    Best solution for locked DB's

    What is the best option to use for many, many D.Boards that have padlocks on as per picture.
    The Disconnector is not accessible. Some I have seen install an external isolator clearly marked.
    Some cut a hole in the DB front door. Some have a break glass box with a key for the lock.

    The main switch-disconnector on each distribution board shall be easily
    accessible. (See also 6.6.1.1(b), 6.6.1.1(c), 6.6.1.6 and 6.6.1.9.) If, owing to
    the nature of the installation, it is necessary to be able to interrupt the supply
    immediately, the switch-disconnector shall be so installed that it can be
    rapidly identified and operated.

    On the mines we drilled holes in the bottom and then connected trip lines to the main isolators.
    That was the standard so people could trip it.
