Stranded vs. Solid Wire


Does it make any real difference what’s used for any aspect of this project? By virtue of harvesting my surroundings, I’ve ended up with a mix of solid and stranded wire in the 120VAC module.

The solid wire appears to hold better in the relay contacts, but the stranded wire is definitely more flexible (duh…). Also, it seems generally more difficult to actually get all the strands of the stranded wire to go where I want - often a single strand will bunch up and poke out of whatever I’m trying to poke it into, which makes me fearful of shorts.

Is it just “whatever works”, or is there some benefit/downside of either of them for this project?


Both kinds of wire work fine. I’m using stranded wire in this module too.
