JCGD Posted November 10, 2022 Share Posted November 10, 2022 Moved into house recently and the unit looks like this. How do I isolate power? There only seems to be a switch for the master and not individual circuits. Link to comment Share on other sites More sharing options...
Radian Posted November 10, 2022 Share Posted November 10, 2022 You don't see many like that anymore. Pull out individual fuses to isolate the circuits - although I'd throw the main breaker first. Safety wasn't such a priority when these were installed. The fuse carrier will expose a certain amount of live conductor as it comes out. Link to comment Share on other sites More sharing options...

markc Posted November 10, 2022 Share Posted November 10, 2022 Old MEM board, sticky fuse, wiggle it about, plastic breaks up and you get a good crack from it. …. Not that I would know 😉 1 Link to comment Share on other sites More sharing options...

JCGD Posted November 10, 2022 Author Share Posted November 10, 2022 If I wanted to work on something around the house am I safer just knocking the mains off then? Link to comment Share on other sites More sharing options...

I'd be happy having a go at this, assuming I could just switch the main switch off and then change the MCBs. Link to comment Share on other sites More sharing options...
ProDave Posted November 10, 2022 Share Posted November 10, 2022 No. Any mcb's you find for that will be old / second hand, if you do find any new ones they will silly money. And an rcbo for that is like hens teeth. Spend the money on a new up to date consumer unit. 1 Link to comment Share on other sites More sharing options...

Do you think I need to order any extra MCBs etc? Link to comment Share on other sites More sharing options...
ProDave Posted November 10, 2022 Share Posted November 10, 2022 You will need one more 32A mcb as you presently have 6 30A fuses and that Cu conly comes with 5 32A mcb's. 1 Link to comment Share on other sites More sharing options...
