210.21(B)(1) does not apply (it is not a single receptacle on an individual branch circuit)A 120V receptacle outlet is powered from an Air Handling Unit (208V) to power a cord connected pump. Which sections of NEC 2002 are violated. I believe that the following sections apply 210.21(B)(1), (3), 240.21, 406.3(A). Any thoughts.
REFER TO NEW PHOTO.210.21(B)(1) does not apply (it is not a single receptacle on an individual branch circuit) IT'A A SINGLE BRANCH CIRCUIT FOR THE AHU AND IT ONLY HAS ONE RECEPTACLE???
210.12(B)(3) is only violated if the overcurrent protection is over 20 amps. THE BRANCH CIRCUIT FOR THE AHU IS 60A.
240.21 - we haven't been given enough information - again is only a violation if overcurrent protection is over 20 amps. 60A
406.3(A) - I suppose could be a problem but don't know why that comes up as it has to do with listing and labeling of receptacles in general and is more of a problem with the specific receptacle used rather than the application. AGREE
This install can be legal, but more details are necessary to confirm if it is legal. WHJAT ELSE DO YOU NEED TO KNOW?
One thing I can get from what was described is that if this is a 208 volt air handling unit then to run a 120 volt receptacle you either need a transformer or bring the grounded conductor with the circuit to the unit.
60A (2-pole) with 2#6, 1#8G. Don't know how they are getting 120V out of this?

Maybe was installed when 2002 was in effect?Why are you asking about NEC 2002 violations? It's 2014; we're on NEC 2011 here.

If the OP does not come back with full link it may be possible to reconstruct it.
Hmm... in Fig. 15 there's a transformer. Secondary voltage not noted. Also there are other black and yellow wires with no clear connection to either supply rail. Don't recall OP'er mentioning anything about whether a neutral was run with supply conductors. Don't see any supplementary or transformer secondary ocpd.Try this one:

All the wiring is L-L voltage. Yellow is L1 and Black is L2.
Hmm... in Fig. 15 there's a transformer. Secondary voltage not noted...
Picture of inside cabinet shows model FK4D on document and OP'er also noted model in his link post. Page 1 of the doc you linked associates Fig. 15 with FK4D.We don't know which wiring diagram goes with the OP's unit.
The transformer may be for a LV (24V?)control.
I did not see a wiring diagram where at least 1 yellow wire was not connected to Line voltage.
