Product defect or installation error?

[Mike Johnson]

Flex is multi strand wire as opposed to single strand, the bootlace ferrule referred to is a metal tube the multi strand is inserted into and the tube crimped around the flex and this is inserted into the slot and the screw tightened onto the ferrule.

I finally posted images! Let me know what you think or any questions.

What's the make/model of this timer? Seems a lot of corrosion on the (steel?) terminal screws for a unit that was only installed a couple of months ago.

I'd assumed heat damage, but upon enlargement of the image that termination screw on the right shows considerable evidence of corrosion.

The corrosion two of you mentioned is just because I had the damaged unit sitting outside after it was disconnected.
