Crimp connector ratings
netdudeuk:
I have a set of low cost (red, yellow, blue) crimp connectors and I was hoping to put some of the fork ones onto the 240 VAC mains cable supplying a 5 volt 10 amp modular SMPS. However, they look pretty thin and I’m not sure that I would trust them with AC mains.
I had a look at RS (who didn’t supply these particular ones) but didn’t find electrical ratings as such. Wire sizes seemed to be the thing there.
Any advice please ?
Thanks

You could cover them with some heat shrink tube.

They are good for as many amps as the wire that crimps into them.

Its not the voltage that matters, its the current. If they can carry 5A at 12V, they are OK for 5A at any other voltage. As you are suspicious about their thickness, test them at 10A and low voltage on a similar terminal strip, and if they don't run hot, they'll be fine at 5A.

Make sure that you use the right tool to crimp them. Wrong or cheap crimp tools too often fail to do the job reliable. Do a pull test to see if the connection is done acceptable.
