    Isolator in the outdoor electrical box

    Hi there, I'm planning to replace the MCB on my outdoor electrical box with a better quality one, and since there is already an isolator installed by ESB Networks, as a DIY I can safely do it myself.

    Thoughts on heat-shrink tubing with internal adhesive liner for isolator poles?

    Now and again I nip a tiny faction too much off the incoming lines inserted into the isolator. As routine I heat-shrink over. However recently noticed the boss prefers to use adhesive lined shrink. Any thoughts regarding adhesive-lined shrinks being used on 100A isolator lines?

    Evening, I've been asked to install a supply to a sprinkler system in a new installation that must be separate to the building electrical services.

    Switch fuse or rotary isolator?

    Hi we have been asked to run a 3 phase supply into a boiler house to feed a DB fed from next to the existing meter. Would we need to install Tails to a switch fuse or could we just install a rotary isolator? Just tight for space near the Meter and switch fuses are big. Thanks
