What size of crimp cap be used for 16 AWG wire? I could use butt splice of size 22-18 AWG but prefer crimp cap connector where both wires go in the same end (so double the diameter). Should I buy Crimp Cap 16/14 Gauge or Crimp Cap 12/10 Gauge. Does the listed gauge take into account that two wires would go in the same end?

A 16/14 cap should take between 1 and 4 #16 wires, but it depends on the cap. Specific information should be available on the packaging, or from the manufacturer.
