Inside a screw type terminal block the block bore has to be shiny clean, as well as the copper strands that fit into it. A pass through connector bolt and nuts have to be SHINY clean, under the threads, flat washers sides, under the bolt head, the threads, everything. A 20 amp load applied to a semi bad connector can fire a wire in under 10-seconds, no matter how tight the screw or nut gets tightened. There is a hell of a difference between "no corrosion" and "shiny clean". To make things worse, an overheated connector or block can ANNEAL get too soft and cause problems later on. I would replace the burned wire, the connector fastener on BOTH sides or ends, and then check the outside wire and terminal with a magnifying glass. Not worth burning up at 3AM
