Total trip time was electri- <br />cally monitored. <br />3.1.4 System operation was tested at 558 rated voltage. <br />4.0 RESOLTS <br />4.1 The main bonding jumper on panel #1 has been incorrectly <br />sized. This should be 250 MCM per UL Standard 891, Table <br />23.1. ��„� i-,�. <br />" ,/ <br />4,2 The system on panel #2 was found operat-ional and acceptable. <br />4.3 Ground electrode conductors for. both systems, do not appear <br />to be a 3/0. UL 891 table 23.1 specifies that a 3/0 ground <br />electrode conductor be installed. �. ; �;,- ,� % <br />. -•� � � �� ' � � � '�� <br />
