duplex service


what would be the best way to feed two meter panels from one service drop. i am working on a new duplex - the utility will only give me one set of wires to the building but I want each unit to be separately metered.

if i have two 200 amp panels outside, mounted next to each other that are set up for either ug/oh entrance, can i run the service wires into the bottom of one of the panels - through the lugs of that panel (pass thru) out the top and then pipe over to the other panel?

buying two 200 amp panels costs about $200 - buying a duplex meter panel is about $600.

this is the panel I am considering

Before you go buying anything the utility needs to connect to you need to make sure it is on their approved equipment list.

You could run 2 parallel service cables from the overhead drop.

duplex service


there will be two meters

the service connection will be underground and will only have one set of conductors

can i run the conductors through the lugs of one panel and onto the next panel or do i need 400 amp bus type panel that would take the service wires and then branch into each meter panel?

there are many code legal ways to do it, but it depends on what your local utility will allow

bring incoming service to small gutter/wireway, tap off the single POCO feed to each meter, then from meter to each panel or outside disconnect if required.

would you need a triple lug inside the wireway to tap the service entrance wires and then feed two panels?

Techy.,

Some POCO's will not approve the wireway with two meter socket on duplex set up.

amsfife.,

I will post the photo what common duplex meter socket look like. it will look cleaner installement.



There are few other verison but again just tell us what POCO area you are on I can or other can able look up what the approved listing is so you can get the correct one.

However there is one gotcha with duplexs I know in State of Wisconsin the homeowner of either side of Duplex building are not allow to hook up the duplex meter socket they have to be done by electrician but for single house with duplex meter socket it may allow the homeowner to do it themself due it is one building but duplex is treated as 2 buildings with common wall that one reason why it have to be done by electrician.

Other states may varies some degrees but not far off from what I comment and I know in France they don't let homeowner deal with duplex meter sockets at all {It don't matter if single building or "two" building with common wall }


Merci,
Marc

You absolutely CANNOT do it this way. The two ways mentioned are the easiest, with a duplex meter pan being the easiest.

Do you need main breakers at the meters? If so then a duplex meter/main is your best bet. I have no idea who quoted you $600 for one though. If that is accurate then you got quoted full list price which no one pays.


Also, cluing us in as to your location will help. Maybe someone in your area can tell if something is legal or not or a common installation.

On top of all this I have to say, this is NOT really DIY work. Is this your place? Will you be renting it?
Since this is a service at least you are forced to get it all inspected.
