I'm living in a 3 storey building, having 1 house at each floor. It has single phase connection. Since when I installed A.C. in my house (on 2nd Floor), the fuse is getting burnt repeatedly.How can it be eradicated? Please help.

Have an electrician come in to check the load of the AC and check to determine if the wiring and fuse are of the correct size and capacity. AC units draw a large amount of current, and often apartments are not wired for large loads.

Also, make sure you replace the fuse with the same amperage as the one before (Example: 20 amp should have a 20 amp replacement), if you use a fuse with higher amperage you will have a fire hazard on your hands.
