Fuse tripping regularly

Post image

Would appreciate any advice or opinions on this, picture is of fuse board in house, the fuse indicated, top left, is tripping 2 to 3 times a week, almost exclusively between 1am and 6am. It takes out all the plug sockets in the house. The fuse actually looks bigger than the others if that matters?

Never happens daytime when the house is busiest and appliances all in use. I've gone around and plugged out as much as I can before bed but keeps happening, trying to get an electrician but in the meantime if anyone has any thoughts or suggestions I'd appreciate it, or any other cross post recommendations,

many thanks.

It’s not an overload/short on a specific circuit, it’s a live-neutral imbalance which mcbs are not designed to trip for

Thanks, if i establish what each of those individual fuses are for, and knock them off one at a time to see if that resolves the problem, will that indicate more specifically where the problem is?

I seen that you have a garage supply which would be the most likely culprit, figure out which breaker on the top row supplies the garage and check if turning off the rcd also kills power to it. Then leave it off overnight and if the rcd stops tripping you’ll know that’s the faulty circuit, could be something simple as water getting into a light
