With time the Distribution box started to give trouble. the fuses became loose and the wires were deteriorated at junctions. Because of this the sensitive electronic equipment connected to these loops started giving trouble.
Finally, without being lazy I decided to replace the DB. Since I'm a Sri Lankan, I suggested my father we should by Orange; a Sri Lankan brand. Plus its 4 times less expensive than imported brands. The important brands carry a life time warranty whereas Orange has a two year warranty.
In a house hold, there are several loops so that a malfunctioning of one equipment will not trip the whole house at once. The live wire is fed to each MCB at the top and each loop begins from the MCB. All the neutral wires returning to the DB is connected to the neutral bus bar.
In the old system, this is how the live wire connected to one side of the fuses.
Just so that i won't mix up any wires, I labeled the live wires of the loop start.
Fixed the plastic box frame.
Fixed the MCB's and wired them.
Screwd in the cover and it's done.
