Old Fuseboard

    My Sisters house has an old fuseboard with a 63 amp main switch and a main fuse. Tonight she lost all power and on inspection I noticed that the main fuse contact on the board was blackened so I cleaned it by scraping off. I then replaced the main fuse and turned on the main switch. For a second some sparking could be seen and heard from the switch but then all seemed Ok. Would the switch need to be replaced? If so how could it be done, does the ESB have to come out and turn off power to the board? Thanks

    You need to call a registered electrician. The ESB have nothing to do with it.

    If it's sparking and arcing there's a potential fire hazard. I would call a REC very soon!

    I wouldn't suggest continuing to use it tbh.

    I realise it would have to be done by an electrician, just curious as to how they go about isolating power to the fuseboard

    It can be done live or you can pull the fused cut-out if you're lucky and there's play on the seal

    Other than that you'd have to ring esbn and they'll isolate the board

    Some will have the contractor isolator in the meter cabinet too ,so can be isolated there

    Be surprised if the consumer board is that old.

    He said old, presumably dz main fuse

    That's usually just meter and fused cut-out in the cabinet

    The meter is in the cabinet beside the fusebox yes. The cut out is inside the meter housing is it?

    Agree with the above. Sounds like this may be the time to upgrade the fuse board anyway. I would treat this as a warning.

    Agree with posters who say you need a rec to check this out
    If the fuseboard is upgraded you will need esbn involvement as main incoming cables may need to be upgraded.(16mm).The main bonding and protective conductors will need upgrading too(rod/gas/equipotential bonding etc)
    A certificate will have to be issued to facilitate termination into meter and neutralising earth connection. There is also a charge from esbn for this(@€;180)
