Re: [RE-wrenches] Conduit Bending

[Jerry Shafer]

Mr. Miller
I did not nor would l ever say you don't get your hands dirty, conduit work
is not much different than riding a bike, the best way to stay on top of
what ever you do is to practice. l to have been in the trades since the
70's. lm also a pilot and both require hands on behind the wheel skill and
brain. Developing connections that includes eye hand feel of what you are
operating that as l as sure you have comes with using the tools and knowing
the feel in you hands not on a video on a screen. There are many people
either entering our trade as a result of retraining or through ROP private
or public programs that watch u tube videos and think they are masters of
the trade before ever picking up a bender, this is what l am referring to.

Re: [RE-wrenches] Outback sold to PA battery company

[jerrysgarage01]

WrenchesI spoke to a senior manager at Outback at SPI and they said that there 
they are an inverter company and regardless of ownership that would not change. 
At that time it was only a rumor and they may have been down playing the entire 
idea even after l said that they would be.Jerry

Hi folks, It looks like Outback (owned by Alpha) has been sold to Enersys, who 
has been supplying the Outback-branded batteries for years. 

Anyone have any info as to how this may affect Outback production or support?

I sure hope you are not implying that I don’t get my hands dirty, or that I
am looking for some kind of shortcut, because your message kind of implies
that.  I have been in the trades since 1973.  I have been licensed since
1990.  I have bent EMT, rigid steel, rigid aluminum and PVC.  I have
installed vapor proof, explosion proof and motor control circuits. I have
roped new houses and have done lots of old-work.  I have installed
microwave dishes, spliced waveguide, rebuilt transmitters and installed

work…….   I hope you get the picture.



Getting one’s hands dirty is only part of the answer.  Engaging your brain,
using the best tools you can find and reaching out to other professionals
is the other part of the equation.



In our trade, a contractor does not bend conduit all day every day.  We
sometimes go weeks without touching a stick of pipe.  Therefore, we have to
keep thinking and keep training.



This is why I reached out to the Wrenches for advice.  I hope we can keep
the Wrenches forum as a safe place to ask for advice without fear of being
judged.



Most Sincerely,



William Miller

William,



When one is doing a lot of bending of rigid conduit, where the finished
length of pipe needs to be determined, after all bends are made, and
threading happens first due to bends interfering with the threading
machine, one develops a DOPE sheet. The term being borrowed from long
distance marksmanship, Data On Previous Engagements. One bends scrap pipe
to various angles, and by making marks where the bender makes contact with
both stub marks, and the 45 degree and saddle marks, a cheat sheet can be
developed to help with arriving at desired stub lengths and calculating
“shrink”, the amount that a length of pipe shortens after bends are made.
Similarly a DOPE sheet can be made, or trigonometry can be used when making
concentric bends and segmented bending.

That was the world I inhabited for a decade and a half. Now days, if I get
into that situation, bend and cut : )

I usually do the bend and cut method, because it really is faster and EMT
is cheap.  Look how much time you are already cooking doing research and
exploring various apps, etc?  I too have wanted to be the cool pro, and
bend to exact measurements, but alas, the sun is setting much sooner now,
and I need to get the job done.  Also, I recently picked up a nifty reamer
attachment that chucks up in a cordless drill and finishes the cut end
nicely.  Between that and my porta band saw,  the bend and cut method is
faster and the finished job is just as good.  Actually I just switched to
Metal Clad 6-3 for my PV runs, and it seems better as well.

I look forward to hearing what other more accomplished conduit smiths have
to offer, though.

Re: [RE-wrenches] Commercial backfeed

[Darryl Thayer]

That is a strange panel.  If you are feeding a breaker panel yes you must
be farther from the line connections to the bus bar, unless the busbars are
limited in the total load breakers in which case the other set of rules
apply.  How and what you connect depends upon the service at that point.
 If it is delta not wye, as you said, you have to use a true 480-volt
inverter, not a 277-480 inverter.  The difference is the ground
connection-neutral bond.  The 480 Delta could be grounded as corner ground
making the legs 480, 480, 0 volts, or as a center tap 240-480-volt making
the legs 240, 240, 415 volts to ground.  If however, it is not a delta but
a wye the legs would all be 277-volts to ground.Be sure to check
voltages and with your inverter supplier so you have the correct
configuration.20% of 600 A at 480-volt 3-phase is about 100 kW.  (600 x
0.2 x 480 x 1.73 = 99.600 Watts)
This system will have another transformer, either single phase or 3-phase
giving the 120-volt plug loads.

Yep, all the rules still apply, But with 480 you get far more leeway as far
as breaker size with the square-root factored in.
