FYI Ferrule ends

[Joe Hogan]

When the wire for the Hughes Bulldog surge protector was swapped note the ferrules and tinned ends of OEM wire.
Discussed this with a Hughes engineer and he indicated that the concern is that the wire remains secure in the fitting.
I’ve attached an image of the OEM wire ends.
Over the next weeks the wire that replaced the OEM wire will be refitted with ferrules something like the second image attached.
Unfortunately when the OEM wire was swapped ferrules and crimp were not available.

When stranded wire goes under a screw, I always tin the end of the wire with solder. It compresses under pressure and keeps the individual strands in place. I know some will say it causes the wire to be stiff and will break. I view it if properly done, as being no stiffer than a crimped ferrule.

As a long term electronics technician, I was taught and still practice that you either solder the wire or crimp it, not both. The heat from soldering makes the wire brittle. Crimping makes wire brittle from pressure (heat).
Both are often too much for the wire and make strands prine to breakage.
