New electric service
Hello,
I am adding new service to a property and the electric company is installing a 320 amp meter (Needs lever disconnect and they said they have no specific meter requirements other then that). My question based on research:
That this is the maximum continuous load for the box.
Based on that I should get a 400 amp main rated for a 320 amp meter socket (320/400A)??? I want a combination unit because we are running directly off this to multiple locations when we build.
That is were I am confused because they do sell 320 amp main sockets as well but their are very few combination 320A units.
A 200A box is rated for 160A but a 400A is rated for 320A??
Any help would be appreciated.

Off of the 320 amp meter socket you can install a single 400 amp panel, two 200 amp panels, or a combination that equals 400 amps as long as there are 6 or less main disconnects. It might be more difficult to find a combo unit (panel and meter socket) so you may be better off getting a separate panel(s).

Thanks for your response! I talked with 3 different electricians and had 3 different answers. The Siemens unit below takes the class 320 lever bypass meter socket. Do you think this is correct?
The MM0404L1400RLM comes with a class 320 lever bypass meter socket and provisions for 2 main breakers up to 200 Amp each. The breakers are not included. This panel allows the user to feed up to two 200 Amp rated load centers. The panel will accept the QNR (150, 175, or 200 Amp) and QP type double pole breakers (60, 70, 80, 90, 100, or 125 Amp). The enclosure is rated NEMA Type 3R (outdoor use), confirms to UL standard 50 and is fabricated using Galvanized steel with a baked on polyester powder coating. The panel is rated for overhead or underground feed applications. For overhead feed, use the Electric enter "HD" class of hubs (EC56854, EC56855, EC56856, EC56857, or EC56858).

Yes that will work. Seems a little pricey for no breakers included.

To make matters more interesting I just spoke with the Electric company (The person who came out to do the inspection for new service); He told me that there is no restriction on the number of spaces in the box as long as it is a class 320 with lever bypass.
So for the same price I can get this one (Which includes a main breaker):
Last thoughts?
I appreciate everyone's help!

Siemens MC0816B1400RLTM
The MC0816B1400RLTM comes with a class 320 lever bypass meter socket. The load center portion is provided with one 200A main breaker and an 8 space/16 circuit interior with feed thru lugs. There is also a provision for an additional main breaker rated up to 200 Amps. The construction allows for the 8/16 circuits inside the panel to feed exterior loads while also providing the ability to feed up to 2 more load centers from this panel. The 2nd main breaker provision will accept the QNR type (150, 175, or 200 Amp) and QP type double pole breakers (60, 70, 80, 90, 100, or 125 Amp). The enclosure is rated NEMA Type 3R (outdoor use), confirms to UL standard 50 and is fabricated using Galvanized steel with a baked on polyester powder coating.

That's a good cabinet. Provides a lot of flexibility for future reconfiguration if needed.
Residential equipment is always 320A continuous, 400A max (or 160/200). You'll hear both ratings depending on who you're talking to.
