Topic: What kind of breaker panel do I get for 300kVA 415Y/240V power setup (Read 157 times)

If you're setting up a 300kVA 415Y/240V power system, you’ll want to make sure you get a breaker panel that can handle that capacity safely. My suggestion would be to look at a panel that supports at least 600 amps. This gives you a bit of wiggle room and ensures you’re not overloading anything. I’d also recommend going with a trusted brand—reliable equipment is key for long-term safety.It might be worth reaching out to a professional service like https://kanatautilitiesltd.ca to get it done right. They could give you a better idea of what specific panel would suit your setup and even help with the installation. Having someone local and experienced always makes things easier.

I am planning out a mining setup that has power coming in at 415Y/240V . This is located in Missouri USA.
I was looking for breaker panels for this setup, but I only see 480Y/277V three phase panels being sold around here an online.

If the breaker can handle a higher voltage than the supplied voltage then that's fine, it's not like the breaker is going to increase the voltage from 240V to 277V, so all you need to worry about is the amp rating for those breakers, but again, as other people said, let the electrician write you the specs or let him source the panel himself.
Okay are you saying you have a 300kva three phase transformer?
You can not run 96 s19s.
3000 x 96 = 288,000 watts
Or 288 kwatts.
288/300 is greater than 80%

Actually, it is not just that, transformer rating is in VA which is not W unless the power factor is 1 which is not going to be the case for him, his PF is probably 0.75-0.8 (should be labeled on the transformer) so that would be a maximum of 225KW to 240KW, and he still got fans and other stuff to power on, I'd say anything above 70 S19s is pushing it.
Anyway, this is a pretty old topic, I hope OP did the right thing didn't burn the house down.

It sounds like an excellent setup you’ve got planned. I’ve run into similar issues before, and finding the right breaker panel for 415Y/240V in the U.S. can be tricky, especially since most of what’s out there is 480Y/277V. I recommend checking out some industrial suppliers specializing in custom or less common voltage configurations.

The breaker panel will connect to 4x 100 Amp PDUs that will run 24x S19 each.
Anyone know where to find the right breaker panel for this setup?

240/300 is 80%
240/3= 80 units tops not 96. In fact maybe 70 on a hot summer day.
I will tell you a trick a 600 volt not amp will handle 600 volts or less
A 480 volt not amp will handle 480 volts or less
A 240 volt not amp will handle 240 volts or less

I do have an electrician, but i'm buying all the parts myself.
Then have him spec the parts! Are they there just for their good looks? No. If they are a licensed electrician, part of their job description and training is them knowing what the Codes are and how to properly spec all parts needed. He has the eyeballs on the ground so to speak to see and understand what you are doing.Ja it will take a bit of time for them to do it and you will be charged for it either separately with actual work billed later or as part of them doing the whole shebang. If they do this kind of work often, odds are they can get some sort of contractor discount on all the gear needed vs you buying it HomeDepot et al. That said, yes, it is good for you to be able to see the equipment list the electrician comes up with so you *can* check around to see how the costs look before actual gear is bought...
Getting tips from random people is not the way to design/build anything.

Because 415/240V is a non standard supply voltage in North America you might have a hard time finding a panel with that voltage on the sticker. Just get a panel rated for either 480/277V or 600/347V with the correct current rating for your application. I suspect those panels will also ‘support’ your lower voltage setup.
If you don’t have an electrician hired yet look into it. They will save you money long term by ensuring everything is up to code and not going to start a fire. Plus they have connections to distributors that sell larger electrical equipment that is not always available to the average consumer.

You get it from the electrician you hire to do this job... Are you trying to do this without a licensed electrician? That would be a horrible horrible horrible idea.
I'd guess descriptions of the breaker panels you are looking at are listing the maximum voltage that they are approved to carry. But that's a question for your electrician.
