I know some panels allow for double lugged neutrals but are there any that allow triple?

Wrong section David ![icon_biggrin.gif](https://global.discourse-cdn.com/internachi/original/3X/8/3/83717c74df9b0ce202453063bc4f11baf0ee6b8a.gif)  
  
  
Grounds are allowed to be grouped, not neutrals. Neutrals require their own lug.  
  
Also, all of the white conductors at the 240 volt circuits need to be re-identified.

Upon further review… after a little reading of past posts, here and elsewhere, I was thinking of something like this:  
  
  
Double wiring of neutrals at neutral bus bar.  
Current standards do not allow for this, however, it may have been acceptable at time of installation. Your panel does have a final inspection sticker by the authority having jurisdiction indicating it may have been acceptable at that time.  
Multiple wires on one screw can lead to loose and/or overheating wires and other safety issues. This may also void the UL listing on the panel and thus its warranty.  
Advise consultation with a licensed electrician to verify safety (in writing).  
  
Of course, the sticker line would only be in there if there were one, however I would not mention the lack of a sticker.

If I’m not mistaken this issue was primarily covered by the manufacturers’ specs until recently, when the NEC finally stepped up and codified it. One way or the other this is not a new rule, just a frequently ignored one. I would suggest advising your client to have a qualified electrician correct it, not consult about it. I once had a sparky refuse to do this, even putting in writing that it was safe as it was. I wouldn’t want to be in his shoes if anything bad ever comes of it.
