Ben H Posted August 21, 2011 Report Share Posted August 21, 2011 Maybe their grid is not designed for a bunch of 200a loads. I can't imagine a lot of places large enough to even need a 200a box in the city. Could be a city restriction. Just a guess. Quote Link to comment Share on other sites More sharing options...

ghentjr Posted August 21, 2011 Report Share Posted August 21, 2011 When high rise building have many panels which are fed through conduit there may be a heat issue and therefore a reduced load requirement. Just a guess. Quote Link to comment Share on other sites More sharing options...

allseason Posted August 21, 2011 Report Share Posted August 21, 2011 From what I hear you cannot use PVC drain waste and vent in NYC, all metal and lots of cast iron. Has to do with toxins when it burns. Gotta look out for those 7 to 8 million people. Quote Link to comment Share on other sites More sharing options...

Used to be the same in many areas around here, but it had to do with politics as the pipefitters union is based in Chicago. Quote Link to comment Share on other sites More sharing options...

Darren Posted August 21, 2011 Report Share Posted August 21, 2011 I don't know about residential, but commercial buildings in NYC did not allow romex or BX; had to be conduit. Quote Link to comment Share on other sites More sharing options...

Pretty sure it's the same in Chicago, residential and commercial. Quote Link to comment Share on other sites More sharing options...

John Kogel Posted August 22, 2011 Report Share Posted August 22, 2011 One reason for metal pipe is to slow the spread of fire thru an apartment building. I think that applies to everywhere, not just NYC. I will guess that NYC required extra testing for approval of that panel for more than 100 amps, and the CH people just said screw yous, we'll just downrate the panel rather then spend that extra time and cash.
