Electrical Substation Design 1

[ludvik]

I am about to start the design of an electrical substation in Jersey City, NJ. I normally design bridges to AASHTO, and am having a little bit of trouble navigating the building and electrical standards. The structure is single story of probably reinforced CMU design.

We have been told by the client that we should use BOCA 1996, and NESC 1999 (National Electrical Safety Code).

Does BOCA reference the Uniform Building Code for structural design and technical specifics? Are the IEEE (Institution of Electrical and Electronic Engineers) standards on substation design normally applicable? I had a look on the IEEE website, and there are a number of standards in relation to fire and seismic design.

Any guidance you can provide will be greatly appreciated.

BOCA is a stand-alone model building code just like the UBC is. They do not refer to one another or depend upon one another.

Chek the IEEE Std 693-1997, "Recomended Practice for Seismic Design of Substations". This standard replace the former version of std. 693-87.

Notice that there are mayor changes regarding the seismic requirement for electrical equipment, foundation and structural support. This standard introduce three seismic performance level (high, medium & Low) associated with defined response spectrum curves in lieu of the conventional seismic zone risk used in UBC, BOCA or other civil structural design standard.
