Genny Genny who can I turn to

Would it be possible to run two independant services off one generator?
The customer has two houses on his property each with its own 200amp service.
My thought was to build a pedestal with the two meter sockets and two
service entrance rated ATS's near the generator.Would there be code issues
with this setup? How would any of you generator guys do the control wiring?
Thanks in advance and waiting to hear from you all...Ed

If the ATS's opened the circuit with the generator still running. It should work. With two disco's at the generator. One more at each house.
The controll wiring, to charge a battery?
You could get the generator that has an altenator to charge the battery.
It will crank once a week.

 

[Ed Carr]

To be more specific this would be a Generac 45kw with two 200amp
service entrance rated ATS's also Generac/Guardian-Ed

The trick is figuring out which ATS will start and exercise the gen.

 

[Ed Carr]

Marc,The only chance I see of both services not being interupted would be if one of my
underground feeds from the utility pole to the pedestal was somehow compromised.
That said I would think I could pick either one to control the generator.Do you see any code issues? Ed

Ed, are you running solid neutral or switched neutral transfer switches. If solid, you'll have parallel neutral/ground paths from the gen set to the transfer switches. As far as starter wiring, parallel the start signal from each switch.

Rick,solid neutrals, and your point was exactly my worry.I can get the switch in a
3 phase version thus being able to switch the neutral. Then this would be a separately
derived system..yes?
Thanks, Ed


The beatings will continue untill morale improves:grin: (saw it on a t -shirt)

Very clever title, try calling 867-5309

You will need to switch the neutral, I'm doing one right now that one generator feeds 6 meters, all the same customer, but they wanted it seperated out in case they sub leased some of their space. Control is easy, you just parralell all of the start contacts from each transfer switch. Most switches use a dry set of contacts to start the generator so multiple power supplies are not a problem. With generac the excerciser is built into the generator, so excercising is not a problem.

Yes it would be a seperately derived system and a grounding electrode system needs to be installed.

Without switching the neautral what is the danger?
I see the parallel paths so that would be the code violation?

Ed

The code article is 250.24(A)5 and 250.6(A). The danger is the potential for some one to get nailed leaning on, working on electrical equipment. The metal frames and the ground wire are carrying current. It would be the same as getting in between the neutral conductor if you lifted the ground wire even though it is a parallel conductor.

If I were to do this install there is another factor involved.
Because these are two existing services the load side from
the two ATS's would be 3 wire.I plan to move both meter sockets
to a pedestal located between the 2 houses.Each side of my pedestal
would have an ATS and a meter.As stated in earlier posts these are
service entrance rated switches so they are the first means of
disconnect.What do you guys think?

Thanks..Ed

IMO i think your messing with mother n.e.c.ture. If you go with the solid neutral, you have parallel currents in the generator feeders, and if you switch the neutrals and keep the existing 3-wire to the houses, you'll lose your ground fault return path.

I thought of this yesterday, but did not have an opportunity to post.

This is brilliant! A nationwide chain of generator sales, service and installation stores. One call gets them all 1 888 867 5309.
The ad is already written, everyone knows the number.

The number is copyrighted.

Brown University transferred the number to Gem Plumbing & Heating[7], a local business. In 2002, Gem began using the number in advertising campaigns both in Rhode Island and in eastern Massachusetts (area code 617). Gem trademarked the number in 2005.

In 2006, Benjamin Franklin Franchising LLC, a large national plumbing firm, began using a toll-free version of the number (+1-866-867-5309). In 2007, Gem brought suit against Clockwork Home Services, the parent company of Benjamin Franklin Franchising, alleging a violation of its trademark. Clockwork contended that Gem's trademark was invalid. Effective in May 2007, Clockwork was ordered by a court to stop using the number in New England. [8] [9]

Well, there goes my latest get rich quick scheme. It's alright, I was gonna have to cash in my Enron stock for the start up capitol.

But what became of Tommy Tutone?

A one-hit wonder with a really cool website: http://www.tutone.com/main2.html

But what became of Tommy Tutone?

he was hunted down and beaten to death by an irate telephone
subscriber with a number that suddenly was way too popular.

could you imagine having your phone number be a "one hit wonder"?
wouldn't that be fun?

everytime the song got airplay, you'd get 50 calls....
