Friends:
I have ordered a Class 320 Meter/Main/Combo. My vendor informs me there are new codes that apply to these cans, specifically in 230.71(B), cited below: *(B) Two to Six Service Disconnecting Means. *Two to six service disconnects shall be permitted for each service permitted by 230.2 or for each set of service-entrance conductors permitted by 230.40, Exception No. 1, 3, 4, or 5. The two to six service disconnecting means shall he permitted to consist of a combination of any of the following: (1) Separate enclosures with a main service disconnecting means in each enclosure (2) Panelboards with a main service disconnecting means in each panelboard enclosure (3) Switchboard(s) where there is only one service disconnect in each separate vertical section where there are barriers separating each vertical section (4) Service disconnects in switchgear or metering centers where each disconnect is located in a separate compartment Here is an analysis, apparently from Siemens: Apparently there are factory partitions required now and some models have them and some do not. Of course the one I specified, advocated for and that is cheaper does not have the partition. I don’t want to order the wrong one so I am looking for verification I am understanding this correctly. Have any of you run up against this when ordering these devices or having them approved? Thanks in advance for any input!
