I am re-wiring a very old lamp. The lamp has two curved arms that come out of a center cluster. The area they all come together is very small, with sharp turns. I can get 18/2 wire through one arm, but there is not enough room for the wire from the other arm.
Can I use 20/2 wire in each arm, and then attach them to 18/2 in the center? I have to use a pre-wired switch at the bottom of the lamp. I assume the switch uses 18/2 wire.
Each arm wnds in a small chandelier socket that will have a 25 watt chandelier bulb.
Is it safe to use 20/2 wire in the entire lamp?

When you state 20/2 and 18/2 are these cables? 2 conductors of fixture wire would be the way I would go high temp rating and easier to fish through the fixture arms. 25w on a 120v circuit would draw less than 1/2 amp 2017 NEC 402.6 states fixture wires shall not be smaller than 18 AWG. Table 402.5 shows 18 awg as 6 amps max.
