Each three steps in wire gage is about a 2x change in copper
cross section. For example, three 22AWG wires would have about
the same copper as a 17AWG . . . A blue (14-16AWG) butt splice
would be fine for what you propose . . .
The PROBLEM is that the circuit you've described must be protected
for 22AWG wire . . . it's okay to use 14AWG to extend a long circuit
for the purpose of lowering voltage drop but the circuit protection
needs to be sized for the SMALLEST wire in the circuit.
What is your application where the three way split seems necessary?
