Compatibility and maintenance points
1. Brand compatibility
Murray and PL/ES: Murray load centers can use PL/ES grounding bars (such as ECGB10) and conversion kits (such as MBK150M), but attention should be paid to current matching (such as 125A Murray only compatible with MBK100M/MBK125M).
Circuit breaker compatibility: PL/ES series supports QP/QT/QAF2 series, EQ ® The series supports QR2/QRH2 series and cannot be mixed.
2. Maintenance and safety
Line terminal barrier: The main circuit breaker type load center produced after 2017 comes standard with barriers (such as ECLTB1 compatible with 100-125A, ECLTB2 compatible with 150-225A) to prevent accidental contact.
Regular inspection: The grounding bar connection torque must meet the requirements (such as 45 lb ins for 2/0 wires and 340 lb ins for 300kcmil wires), and the neutral wire must not be loose.
