Parallel Breakers ?

Guys thanks for all the feedback.

Sorry it took so long to get back.

As I stated this work is in the office of an engineering firm. In fact one of the nations largest firms. 12 story building w/ over 1,200 employees..

What shocks me the most is they want me to do this work even after I point out the violation.
Amazingly this company preaches safety first at every point.
We need 2 bucks of scaffold to run this feeder and they are requiring all scaffold safety equipment, safety harnesses and certified scaffold builders... all this to reach 14' high.

Back to the issue at hand.

The panel is a 20 year old westinghouse. Originally we were to install a 200 amp breaker. Which was avaliable. later during the disign the increased it to 225 amp. This is when I pointed out a sticker which stated not to install more then 200 amps in one space.
Well they questioned this to the point that we contacted cutler hammer.
Cutler Hammer then informed us that even though a 225 amp breaker is avaliable, the hardware needed is only rated for 150 amps.

This is when the designers devised this parallel breaker plan. I have pointed out the fault and after some discussion they have even offered to provide me with a hold harmless letter in addition to revised drawings to calm my concerns. I am just not getting this warm fuzzy feeling doing this work. But at the same time tough to tell a good customer no..

In closing I really enjoy this board and wish I had time to post more often...But thanks for everything.
 
My only remaining suggestion is that, instead of getting a "hold harmless" letter (which only means that they won't be the ones to blame you, and that it will be others who take away your license), you ask them to obtain a variance from the AHJ. Let them send a letter with a description of their plan to the AHJ, and see if the AHJ sends them back a letter saying it is allowable in this specific case.

This gives you a more useful "hold harmless" situation. If the AHJ says OK, then you can install it. If the AHJ says no, then the engineering company will have to stop pushing for it. If they refuse to speak with the AHJ, for fear of getting a "no" answer, then they would be in violation of the professional ethics clause that is inherent in their possession of a PE license.

(Sorry, but I do have yet one more suggestion: Send them a link to this thread. :wink: )
