That number drops to 50 feet if you run 12 gauge wire on a 20 amp circuit. You can run a 12 gauge wire up to 70 feet on a 15 amp circuit. Using connectors is the safer and more secure method and, done properly, gives a protected splice. You can use connectors and electrical tape, or you can buy a splice kit to secure the connection.
