well, i work with wagos as din rail terminals in industrial use from AWG 20 to AWG 2 or so daily, and i've never seen a faulty one of these getting hot or equal problems.

the cage clamp system [Linked Image from aerco.co.uk] clamps the wire at a pre-defined strenght that is not lost by the time, and it makes a perfect contact by distributing the strands evenly in the clamping zone.

this one is rated 32 Amperes by the VDE, so it should work perfect for 16A building installations.

saying wirenuts would be better/safer is just wrong IMHO. I dont trust Wirenuts at all, especially for stranded wires.
