UL Requirements for Wire to PCB Connection
UL Requirements for Wire to PCB Connection
(OP)
Are there any UL requirements regarding wire attachment to PCBs?
Is it permissible to directly solder a wire to a PCB?
If so, what kind of strain relief is required?

Here is a drawing. The wire is 18 gauge stranded.
Any guidance is greatly appreciated.
Thank you.

No strain relief is required by UL at all..
We have hundreds of UL listed products where we simply solder anything from 24 to 14 AWG directly to the board without any relief at all. Never had a problem.
Now depending on the environment/vibration,etc.. that your specific product might see in its lifespan it would probably be a good idea to do something like #2 or other but its not required generically.

The need for strain relief is your call - what sort of forces will the leads be subjected to, etc...
