Had a homeowner ask about a home inspection that said her panel was in code violation by having more than one netural under one screw. House is about 15 yrs old.My question what code cycle was it changed to one netural per screw. I thought the 96 code can i get some help so i won't have to research it so much Thanks

It changed more recently then 15 years ago but not sure when.
 
408.21 Grounded conductor terminations. First appeared in the 2002 NEC. It was renumbered in the 2005 to 408.41 and remains the same in the 2008 NEC.

Actually if the neutral bus is listed on the label for more than one wire it's allowed as long as the wires are the same AWG.

Take a look at the sections I cited.

In a panelboard each grounded conductor shall terminate within the panelboard in an individual terminal that is not also used for another conductor.

also ive seen this on the little sticker inside the panel. it says one neutral per screw but you can put 2 EGC of the same AWG under the same screw. 110.3B comes into play also since thats how the equipment is listed as.

funny thing too, every old panel i work in seems to never have enough space. they all have the neutral terminated with that circuits EGC under the same screw. FPE panels are all like this around here
 
Thanks for the speedy reply... I checked the termations and they were tight also I would have changed them except they would have not reached and would have had to splice most all of them and I feel that would have been more of a problem .Don't like to splice any more than need to.. Wish Home inspectors would get a little more training..

Agreed.

I can't tell you how many times I have gone on a servie call to find a burnt neutral wire because of a poor connection because of multiple wires under the termianl screw.

Sometimes home inspectors are a great source of work for electricians. If that were my job I would have added a ground bar kit near the top of the panel so no splicing would be required.
