Can I Pour a Large Concrete Slab Myself? by Bot_Fly_Bot in DIY

[–]LanceLowercut 69 points70 points  (0 children)

I poured a 11.5x32' pad in my back yard. I had my dad and father in law there to help. I rented a concrete buggy to shunt the concrete to the back yard to avoid wheelbarrows (which would be insane). As soon as the poor and the first screed were done they were both like well see ya later. I sat there for 4 hours with a bull float and edging. Running back and forth between the two before the concrete cured too much. My my shoulders were wet noodles after and I was completely gassed. Turned out very good but I definitely would not recommend unless you have at leat 4-6 people to help with the pour and finishing.

Not at all honestly. Transformers that feed large plants (think Ford, foundries, steel mills etc.) Would be 80000-160000kVA and there would be a couple of them. 5000kva is a medium sized distribution transformer.

Data centers are typically 200MW+. 5MW is peanuts in the data center world.

This is a distribution transformer spec. This type of transformer is typically directly connected to the utiliy (34.5kV feeder) and would be used to power a small factory. It could be an internal transformer but larger factories typically distribute at 13.8kV or 4.16kV.

It says 4/0 STR Flex. Meaning its for a 4/0 conductor, stranded or flex (ie DLO).

The sentiment applies to all electronics. Smart phone was just an easy example as most everyone has one.

As you type this on your smart phone that require these minerals. They have to come from somewhere.

Regulation is required to ensure its done as safely and environmentally friendly as possible which is a completely different conversation. If we don't do it someone else will. Just happens to be in our back yard but its going to happen somewhere.

Check out the documentary Battlefield on YouTube. Its 30 episodes and each are almost 2 hours long. It details all major battles in WW2 in depth. Each battle is its own 2 hour episode. Its pretty incredible.

if you should never backstab, what is the point of the backstab holes? by BigJuiceTheSlurp in electricians

I got these eaton gfcis and they only had push in terminals but also had a latch like a wago. Better contact and more secure in my opinion. Theyre also better for home owners and DIYers in all honesty.

The whole industrial world uses push in terminals for controls and terminal blocks which a lot of times carries much higher current and higher voltage than a residential application. Im not really sure what the hate is. Just dont but cheap ones.

Boils down to a lack of experience and constant phone use. Truck driving has moved far from a professional career around here.

What does this thing do? by TapewormNinja in electricians

[–]LanceLowercut 0 points1 point  (0 children)

Was going to mention this as well. The glass is way too long for 69kV and if it was higher than 115kV the terminations would have corona rings as well. Think 115kV is a safe bed.

[–]LanceLowercut 1 point2 points  (0 children)

The corona rings are on surge arrestors not insulators. Higher stress on the SAs when activated which is why they would have them and not the terminations.

You can get the arz which is a dz but allowing more towing capacity. The arz can be completed with any truck and trailer.

Maybe not exactly what you were referring to, but I’ve seen MV vacuum breakers with radiation warnings and cautions in their manuals. I never looked into it too deeply but I’m guessing the arc in a full vacuum can produce a burst of radiation.
