Issue:
Product availability
Product Line:
EZM Metering equipment
Resolution:
Due to NEC SCCR requirements, the only secondary surge protective devices(SPD) that can be used are the below part numbers in the table, along with the mounting kit part number MMSAMK400 that can be field installed inside EZM main devices. See the attached instruction bulletin for the mounting kit
NOTE: The horizontal cross bus in EZM main devices has been drilled and tapped to accommodate the screws and ring terminals provided in the MMSAMK400 mounting kit. The MMSAMK400 is NOT configured for use inside an EZM branch unit.
Another potential option would be to use an EMA surge device, which is externally mounted. For this option, it would require the use of an appropriate sized additional EZM main lug terminal box within the EZM line up and connect the EMA inside this additional main lug terminal box to the main lugs. The lug sizes in the EZM terminal boxes will accommodate the wires for the EMA. It would be recommended to obtain the EMA reference document 1310CT0202 and the EMA series Instruction bulletin document 8222-0014.
