Reducing main fuse size

If your electricity consumption has decreased, you can opt for a smaller main fuse and save money by paying a lower basic charge. Ask your electrical contractor to check the size of main fuse that would cover your needs. You can order a change of main fuses from the contractor. 

The connection usage right will remain based on the previously used main fuse so that, if necessary, you can increase the main fuse up to the same size with no additional connection charge.
