In wiring a house, I have each room's wiring pulled to a junction box in the attic. Each junction box will be a circuit, with a home run going from the junction box to the panel. There are more wires than a single wire nut can join. Do I use jumpers to group the entire bunch so that that all wires (hots to hots, neutral to neutrals, of course)? These are all #12 & #14 Romex. How many wires #12 can I join with one blue nut?

Thanks,

A Blue Scotch-Lok made by 3M is probably the best made, and only handles 6 #12 wires.

You may be better off using a split bolt, see picture, so that all the wires are together, and minimizes the amount of splices. After tightening the split bolt onto the wires, use rubber and electricians tape liberally to insulate the connection.
