General Information EZ TRANSFER OPERATOR FIELD INSTALLATION KIT (GENERAC MODEL NO. 05447) • • • • • • • • Figure 1 — GenReady Advanced Panelboard with Operator Transfer Operator 15A, 2-pole circuit breaker for Utility sensing 125A Lower Panel Generator Circuit Switch Hold down bracket.
General Information TRANSFER SWITCH MECHANISM TRANSFER SWITCH DATA DECAL This transfer switch consists of a Utility and a Generator supply 2-pole switch which feeds a common bus (the lower half of the panelboard). The switches look similar to a circuit breaker but do not have internal current sensing components. The two switches are mechanically interlocked so that both sources cannot feed the common bus at the same time.
Installation INTRODUCTION TO INSTALLATION This equipment has been wired and tested at the factory. Installing the switch includes the following procedures: CONNECTING POWER SOURCE AND LOAD LINES • • • • (NORMAL) and GENERATOR (STANDBY) Mounting the enclosure. Connecting power source and load leads. Connecting the generator sensing and transfer relay circuits. Testing functions; manual and electrical operations. UNPACKING Carefully unpack the load center/transfer switch.
Operation Conductors must be properly supported, of approved insulative qualities, protected by approved conduit, and of the correct wire gauge size in accordance with applicable codes. MANUAL OPERATION Be sure to maintain proper electrical clearance between live metal parts and grounded metal. Allow at least 1/2 inch for 100-400 amp circuits. Manual operation must be checked BEFORE the transfer switch is operated electrically.
Operation VOLTAGE CHECKS 1. Turn ON the UTILITY power supply to the transfer switch using the UTILITY service disconnect and 125A, 2-pole circuit breaker for lower panel feed circuit breaker. PROCEED WITH CAUTION. THE TRANSFER SWITCH IS NOW ELECTRICALLY HOT. CONTACT WITH LIVE TERMINALS RESULTS IN EXTREMELY HAZARDOUS AND POSSIBLY FATAL ELECTRICAL SHOCK. With an accurate AC voltmeter, check for correct voltage. Measure across the terminals of the UTILITY voltage sensing circuit breaker.
Operation ELECTRICAL OPERATION Test transfer mechanism electrical operation as follows: 1. Verify the Utility Service Disconnect (200A) and the 125A Utility lower panel feed circuit breakers are in the ON position. 2. Verify the transfer mechanism is in the Utility position. If not, refer to the Manual operation section and move it to the Utility position. 3. Refer to the appropriate owner’s manual. Be sure the standby generator is prepared for automatic operation. 4.
