A 7 storey building has a floor area of 35,000sq.ft on each storey. On the ground floor 11KV electrical sub-station is to be erected. A load of 3kw for every 400sq.ft (p.f is 0.8) is proposed for each floor. fire pump 7.5hp, water pump 5hp, lift 2 nos, each 10hp and 20shop load of each shop is 5kw. calculate a. load each floor b. total load of building c. L.T feeders for aech floor and from transformer to main. d. distribution diagram e. capacity of sub-station/capacitor bank f. line diagram

hey guys i scored 910 on GRE and 67 on TOEFL respectively.I have an aggregate of about 74%in my B tech.For which colleges should i apply for an MS program in electrical engineering.I am looking for colleges in NJ,SC,NC,GEORGIA, NY. Please reply with a good response.....
following are the questions asked in interviews: 1) Considering the short circuit fault, which switchgear is preferable, SFU OR MCCB? Which operates faster? whicg one is popular in Indian Market and why? 2)Define SCPD. What is type2 coodination? 3)Why the contactor rating is higher for the fuseless selection than for fuse selection? whether the ratinf of SFU or MCCB remains the same in both the cases? 4)If the HP rating is known then can you calculate the ratings of L.V Switchgear(SFU/MCCB, contactor, OLR) without using the selection chart?
Is it possible to download the Siemens Selection Chart(TYPE 2 coordination) for 1) fuseless selection 2)Fuse selection

I want to put this query to SENIOR & EXPERIENCED ELECTRICAL ENGINEERS. 1)I want to know about the control circuit diagrams for control panels. I found it difficult to understand. Is there ant booklet through which we can learn the circuit diagrams? 2)I want to learn about conduiting, laying cables, preparing cable schedules and various techniques which is the part of building infrastucture(construction field). I don't have any experience in this area. I have experience in control panels only. that's why i am not getting any opening in building infrastucture (construction field).Can I get the job in this field as Trainee Engineer? How to enter this field? I need job in PUNE
