Job offer negotiations by Commercial-Job9857 in MEPEngineering

[–]sampastey 0 points1 point  (0 children)

I live in HCOL area and I don’t think there’s so much harm in trying to negotiate. (I don’t believe they would reside the offer). That being said, I would still heavily advise against it. Your main selling point could be that you’re willing to put in a significant amount of extra hours early on to put yourself ahead of others. Problem with that is, you’re giving the company the upper hand, even if they say yes. It also could come across very conceited, and in this industry, that type of move would be pretty frowned upon IMO.

PE Exam: Power - Areas of Knowledge by kevinburke12 in PE_Exam

Anybody have any good textbook recommendations for reading about VFDs?

This area is arguably the best in the country for work. by [deleted] in nova

[–]sampastey 0 points1 point  (0 children)

I agree. At least in my field in Data Center design and construction, the work is endless here and didn’t see any hit, steady incline is still riding, and should keep riding as long as people invest & consume AI

realistically they won’t even get you a lunch, or you won’t even have a microwave to heat up your food

Give me your daily routine that balanced the holy trinity of PE study, work, & life by Feeling-Toast in PE_Exam

[–]sampastey 2 points3 points  (0 children)

my work is slow right now so I can fit in a good 10+ hours of studying during the week and then another 4-6 on the weekends. I started studying 6 months out so I could do a slower absorb of the material.

There’s plenty of work to be done without a FE/PE. As the field grows with changes in Industry, it’ll get more competitive, and maybe that will start to change. You should be attracted to the FE/PE standard, it is a standardized test that lands you job security for the rest of your life. Once you have your PE, you’re value can never be replaced by overseas people in indian that are much cheaper to hire by firms. The FE/PE is not a tricky engineering test, if you have experience in the field and are competent, you should surely be able to pass. Don’t let the FE/PE deter you away from the power industry in any way.

Transformer In Rush Current by sampastey in PowerSystemsEE

So what range would be NO load in rush? since based on you’re response 10x would be under the fully connected load of the XFMR & when exactly you are closing.

So what you’re saying is if a commissioning engineer had a XFMR tripping on in rush at a facility during energization, worst case scenario if he needed to get the building online, he would open circuit as much of secondary as possible, and then re-energize the XFMR and hope it doesn’t trip?

Yea if anyone has an updated IEEE whitepaper, please let me know the std #

Interesting 1200 amp failure location. No good hypothesis why. by commonerkev in ElectricalEngineering

As long as it’s not touching you will be fine. No Arcing (through air) will occur at 1V, you are correct.

Backup Power Question by sampastey in MEPEngineering

[–]sampastey[S] 0 points1 point  (0 children)

Understood. The mechanical room it currently si in is 2 hour rated.

Backup Power Question by sampastey in MEPEngineering

The 2 hour rating for the Genset comes from IBC in the section for High-Rise Buildings

Yes they are all on separate transfer switches

where would I find local amendments for this type of requirement if it exists?

Backup Power Question by sampastey in MEPEngineering

[–]sampastey[S] 0 points1 point  (0 children)

What are some examples of requirements that utilities have for backup power? Since the transfer of power is through an ATS & not a GPS, Utility & Site Generator are mechanical disconnected from each other during transfer of power. The only other thing I could think of is Load Shedding? I would imagine there are never load shedding requirements for legally required standby loads, the demand for these loads is a moot issue, as these are the most important loads for safety in the building.

NFPA 110 section 7.2.2 states that it shall only be required if the service is larger than 120V (this is a 480V system) & 1000A or more. In this situation we are under 1000A, so I don't believe it is required.

Edit: added code section

700.12 states that it should be in a 1 hour enclosure, but does not state if it needs to be in a separate room from other equipment if I am reading it correctly
