I need to connect 10 thin single-core wires to each other permanently. They will carry at most 1A at 5V in total (100mA each). Can I just solder them together in a lump with shrink wrap tubing around? Is there a better or more normal/professional way? The wago clips is useful for testing, but looks "temporary" and work-in-progress, so I'd like to remove them.
Sorry I don't know the wire gauges, but you'll get an idea from this picture.
