really depends on the amp load and distance, you can probably get away with 14ga on most things under 10amps, 12ga up to 15 and 10ga for 16-30amp, and anything over 30 amps run an 8ga

150w at 12v is 12.5amps
1500w at 120v is 12.5amps
3% voltage drop at 12v is.36
3% voltage drop at 120 is 3.6
Length makes a big difference as resistance will increase and voltage drop will increase with resistance.
Correlating with a lower amp capacity for a given wire at a longer distance. Here’s where it changes. 4gauge at 240v will carry 10amps @1300’ where 4ga with 10a at 12v will only go 90’
