| This photo is from
the inside of a
Harris
HT-5 FM Broadcast Transmitter where 240 VAC power comes in. A
loose connection on the power connector block caused wires to burn-off.
Wires have been pulled back from the top center terminal of the block to
show the debris left from the incident. Insulation burned off the
overheated wires for about two inches from the block. The
connector will need to be replaced after a temporary repair is made.
This kind of problem is not just
seen on Harris transmitters. It can and does happen to all
transmitters where high-current conductors are terminated. Best to
check tightness of these kinds of connections whenever practical.
