    What type of connector to a 45 amp battery cable can I install to prevent arc flash?
    Also anyone have a clamp connection suggestion for this level of power to reconnect a cut wire instead of solder.

    thank you!!

    You cannot prevent arc flash only limit the effects.....depends what load current you are looking at as to whether or not any arc barrier contactor or solid state switcher is necessary.

    You could try a suitably sized magnet close to the contacts, acting as an arc blow out as fitted to many high current relays.

    Possible, but too early to say definitely.

    I don't think your concerned with Arc flash unless your talking about a battery bank with voltages exceeding 100v.
    Short circuit protection? Perhaps a fuse or fusable link.

    Compression lugs covered with shrink tubing are ideal for many applications.

    Its a electric surf board.
    with a 45 amp battery that makes a small pop noise when connecting the battery. See attached connector. . Batteryconnection.jpg Batteryconnection.jpg

    Thank you.
