S285-90-1 PRODUCT INFORMATION Introduction Standards Service Information S285-90-1 provides the installation, Edison Modular Switchgear is designed and tested in operation, maintenance, and testing instructions for EPDM accordance with IEEE Std 386™-2006, IEEE Std C37.74™- rubber-insulated, pad-mounted or vault-style, Edison 2003, and IEEE Std C57.12.28™-2005 standards. - Page 4 The bushings for the customer connection to switch and rent information to the control. When line current exceeds interrupter modules incorporate Cooper Power Systems the minimum trip setting, the control initiates a signal that 600 A dead-break aluminum bushings or 200 A load-break causes the vacuum fault interrupter to interrupt the circuit.
