To answer your question about the ROMEX gauge, 15 amp circuits use 14 ga ROMEX and 20 amp circuits use 12 ga ROMEX. Go to the circuit breaker panel, determine what size circuit breaker is in the circuit, use ROMEX of that appropriate size.
As a warning: Using 14 ga ROMEX in a 20 amp circuit "could cause a fire hazard" as the wiring may get too hot before the circuit breaker opens.
