Found another bonehead issue today.....
Alarm company used their stranded wire *terminal wire* and punched it down onto a standard RJ21X block (krone). I'll put money on it they either just ran it across the clips with a needle nose and or use a 66 head on it...
Is stranded even a ~acceptable~ wire to be used on IDC connectors.
Second, what gauge rating is acceptable in IDC connectors.
The wiring was real thin. I know, stranded feels thing. This stuff was like 26 gauge I presume....
Anyhow, ripped it out, ran solid back to their RJ31X screw terminals.
