Ooo, good to know, thanks! I am indeed on 120v, but I'm only doing lighting fixtures right now, so I'm not too worried about the increased resistance. I'll make sure not to use it on touchier circuits.
Yeah. One of the biggest downsides of 120V is the higher current needed for high wattage appliances (toaster ovens, kettles, hair dryers, air fryers, etc). This means you need heavier gauge wires and arc faults are more of a fire risk. On the other hand 120V is definitely safer.
