1 Metering data data subject to change without notice. Consult local utility for area acceptance. All dimensions are in inches. Metering Data126 Meter Mounting EquipmentEnergization of Electrical EquipmentBefore energizing1) Give equipment a thorough visual examination to determine that: A) Proper clearances have been maintained B) All connections have been made C) Equipment is clean and dry2) Make a thorough physical examination to verify: A) Tightness of all bolted connections see table B) Manually operate all circuit breakers, switches, relays, etc.

2 C) Check rigidity of all mountings, bus bars and components3) All switches and circuit breakers should be in the off position4) Mount covers and close doors*Use 80-in-lbs. when threaded in aluminum bus Torque RequirementsScrew Type Screw Size Torque Tolerances #10-32 30 5 or Phillips #12-24 38 5 1/4 -20 45 5 5/16 -18 60 5 1/4 -20 72 10 5/16 -18 85 10 Head 3/8 -16
