To answer this question the total wattage of the fixture is needed. To find this you need to find out the wattage of one bulb. If all of the bulbs are the same multiply the wattage of the bulb times 19. Use this total wattage in the following equation. I = W/E, Amps = Watts/Volts. In North America a #14 conductor is rated at 15 amps but has to be de-rated for a continuous load. This allows the conductor to carry 12 amps legally.
A #12 conductor is rated at 20 amps but has to be de-rated for a continuous load. This allows the conductor to carry 16 amps legally.
A #10 conductor is rated at 30 amps but has to be de-rated for a continuous load. This allows the conductor to carry 24 amps legally.
Hopefully the chandelier falls within this amperage range
In a floor lamp or table lamp a #16 wire is what you need.
10 AWG.
Wire gauges are defined in such a way that the lower the gauge, the thicker the wire. So, 8 gauge wire is thicker than 10 gauge wire.
Yes, you splice a small length of 16 gauge wire to 18 gauge wire for a repair.
The larger the wire gauge, the smaller the diameter. 12 gauge is bigger than 14 gauge.
possible fuse or bulb in dash. or worse a loose wire/rat bit a wire.
3/0 gauge
Use 8 gauge wire.
Wire gauge is used to determine the size wire needed to carry the correct amount of current for the job. It must be sized appropriately for the current in the circuit you are building.
4 gauge
The guage of wire for 20 amps is #12 copper.
AWG #6
2 AWG.
In a floor lamp or table lamp a #16 wire is what you need.
10 AWG.
At the service entrance you will need AWG 1/0 gauge.
As a service entrance wire you need AWG # 3/0 gauge copper.
