Default Delco AC Generator 460 Amps

A Greenhouse that I have done work for has a Delco AC Generator for the Boiler Room.
The Boiler Room was built in 1947 with 3 Cold burning Boilers.
I was told that it was Featured in a Engineering Magazine around 47, 48 or 49.
They had a large Vacuum system for the Cold dust and all the piping was brass.

The Model Number is YE-4816 M2
The Serial Number is 35-L-32
220 Volt
460 Amps
140 KW
3 Phase


I do have the Original paperwork with pricing and other information and the Generator seems like it was delivered in 1963.

It has a Automation Transfer Switch that I do have the Instruction Manual

Synchro-Start
Model 1746S4
Serial #41060

This Generator backed up a 400 Amp Delta Electrical Service.
It is a 3 wire system, no Neutral

The Generator runs great but the Transfer Switch has not worked in at least 40 years.
They never asked me to try and repair, long story the person in charge like to do everything Manually...........

So now this old Service Entrance needs to be upgraded to a 120/208 Volt Y system.

I would like to know if anyone has any information on this Generator.
A long time ago they wanted me to replace the Delta Service and replace it with a Y

At that time I thought that I had figured out that this Generator could be wired to supply 120/208 Volt Y

I cannot remember where I found this information, but I would have not told them that it could be reconnected for a Y system if I was not sure I could.

So any information would be a great help.

That is nice looking stuff and I am sure it could be fixed, but before agreeing to do anything, I would insist on redoing all the little hillbilly things, wires all over the generator, oil mess, double and triple tap connections, etc.

It looks like there is a lot of cleanup work to be done before attempting major repair/reconfiguration.

Also where does the hot air from the Detroit radiator go?

It's a long story but Greed was the big factor.
The Greenhouse changed hands a number of times then the Bank took it over.
The roof leaked for a number of years and they only had 1 Employee for a number of years while trying to sell.
They have patched the roof and will replace it this Summer.
And plan on Painting the Boiler Room, I assume the outside for Looks...


Two people from Long Island purchased it a few years back and tried to get the Permit to grow Medical Marijuana.
They did not have the connections so they rented space for different crops and last year they rented space to a Medical Marijuana Company.

At one time this Greenhouse was on of the Top 10 Rose Growers in the World.

I told them to clean and paint the Generator and they agreed.

They have a 4' Exhaust Fan mounted on the wall next to the Generator and sliding doors that can be opened for cooling.

I did work for them for about 30, 35 years when they went to Potted Plants.
Everything is run by Computer, only took 9 Months to get the Original Glass Houses running.

I will be 72 in June and have no interest in doing any Physical Work.
I just give them information on what I installed and understand.

I hate these type of installations. 4' sounds impressive but this engine can make a lot of heat also. And the sliding doors, will the employee that is on duty the night that it comes on line remember to open them?

If there is a 4' opening then the best idea would be to make some duct work from the radiator to the 4' opening and get rid of the extra fan.

Make it work without intervention because if the power is out then chances are all hands will be needed elsewhere.

In the Mid 80's they had converted 2 of the 3 Coil boilers to Oil.
The real thick stuff.
So someone had to run the Boilers and they ran all Winter.

Now they have Three 600 HP Gas Boilers and One 300 HP Gas Boiler that they call the Summer Boiler.
So with the Gas they did not have to man the Boilers 24/7
One of the Managers lived in the house at the end of the driveway and walked down after Supper and the other Manager checked before he went to bed or went drinking......
Truck drivers coming and going during the night who would call if any problem.
The power in their area is very reliable.
Drunks knocking down poles is the biggest problem.

They are connected to a Service that calls if they detect a problem also.

Never had a problem with Over Heating.
But I suggested that when they replace the Service to move the Generator close the the Service because they need to add the Neutral and 4' pipe and 500 MCM Copper per foot carries a big price tag.

Thanks for the idea on how to add more/better cooling

Any idea how many leads come out of the alternator. Hopefully it is a 12 lead so it can be reconnected as desired.

The connection box is on the floor with a side cover and very small.
I never looked inside but for some reason years ago I was thinking it could be connected 120/208 Y

I will be in Florida for 6 weeks so I will check when I get back.

So how would the leads be connected ???

This is something that is way down the road.

Thanks,
Ed
