What is required for adding the current design EZM devices to an existing OLD style EZM metering line up?
Issue:
Product Design Features
Product Line:
EZM Metering
Resolution:
First, one must keep in mind adding current style EZM to the OLD style EZM will depend on the existing catalog numbers and how the OLD style EZM is mounted in reference to the grade level (ground) or a floor, and to determine what catalog numbers of the current style EZM can be added. It is suggested to obtain ALL current catalog number drawings BEFORE obtaining any device to determine if the current style devices can be added.
If the existing EZM is OLD Style and predates 1998, then a transition section will be required to connect the old main horizontal cross bus to the current main horizontal cross bus. The required transition sections for this purpose are catalog numbers EZM1TRANR (right side) and EZM1TRANL (left side) for single phase systems and EZM3TRANR (right side) and EZML3TRANL (left side) for three phase systems.
