Depending on your interest and current understanding, ALL of the books
by Mike Holt are strongly recommended.
His electrical theory series (I think it's 4-5 books) is excellent from
beginner through advanced. Based on what I've seen here... there's one
on AC, motors and transformers that would be helpful to a lot of posters.
FINALLY HE GETS IT!!!
Instead of trying to answer questions that he's not qualified to answer, he
ASKS a question to further his knowledge!
We can only hope that this is the start of a new trend for Dido!
Good going Dido!
Are you seeing this, Stormy??
It would be really nice if we could get the both of you to understand this
Call it what it is....a Corner-grounded Delta. If you look inside the
disconnect you'll see that A and B phases have normal fuses. The C
phase will have a "solid neutral" which is basically a piece of copper
tubing with a UL sticker on it. If you look closer you will see that
that phase is taken to ground, which is why you were measuring 0 volts
to ground on that phase....because its already grounded.
Typical response from you Oscar_Sucks......no technical discussion
whatsoever. What's the matter Oscar? Still peeved about how I've
shown repeatedly how you and your butt buddy fellow minions are
complete idiots when it involves the electical requiements of the very
equipment that you install? Or is it just that the topic is over yer
head? Have you and Boy Paul figured out the difference between MOP and
You are obviously a wanna-be EE, but more likely an unlicensed electrician
operating out of a Pinto Stationwagon. Your self-promotional behavior,
along with your need to be the recognized expert are just symptoms of your
sociopathic tendancies. My guess is that your mother was a whore or a crack
addict, and you were taken away from her at a very young age and raised in
foster homes and state institutions until you were 16. Your lack of bonding
with a parental figure as a toddler is quite obvious.

Damn Oscar, you can make a contribution! Now go insert that treatise
of your's in the charter for alt.hvac and you'll have a perfect
description of the majority of puds in this NG. I merely respond in
kind, so, if you perceive me that way, my job is done, as you're only
getting back what you give.

Geeze... I get busy for a couple of days and you guys go nuts on Volty.
Volty and I have had some debates in the past... and rarely agree. This
is another example of that.
Volty immediately made the assumption this system was a corner-grounded
delta. In my business, I can't afford those kind of assumptions...
Corner-grounded deltas are around... but they're most likely in older
facilities that, in trying to comply with new code... have grounded
their floating delta systems. For the un-initiated, this is done to
insure a quick circuit (fuse) clearance in the event of a ground fault.
I've never seen this done on a smaller system (less than 500 kVa)
because it's usually cheaper just to upgrade the whole shebang.
Dido said (I think) this was a separate 3 phase service for running a
couple of 25 hp compressors. That should be somewhere around 70 kVa.
Anybody throwing that together would use a open delta because it's
cheap.... 2 transformers instead of three.
In certain configurations, especially if the service only provides 3
phase (open deltas are great for single phase services too) one phase
will float ground potential all over the map...
