not enough set screws on neutral bar

[rosie06]

In a customers house a 100 amp circuit breaker panel 24 circuits only has 16 set screws on neutral bar without putting 2 wires under the same set screw what is the easiest fix for this

add another neutral bar (some manufacturers have "piggy back" listed extension bars)

You could take two circuits on different phases and splice/pigtail their respective neutrals together and hit the bar with the one pigtail. I like nakulak's idea better.

Would that not create an multiwire circuit and trigger the rule for a common disconnect?

I see the logic behind the question, but I would thing that, being in the same enclosure as the origin of the circuits, it would be visible and obvious, and there'd be no need for anyone to disturb the splice anyway.

Then do it for the groundings instead of the grounded concuctors instead. Bring two (or even 3) together under a Greenie, and terminate the single ground to the bar.

I see that as problematic the intent of the language in 408.41 was a result of a UL Std which required the grounded conductor of each circuit be individually terminated to allow complete disconnection of the circuit during service. I don't have the std No but it is in the ROP of that year

How would the new subsection 200.2(B) Continuity ('08 NEC), affect this type of installation?

Good question, one would need to examine the definition of a MWBC to see if it fits.

From what I read in the handbook,no. The handbook seems to say it's to keep you from connecting a grounded conductor to a ground connection like a grounded bushing.
