Q: How many light strings can I put together?
A: According to Underwriters Laboratories, there should be a maximum of 210 watts connected on 22 gauge wire and a maximum of 420 watts connected on 20 gauge wire. Since each bulb and string has different wattage, calculate your total to see how many strings you can connect.
