Why the voltage matters
This five-jaw branch unit is documented for 208Y/120-volt service; it should not be described as a generic 120/240-volt meter stack. Jaw count, phase arrangement, bypass method, and utility requirements must all agree.
Project approval checkpoint
Verify the full nameplate, adjacent EZ Meter-Pak sections, tenant breaker provisions, bus rating, and local utility approval. Metering equipment selection and installation should be handled by the serving utility and qualified electrical professionals.
