Hello, everyone.
This is Enta.
I have something I’d like to ask you all!
It's about generators.
We have a large generator at our place.
There may be cases where multiple machines are connected.
Belcon
Blender
High-Pressure Washer
Measuring Instruments
Things like that, for example.
In such cases, use a distribution panel.
Connect it to the distribution panel, and then connect its cable to the generator.
Basically, it means not to use a daisy-chain setup.
But what do you do when a single machine is large?
For example, let's say you have a 100-kVA generator powering a drilling machine, a mixer, and a pump.
So, is there only one connection line to the generator?
In that case, I think the circuit breaker on the distribution panel side would need to be quite large.
When it comes to core drills, the cap tire you connect is 60SQ—which is quite large!
Is the circuit breaker also pretty big? (Is there even such a thing?)
In our case, we connected the 60SQ cable directly to the generator, and
We've also connected the 38SQ cable to the Plus distribution panel.
Depending on the company, some may say this isn't acceptable, while even major general contractors might not point it out.
Which one is actually true?
That's what I'm thinking.
In the case of sprayers, we connect them to the distribution panel, and we connect other equipment separately as well.
A circuit breaker of this size costs just under 300,000 lol
It's safe no matter how far you go, but it's expensive! (And is it even worth it?)
When it comes to electricity, we really don't know much.
The electrical industry has this image of being really specialized, and we in the civil engineering industry don't understand it at all, lol.
If we end up having to say, “No daisy-chaining!” then we’ll have to bring two generators, which will really drive up the costs.
If anyone knows, please let me know.
The question is "Daisy-Chain Wiring in Large Generators."
It seems like it wouldn't be a problem if there were a convenient answer like, "Up to two lines is OK," lol.
Not an answer based on personal opinion, but rather,
I’d like a definitive answer—something like, “It’s written in such-and-such a reference,” or “There’s no problem with this calculation.”
Even when it's pointed out, if you ask for more details, they just brush it off with an excuse like, "It's company policy," lol.
It's that age when you want to know the truth ^^
I bet they'll just say it's fine as long as I don't go over the limit lol
See you later.
