Has anyone ever heard of this manufacturer? That's right, it's "Simplx", no "e".
They have some breakers in a generator I'm trying to model in SKM. SKM of course has no information on them, and the best I can find on the internet is some similar stuff being sold on ebay.
Thanks in advance,
Tom
I realize that quartz restrike is not a stand alone feature. It just seems to me that quartz restrike would provide sufficient illumination during the HID's relamping period, and that supplmenting it with a pulse-start ballast would be overkill. It would seem that one or the other should do...
Thanks for the responses so far. I have to add though, that this is for a food processing plant, so pendant hung flourescents would not be practical. NSF-certified HID's are the way to go, I just need to justify to the client why we should use quartz vs. pulse-start. On a previous job (not...
Can anyone help me in explaining the pros and cons of quartz restrike vs. pulse-start ballasts on HID lighting? The way I understand it, quartz restrike provides immediate low-level illumination during the HID's re-lamping period following a power outage via a separate quartz filament, while...
Thank you to all for the info. To respond to parts of what has been offered so far:
I do know that this particular client wants to get by "on the cheap", so stainless steel, etc. will probably be frowned upon. This is likely going to be a 2000-2500A service at 480/3, and when I told them it...
I'm a consulting electrical engineer designing my first food processing facility, with limited resources/old projects to refer to in my design.
I am familiar with the types of light fixtures required for these designs, and have already talked with several vendors regarding what should be...

I wrote GE asking this very question last spring, after downloading the book in its entirety. The answer they gave me was basically what other posters here have already suggeseted - since the book was published so long ago, no one at GE has any record of the solutions manual. It is not...
I am trying to determine if a Square D type NEHB panelboard with type EHB branch circuit breakers (both discontinued) can be used in series with a type KI breaker, on a system with approx. 35kA available fault current.
The EHB breakers are rated for 14kA at 277/480, but literature from our...
I just got a callback from the utility. Ultimate fault current is the value if the service transformer is upgraded to the largest size available. Since this will not be happening any time soon, and since doing so would require an entire new service entrance switchboard (currently it is 1600A @...
I can't see the utility voluntarily upgrading the service on their side of the meter. This is a 750 kVA dedicated service for a single "big-box" retail store. The only way it would be upgraded is if the store owner (or some future tenant) requested it, at which point you should redo your fault...
In obtaining available fault current for a 750kVA service being provided by a local utility, the utility rep told me, "maximum available fault current is 17,055 AIC, and the ultimate available fault current is 56,845 AIC."
I didn't ask what the difference was, thinking I could research it...
I get .66 KVA myself, but close enough. Yes, that is the correct procedure.
However, why such a big conduit? You only need 3/4"C for up to 16 #12 conductors, assuming rigid metal conduit.
Also, just to make sure - are you getting that 5.5A number off of the nameplate or shop drawing...
To dpc - I have that exact handout from SEL labs, but it only goes up to 3/4 of page 8. It's obviously been apended since then. Thanks for the updated version!
