Power mains question: wire gauge

So it's not a "machine shop". Giggle. Get real, Michael.

You're the one doing the humping, Michael.

Not anymore. He worked for a schoolboard in their maintenece complex. They had a MACHINE SHOP, cabinet shop and garage where they did maintenece on all their vehicles. They had in house support for everything except new costruction & roofing

Keep showing your petty ignorance.

You did, and you decided to move there so you're the fool.

That must have been a tiny shop.

He said he was going to suggest it to the owner, so who knows.

Some people also pull THHN or CAT5 off the box spool the same way, also makes a mess. It takes more time but if you spiral (cable) your bundle the pull cord will not get mixed. Never has for me.

Hardly, but you're dreaming again.

So why not 500KV? You never know?

Still dry humping? Come on, Michael. Drop it already.

More dry humping from Michael. I hope you feel better soon.

The biggest thing is to make sure the wires go in straight. Kinks or twists will make life miserable later. I've seen people pull Romex off the center of the roll, without unrolling it. It makes a mess; bad enough when pulling through rafters but it's a disaster in conduit.

You should. Obviously.

It doesn't matter what *YOU* have on hand. #12 works just fine and is about 1/3 the cost of #10.

Almost *NEVER*. In this case, it's *STUPID* to even suggest it.

Wrong. There is no corners cut at all. You're lying, just to make some sort of point. You're wrong. Step up to it.

What *YOU* did *100 YEARS* ago is irrelevant.

Why not put the compressor where the power is, and run an air hose? Then we could argue about ths size of the hose.

Actually, that's what I plan to do. Put the compressor in the garage and pipe the air downstairs. 4" oughtta do it. ;-)

I just have to figure out how much work it's going to be (how things line up).

Hose? What's wrong with iron pipe? Good old fashioned black iron pipe. That has been beat to death on news:rec.crafts.metalworking

I know that you're a fool.

Where is it in the NEC that you can 'spiral the wires'? They don't even allow you to tape them

Where does it say I can't twist them as I feed them?

You're the one inventing "machine shops" out of thin air. Go figure.

Pressure would remain constant. Flow *can be* constricted over that distance.

Think hysteresis. Pressure does have a slight drop as one "loads" the available flow (stored energy). Once you cross that threshold and the flow rate becomes the bottleneck, pressure can drop on a continuous duty "draw".

Just run plastic pipe. They even have tool-free fittings for pneumatic service.

Pretty expensive at the per foot level compared to modern plastic solutions.

And hose would work too.
