Hi, 

 

I was wondering if need to understand the application for both electrical cables and conduits for ppd?

  For PPD?  No.  That level of detail to me is for PDD.  PPD is Schematic/Design Development stage of design.  Think bigger picture design here for that test: not conduits vs. cables, but instead, what size service would be needed for the whole building?  Where might a transformer be located on the site?  Things like that.

  I would say as well, even for PDD, I don't know that you'll get into such nitty gritty for electrical work.  I don't recall being asked about cabling and conduit on that exam.  I would have general knowledge of it, yes.

  Hope that helps.

  Thanks David! you have been really helpful!

  so in terms of transformer location and types. this is how i understand.. 

  location- either outside, underground or inside by need ventilation - for fresh air as they tend to produce a lot of heat while working 

  and types - there are two types - step up and step down? it seems like thee are more specific type. but i guess those will be too specific for the scope of this exam?

  What are the other considerations for locating a transformer?

  Transformers: draw the shortest line from the nearest road to the nearest pony on a building…the transformer is located 4’ from the road on that line. (For underground lines).
