Can any of the EZM 3-phase IN - 1-phase OUT Branch devices (For example EZML313225) be used on a 240 Vac DELTA, 3-Phase 4-Wire System?

Issue:
Product Design Features

Product Line:
EZM Metering Equipment

Environment:
Voltage system

Cause:
Application

Resolution:
No. This voltage system would require ordering the EZM branch catalog number with a suffix 'CA'. For example the EZML313225 would need to be ordered as EZML313225CA.
The standard EZM 3phase IN - 1phase OUT branch devices are limited for use on a 208Y/120 Vac Maximum, 3-Phase, 4-Wire System, providing 120/208 Vac, 1-Phase, 3-Wire Service to downstream tenants (making use of 2-Pole type QDP-TM circuit breakers). These branch units are phase balanced at the factory, based on the number of meter sockets, but can be changed in the field.

The EZM 3phase IN - 1phase OUT branch units with the suffix 'CA' are marked for use on a 240 Vac DELTA, 3-Phase, 4-Wire System, providing 120/240 Vac, 1-Phase, 3-Wire Service to downstream tenants (making use of 2-Pole type QDP-TM circuit breakers). This branch units are bussed at the factory having all meter socket positions connected to A-Phase and C-Phase ONLY where the High-Leg B-Phase (at 208 Vac potential to ground) has been omitted from the vertical bussing in these devices.
