INFORMATION ON EQUIPMENT THEY DO NOT PROVIDE. ADDITIONAL EQUIPMENT, OTHER THAN O.M.I., DEPICTED IN THESE PLANS HAVE BEEN SHOWN AS A COURTESY TO OUR CUSTOMERS. LISTED BELOW IS THE RELATIONSHIP BETWEEN THE LENGTH AND SIZE OF EACH INCOMING WIRE, WITH THE ASSUMPTION THAT THE POWER SOURCE HAS THE REQUIRED CAPACITY. THE VOLTAGE REGULATION UNDER LOAD VARIATION IS CALCULATED TO BE WITHIN ±5%. BE SURE TO USE WIRE SIZES INDICATED. RECOMMENDED POWER TO THE MAIN DISCONNECT: MAIN CIRCUIT BREAKER: X-RAY GENERATOR: MAXIMUM MOMENTARY: Long Term: MAXIMUM LINE IMPEDANCE: 480VAC, THREE PHASE, 75KVA, 60Hz, WYE-5WIRE 60AMP, 3-POLE, THERMOMAGNETIC EMD TECHNOLOGIES EPSILON 65KW - EPS 65 R/F 105 AMPS / 67KVA 7AMPS/ 4.1 KVA 0.16 OHMS * PROVIDE THE APPROPRIATE WIRE SIZE FROM POWER SOURCE TO MAIN DISCONNECT: WIRE LENGTH LESS THAN 50' 100, 200' ** GREATER THAN 200' FEEDER SIZE LINE: #3AWG #3AWG #1/OAWG #2/OAWG NEUTRAL: #3AWG #3AWG #1/0AWG #2/OAWG GROUND: #8AWG #8AWG #6AWG #4AWG * VOLTAGE DROP CALCULATED FOR LESS THAN 1 %. ** WIRE SIZE CALCULATED AT 300 FEET. IF RUN IS LONGER THAN 300', EC SHALL NOTIFY EQUIPMENT INSTALLER. PATIENT SAFETY GROUNDING CONSIDERATIONS: A SPECIAL GROUNDING SYSTEM IS REQUIRED IN ALL DIAGNOSTIC ROOMS BY SOME STATE AND LOCAL CODES. THIS GROUNDING SYSTEM IS STRONGLY RECOMMENDED IN AREAS WHERE ELECTRICALLY SUSCEPTIBLE PATIENTS MIGHT BE EXAMINED OR TREATED UNDER PRESENT, FUTURE OR EMERGENCY CONDITIONS. CONSULT WITH THE GOVERNING ELECTRICAL CODES AND CONFER WITH APPROPRIATE HOSPITAL ADMINISTRATIVE PERSONNEL AND CONSULTING ENGINEERS TO DETERMINE THE AREAS REQUIRING THIS GROUNDING SYSTEM. IF SUCH A GROUNDING SYSTEM IS REQUIRED, THE RESPONSIBLE CONSTRUCTION PARTICIPANTS SHALL DESIGN AND INSTALL GROUNDING SYSTEM TO INCLUDE ALL METAL OBJECTS AND FIXTURES.
