TWB2012DR Panel/LinkŪ

The Panel/Link TWB includes a 200A main circuit breaker interlinked with a 30A - 125A generator breaker feeding a heavy-duty copper bus with feed-through lugs. The interlinked circuit breakers keep the generator isolated from the utility at all times, even with the deadfront removed. The TWB is suitable for service entrance and may be used as a main panel or feed-through to a sub-panel or main panel. The TWB has provision for 4/8 branch circuits and is ideal for applications requiring the entire service panel to be available for generator power.

Already have the double throw lying in the garage and waitin' fer me to get my act together on this wiring, trenchin', etc.

The power company is providing that part and I have to handle everything from that box outward. A new service is about the only time that they will stand the bill on the double throw, I'm told.

Thanks,

Allan

just an idea though,check with your electric company,I can buy my wire from them for less than half the cost of goin out and buying it on my own..
HTH,

Here is a better link. see the COPPER FEEDERS

at the bottom of the page

• COPPER FEEDERS

4/0 AL or 2/0 cu is good for 200A in residential services.Aluminum is cheaper. Unless we're talking long distances, if it were mine, I would run "4/0 Aluminum Triplex Type USE" It is approved for direct burial (Underground Service Entrance) so no conduit is needed, but it won't hurt. The triplex means that the two "HOT" legs and the neutral are twisted together in one bundle. Be sure to drive a ground rod (or 2 depending on code) at both ends of the run. I'm a total stranger to you but hope that helps!!

My friend is on his way and I told him what you said. He is picking up the 200A box for the house and enough wire to wire the whole darned place.

Longest run is 90' from the service box outside.

If so are you going to have a aerial drop or underground feeders?

What Size Service Panel in the house 100Amp? 200 Amp?

Do you intend to use Aluminum or copper wire?

All of these factors will need to be considered when sizing the Conductors.

The electric company is coming to re-locate the service and it is up to me to trench the underground and wire from their meter to the house, barn and garage, where by the way, I wanna run my 220 welder.

I know how to wire the darned stuff, but don't know the lingo for wire size. Got a fella headed to Rapid City tonight and he says he'll pick up the conduit and wire, but needs to know the wire size required.

The aluminum is cheaper?

If this house burns down, I'm blaming you by the way. :>)

Thanks,

Allan

I know that much. :>)

Dunno the answer, but.... been looking into this a bit myself of late. In addition to the entrance size, you'll also want to know the distance you're going to cover. 500 feet will require a lot larger conductor than 100 feet. I'm guessing that with about 100 foot you might get away with something like a 1/0 awg triplex... but if you get up to 5 or 600 feet, then mabey you're looking at more like 3/0 awg triplex. I know on the farm here, the 14400 was run to within 50 feet of the main entrance, and then we break down the out buildings from there on triplex. I'd be willing to bet that the cheaper solution will be for you to have the power company bring their equipment as close as possible to your main load center. That damn USEI90 is expensive cable when you go pricing it.... HTH.

2/0 Copper or 4/0 Aluminum for a 200 amp service unless you have a very long run then you may have to go up a size to compensate for voltage drop.

Conduit size is based on % of fill and different types of wire have different wire thickness so after you pick the wire size, type, and you know the number wires you are going to use you select the conduit. Size from a table in the NEC code book.

Here are a couple of links you may want to look at.

you can download you home owners permit application and the electrical wiring handout from this last page.

Oh bye the bye I am not responsible if you burn down you house or poke your eye out. :>)
