Thank you rcwilson. That makes a lot of sense now. You are correct on the first paragraph, that was my intention. Cable in 2000A to 2 seperate line side lugs landings of the breaker. Load side to horizonal cross bus which distribues to small 800-2000 feeders. With a 4000:5 we need to bring the...

See attached picture for arrangement clarification. The picture is a top view of the breaker, there would be another set of stabs below. I have a source for the 2000:2.5 C100 CTs. The costs I will save is in copper bus...

Clarification on the configuration. The breaker has 6 connections on the line side and 6 connections on the load side. The breaker is rated for 4kA. The phase currents are split in half, so A1-B1-C1 on left side of breaker and A2-B2-C2 on right side. Let's say it's a main/feeder. Each leg is...

This question pertains to the usage of relay class CTs for protection and metering in low voltage switchgear. In the case of using a double wide breaker (meaning 2 connections per phase) typically the two split legs of a phase are bussed together in order to run through a single CT. For...

We discovered the solution to the problem. It required editing a .XML and loading it into windchill. Apparently the default setting prevents allowing this parameter from being edited. We needed to remove the setting in the .XML file. Why PTC does this...I have no idea.

I am a site administrator.. but fumbling though the labyrinth of settings. Do you know where I could find the Modify Identity permission?

I understand what you're saying. And this is the problem I am trying to prevent. Unfortunately we design and develop entirely new products from the ground up, with no ability to predict how many part numbers will be required and if the product will go to market. It looks like the number can...

I am a mechanical engineer and working with the system administrator to implement Windchill 10 at our company. Once a part is checked-in, we would like the ability to rename the "number" in the system. We often start a new product with names like "block" and "screw". Once a product moves...

We ended up waiting for a humid day (65%) and making bastardized gauges to the plastic body and face cap. That seemed to appease management. I wonder if this will become policy, or if they will forget about measuring threads in the future. My guess is that they will forget.

My drawings in the new Creo Parametric have been doing some odd things. Within the same working directory, one drawing will have fuzzy looking lines (large to mimic pen weight?) and another will have the older crisper one thickness lines. I've gone and checked my pen weight file and made sure...

KENAT I really like the denial impression method for first piece. I will be using that in the future. Patprimmer I completely agree. I made all of the same arguments in multiple meetings, especially how ambient conditions dimensional change nylon. I may use your last line there in the next...

I should have also specified that the user will be screwing and un-screwing the face cap on a daily basis. The amount of force to removed the face cap laterally would be extreme(tons), not something I need to test. The face cap is hand tightened. We have had problems in the past of receiving...

I am looking for information on best practices of measuring internal and external molded threads. I currently have a impact modified nylon (as well as some additional proprietary modifiers) injection molded (USA made) part with a nominal wall of .100" and a external thread of 1.660-16 UN-2A...

Let me give it a try. I just don't want to include additional sweeps that could get flipped 180* when the model is turned into a flexible component. Trying to keep it tidy and modifiable. Trying to keep just one path for the VSS. BTW I am running Pro/E 5.0

I've just started to play with some of the more advanced features in Pro/E and found an interesting modeling problem. Let me start by saying, yes I know you can download the wave spring models off of Smalley's website, but I'd like to know how to model it myself. I've figured out how to draw...
