How many wires per nut

[Jon mackay]

Is there a standard of haw many wires can be secured under 1 wire nut?

This one has 5.

[Jim Port]

It depends. The information is included on the packaging for the connectors. A typical connector like that is good for 5 #12s, but should be checked.

[MARVIN TOWNSEN]

As many as you can fit:D

If you don't have the manufacture's chart handy, each manufacturer will have a have a link on their site to a document with the UL listing for each model and size of their connectors. For example here's the

Ideal Industries listing for their standard "Wire-Nut" type connectors (http://www.idealindustries.com/media/pdfs/products/references/ideal_ul_listed_combinations.pdf).
