  • Terminal block usage.

    From peter@easthope.ca@21:1/5 to All on Fri Jul 5 20:44:19 2024
    Hello again,

    I'll be connecting wires to the terminal block of a motor controller.
    Two connections will each have two wires as illstrated here. http://easthope.ca/TerminalBlock.jpg

    Soldering the pair of wires together will keep them aligned when
    inserting. I understand that solder creeps. Is solder prohibited in
    this application? OK if applied sparingly?

    Should conductive paste be applied?

    Thanks, ... Peter E.

    I don't know about legality, but I will never solder wires that are to
    be clamped. They will loosen over time.

    Crimped ferrules seems to be a popular alternative.

    Your link bounces a 404, so I can't see exactly what you're
    talking about.

    This can depend on terminal block type/integrity, wire gauge
    and lead dressing. If in doubt, don't do it - use a connection
    method and materials that you are comfortable with and know
    will give reliable service.

    Juding from the apparent size of the conductors in your picture, tinning is definitely not recommended. If they're available in a small size, properly crimped wire ferrules would be the most recommended method of making these terminations.

    There is too much "compression creep" with tinned wires as I've experienced in the past.
