Best Way to Add an Addition Neutral Wire

[jason.combs]

When more than three circuits are combined into a home run using one phase more than once in the home run a second neutral wire is needed and can't be added. You can add hot wires using the plus or minus in the wire annotation, but not a neutral.

Can an additional neutral be added?

You can still add addition grounds/neutrals, however you need to do it through the wire properties and not through the +/- signs on the wire itself.

What happens when you don't calculate it?

MJD,

What do you mean by not calculate it?

i've had trouble trying to add (or remove in my case) a neutral, for a 208-2P breaker. i had several of these in one room (just a junction box with 208V-2P connector). individually homerun, i could turn off the neutral from wire properties, but as soon as i tied one to the next for a 4 hot circuit homerun, the neutrals were greyed out and forced on. i was in a rush that day and couldn't take time to figure out what it was doing, so i left them individually homerun (but that's not how my engineer wanted to show them). i don't know revit's wiring rules, as far as when it makes the number of neutrals and grounds greyed out and when you can change them. anyone?
